Accounting Policies [Abstract]
Description of Business, Basis of Presentation and Summary of Significant Accounting Policies	Description of Business, Basis of Presentation and Summary of Significant Accounting Policies:
	Description of Business
	Cumulus Media Inc. (and its consolidated subsidiaries, except as the context may otherwise require, “Cumulus,” “Cumulus Media,” “we,” “us,” “our,” or the “Company”) is a Delaware corporation, organized in 2002, and successor by merger to an Illinois corporation with the same name that had been organized in 1997.
	Basis of Presentation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain assets of the Company were sold during the year ended December 31, 2013 (see Note 2, “Acquisitions and Dispositions”). The results of operations associated with these assets have been separately reported, net of the related tax impact, for all periods presented in the consolidated statements of operations because the operations and cash flows generated by these assets have been eliminated from the Company’s consolidated results of operations as a result of the sale, and the Company no longer has continuing involvement in the operations of the stations associated with those assets after their disposal (see Note 3, “Discontinued Operations”).
	Reclassifications
	Certain account balances in the 2013 and 2012 periods have been reclassified to conform with classifications currently in use. In the accompanying consolidated statements of operations, the Company separately presents content costs and other direct operating expenses as operating expense categories. In certain of the Company's historical disclosures, those line items were presented on a combined basis within the direct operating expenses line item in the statement of operations. Content costs consist of all costs related to the licensing, acquisition and development of the Company's programming. Other direct operating expenses consist of expenses related to the distribution and monetization of the Company's content across its platform and overhead expenses. There were no other costs included in direct operating expenses in 2014, 2013 or 2012.
	These reclassifications had no effect on previously reported results of operations, retained earnings or cash flows.
	Reportable Segment
	The Company operates in one reportable business segment, radio broadcasting, advertising and related services, for which segment disclosure is consistent with the management decision-making process that determines the allocation of resources and the measurement of performance. Below the reportable business segment, the Company has three reporting units (See Note 6, "Intangible Assets and Goodwill").
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to revenue recognition, bad debts, intangible assets, income taxes, stock-based compensation, contingencies, litigation, and purchase price allocation. The Company bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual amounts and results may differ materially from these estimates.
	Cash and Cash Equivalents
	The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.
	Accounts Receivable, Allowance for Doubtful Accounts and Concentration of Credit Risk
	Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on several factors including the length of time receivables are past due, trends and current economic factors. All balances are reviewed and evaluated quarterly on a consolidated basis. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers.
	In the opinion of management, credit risk with respect to accounts receivable is limited due to the large number of customers and the geographic diversification of the Company’s customer base. The Company performs ongoing credit evaluations of its customers and believes that adequate allowances for any uncollectible accounts receivable are maintained.
	Assets Held for Sale
	During the year ended December 31, 2014, the Company entered into an agreement to sell certain land and buildings to a third party. The agreement is subject to various terms including a 60 day due diligence period. The carrying value of the identified assets have been classified as held for sale in the consolidated balance sheet at December 31, 2014. The estimated fair value of the land and buildings is in excess of the carrying value.
	Property and Equipment
	Property and equipment are stated at cost. Property and equipment acquired in business combinations accounted for under the purchase method of accounting are recorded at their estimated fair values on the date of acquisition. Equipment held under capital leases is stated at the present value of minimum future lease payments.
	Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the assets. Equipment held under capital leases and leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the asset or the remaining term of the lease. Depreciation of construction in progress is not recorded until the assets are placed into service.
	Impairment of Long-Lived Assets
	Long-lived assets, such as property and equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.
	Intangible Assets and Goodwill
	The Company’s intangible assets are comprised of broadcast licenses, certain other intangible assets and goodwill. Goodwill is equal to the difference between the purchase price and the value assigned to the tangible and intangible assets acquired and liabilities assumed. Intangible assets and goodwill acquired in a business combination and determined to have an indefinite useful life, which include the Company’s broadcast licenses, are not amortized, but instead tested for impairment at least annually. Intangible assets with definite useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.
	In determining that the Company’s broadcast licenses qualified as indefinite lived intangibles, management considered a variety of factors including the Federal Communications Commission’s (“FCC”) historical record of renewing broadcast licenses, the cost to the Company of renewing such licenses, the relative stability and predictability of the radio industry and the relatively low level of capital investment required to maintain the physical plant of a radio station. The Company evaluates the recoverability of its indefinite-lived assets, which include broadcasting licenses and goodwill, using judgments and estimates. Future events may impact these judgments and estimates. If events or changes in circumstances were to indicate that an asset’s carrying value is not recoverable, a write-down of the asset would be recorded through a charge to operations.
	Investments
	The Company follows Accounting Standards Codification (“ASC”) Topic 325-20, Cost Method Investments (“ASC 325-20”) to account for its ownership interest in noncontrolled entities. Under ASC 325-20, equity securities that do not have readily determinable fair values (i.e., non-marketable equity securities) and are not required to be accounted for under the equity method are typically carried at cost (i.e., cost method investments). Investments of this nature are initially recorded at cost. Income is recorded for dividends received that are distributed from net accumulated earnings of the noncontrolled entity subsequent to the date of investment. Dividends received in excess of earnings subsequent to the date of investment are considered a return of investment and are recorded as reductions in the cost of the investment. Investments are written down only when there is clear evidence that a decline in value that is other than temporary has occurred. During the year ended December 31, 2014, the Company sold one of its cost method investments for $13.0 million, recognizing a gain on sale of $3.2 million, which is included in other income (expense), net in the consolidated statement of operations. As of December 31, 2014 and 2013, the aggregate carrying amount of the Company’s cost-method investments were $17.3 million and $9.9 million, respectively.
	Debt Issuance Costs
	The costs related to the issuance of debt are capitalized and amortized to interest expense over the life of the related debt using the effective interest method.
	Derivative Financial Instruments
	The Company recognizes all derivatives on the consolidated balance sheets at fair value. Fair value changes are recorded in income for any contracts not classified as qualifying hedging instruments.
	Revenue Recognition
	Revenue is derived primarily from the sale of commercial airtime to local and national advertisers. Revenue is recognized as commercials are broadcast. Revenues presented in the financial statements are reflected on a net basis, after the deduction of advertising agency fees by the advertising agencies, usually at a rate of 15.0%, which is the industry standard.
	In those instances in which we function as the principal in the transaction, the revenue and associated operating costs are presented on a gross basis. In those instances where we function as an agent or sales representative, our effective commission is presented as revenue with no corresponding operating expenses.
	Advertising Costs
	Advertising costs are expensed as incurred. For the years ended December 31, 2014, 2013, and 2012, the costs incurred were $1.9 million, $0.9 million and $1.1 million, respectively.
	Local Marketing Agreements
	In certain circumstances, the Company may enter into a local marketing agreement (“LMA”) or time brokerage agreement with a FCC licensee of a radio station. In a typical LMA, the licensee of the station makes available, for a fee, airtime on its station to a party, which supplies programming to be broadcast on that airtime, and collects revenues from advertising aired during such programming. Revenues earned and fees incurred pursuant to LMAs or time brokerage agreements are recognized at their gross amounts in the accompanying consolidated statements of operations.
	As of December 31, 2014, the Company operated 11 radio stations under LMAs. As of December 31, 2013 and 2012, the Company operated 7 and 14 radio stations under LMAs, respectively. The stations operated under LMAs contributed $22.6 million, $2.2 million, and $7.0 million, in 2014, 2013, and 2012, respectively, to the consolidated net revenues of the Company.
	Stock-based Compensation Expense
	Stock-based compensation expense recognized under ASC Topic 718, Compensation — Share-Based Payment (“ASC 718”), for the years ended December 31, 2014, 2013 and 2012, was $17.6 million, $10.8 million, and $11.9 million, respectively. Upon adopting ASC 718 for awards with service conditions, an election was made to recognize stock-based compensation expense on a straight-line basis over the requisite service period for the entire award. For stock options with service conditions only, the Company utilizes the Black-Scholes option pricing model to estimate the fair value of options issued. For restricted stock awards with service conditions, the Company utilizes the intrinsic value method. For restricted stock awards with performance conditions, the Company evaluates the probability of vesting of the awards in each reporting period and adjusts compensation cost based on this assessment. The fair value is based on the use of certain assumptions regarding a number of highly complex and subjective variables. If other assumptions are used, the results could differ.
	Trade Transactions
	The Company provides commercial airtime in exchange for goods and services used principally for promotional, sales and other business activities. An asset and liability is recorded at the fair value of the goods or services received. Trade revenue is recorded and the liability is relieved when commercials are broadcast and trade expense is recorded and the asset relieved when goods or services are consumed. Trade valuation is based upon management’s estimate of the fair value of the products, supplies and services received. For the years ended December 31, 2014, 2013 and 2012, amounts reflected under trade transactions were: (1) trade revenues of $34.9 million, $31.1 million and $27.7 million, respectively; and (2) trade expenses of $36.8 million, $31.2 million and $26.1 million, respectively.
	Income Taxes
	The Company uses the liability method of accounting for deferred income taxes. Deferred income taxes are recognized for all temporary differences between the tax and financial reporting bases of the Company’s assets and liabilities based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. A valuation allowance is recorded for a net deferred tax asset balance when it is more likely than not that the benefits of the tax asset will not be realized. The Company continues to assess the need for its deferred tax asset valuation allowance in the jurisdictions in which it operates. Any adjustment to the deferred tax asset valuation allowance is recorded in the income statement of the period that the adjustment is determined to be required. See Note 14, “Income Taxes” for further discussion.
	Earnings per Share
	Basic income (loss) per share is computed on the basis of the weighted average number of common shares outstanding. The Company allocates undistributed net income (loss) from continuing operations between each class of common stock on an equal basis after any allocations for preferred stock dividends in accordance with the terms of the Company’s third amended and restated certificate of incorporation (the “Third Amended and Restated Charter”).
	Non-vested restricted shares of Class A common stock and Company Warrants (defined below) are considered participating securities for purposes of calculating basic weighted average common shares outstanding in periods in which the Company records net income. Diluted earnings per share is computed in the same manner as basic earnings per share after assuming the issuance of common stock for all potentially dilutive equivalent shares, which includes stock options and certain other outstanding warrants to purchase common stock. Antidilutive instruments are not considered in this calculation. Under the two-class method, net income is allocated to common stock and participating securities to the extent that each security may share in earnings, as if all of the earnings for the period had been distributed. Earnings are allocated to each participating security and common share equally, after deducting dividends declared or accreted on preferred stock.
	Fair Values of Financial Instruments
	The carrying values of cash equivalents, accounts receivables, accounts payable, and accrued expenses approximate fair value due to the short term to maturity of these instruments (See Note 10, "Fair Value Measurements").
	Accounting for National Advertising Agency Contract
	The Company has engaged Katz Media Group, Inc. (“Katz”) as its national advertising sales agent. The Company’s contract with Katz has several economic elements that principally reduce the overall expected commission rate below the stated base rate. The Company estimates the overall expected commission rate over the entire contract period and applies that rate to commissionable revenue throughout the contract period with the goal of estimating and recording a stable commission rate over the life of the contract.
	The potential commission adjustments are estimated and combined in the consolidated balance sheets with the contractual termination liability. That liability is accreted to commission expense to effectuate the stable commission rate over the term of the Katz contract. Over the term of the contract with Katz, management updates its assessment of the effective commission expense attributable to national sales in an effort to record a consistent commission rate in each period.
	The Company’s accounting for and calculation of commission expense to be realized over the life of the Katz contract requires management to make estimates and judgments that affect reported amounts of commission expense in each period. Actual results in any period may differ from management’s estimates.
	Variable Interest Entities
	The Company accounts for entities qualifying as variable interest entities (“VIEs”) in accordance with ASC Topic 810, Consolidation (“ASC 810”). VIEs are required to be consolidated by the primary beneficiary. The primary beneficiary is the entity that holds the majority of the beneficial interests in the VIE. A VIE is an entity for which the primary beneficiary’s interest in the entity can change with changes in factors other than the amount of investment in the entity. From time to time, the Company enters into LMAs in connection with pending acquisitions or dispositions of radio stations and the requirements of ASC 810 may apply, depending on the facts and circumstances related to each transaction.
	Adoption of New Accounting Standards
	ASU 2013-04. In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-04, which provides guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements where the total obligation is fixed at the reporting date, and for which no specific guidance currently exists. The Company adopted this guidance effective January 1, 2014. The adoption of this guidance did not have an impact on the consolidated financial statements.
	ASU 2013-11. In July 2013, the FASB issued ASU 2013-11. The amendments in this ASU clarify when a liability related to an unrecognized tax benefit should be presented in the financial statements as a reduction to the related deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. The Company adopted this guidance effective January 1, 2014. The adoption of this guidance did not have an impact on the consolidated financial statements.
	Recent Accounting Standards Updates
	ASU 2014-08. In April 2014, the FASB issued ASU 2014-08. Under this ASU, only disposals that represent a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. This ASU (1) expands the disclosure requirements for disposals that meet the definition of a discontinued operation, (2) requires entities to disclose information about disposals of individually significant components, (3) defines “discontinued operations” similarly to how it is defined under International Financial Reporting Standards ("IFRS") 5, and (4) requires entities to expand their disclosures about discontinued operations to include more information about assets, liabilities, income and expenses. In addition, this ASU will also require entities to disclose the pre-tax income attributable to a disposal of “an individually significant component of an entity that does not qualify for discontinued operations presentation in the financial statements.” The ASU is effective prospectively for all disposals (or classifications as held for sale) that occur within annual periods beginning on or after December 15, 2014 and interim periods within those years. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the consolidated financial statements.
	ASU 2014-09. In May 2014, the FASB issued ASU 2014-09. The amended guidance under this ASU outlines a single comprehensive revenue model for entities to use in accounting for revenue arising from contracts with customers. The guidance supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the single comprehensive revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” Entities have the option of using either a full retrospective or modified approach to adopt the guidance. The ASU is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016 (early adoption is not permitted). The Company is currently assessing the expected impact, if any, that this ASU will have on the consolidated financial statements.
ASU 2014-15. In August 2014, the FASB issued ASU 2014-15. The amendments in this update provide guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. In doing so, the amendments should reduce diversity in the timing and content of footnote disclosures. The amendments in this ASU are effective for public and nonpublic entities for annual periods ending after December 15, 2016, and interim periods thereafter. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the consolidated financial statements.
ASU 2015-01. In January 2015, the FASB issued ASU 2015-01. The amendments in this ASU eliminate the concept of an extraordinary item from GAAP. As a result, an entity will no longer be required to segregate extraordinary items from the results of ordinary operations, to separately present an extraordinary item on its income statement, net of tax, after income from continuing operations or to disclose income taxes and earnings-per-share data applicable to an extraordinary item. However, the ASU will still retain the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. The ASU will be effective for fiscal years beginning December 1, 2016 and subsequent interim periods. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the consolidated financial statements.

The Company performs its annual impairment testing of broadcast licenses and goodwill during the fourth quarter and on an interim basis if events or circumstances indicate that broadcast licenses or goodwill may be impaired. The calculation of the fair value of each reporting unit is prepared using an income approach and discounted cash flow methodology. If the carrying value exceeds the estimate of fair value, the Company calculates impairment as the excess of the carrying value of goodwill over its estimated fair value and charges the impairment to results of operations in the period in which the impairment occurred. The Company reviews the carrying value of its definite-lived intangible assets for recoverability whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. There were no asset impairment charges during the years ended December 31, 2014 or 2013.
	Total amortization expense related to the Company’s intangible assets was $80.0 million, $86.7 million and $112.2 million for the years ended December 31, 2014, 2013, and 2012, respectively. As of December 31, 2014, estimated future amortization expense related to intangible assets subject to amortization was as follows (dollars in thousands):
	2015	$	69,110
	2016	56,315

	2014 Impairment Testing
	The Company performs its annual impairment testing of goodwill during the fourth quarter and on an interim basis if events or circumstances indicate that goodwill may be impaired. The calculation of the fair value of each reporting unit is prepared using an income approach and discounted cash flow methodology.
	The Company has three reporting units for goodwill impairment purposes which align with Company's operational structure of three distinct verticals used to effectively manage the operations of the business. The Company's top 50 Nielsen Audio rated markets and WestwoodOne comprise one reporting unit, the second reporting unit consists of all of the Company's other radio markets while the third reporting unit, in which there is no goodwill, consists of all non-radio lines of business.
	During the fourth quarter of 2014, the Company performed its annual impairment test. The assumptions used in estimating the fair values of reporting units are based on currently available data at the time the test is conducted and management’s best estimates and accordingly, a change in market conditions or other factors could have a material effect on the estimated values.
	Step 1 Goodwill Test
	The Company performed its annual impairment testing of goodwill using a discounted cash flow analysis, an income approach. The discounted cash flow approach requires the projection of future cash flows and the calculation of these cash flows into their present value equivalent via a discount rate. The Company used an approximate five-year projection period to derive operating cash flow projections from a market participant view. The Company made certain assumptions regarding future revenue growth based on industry market data and historical and expected performance. The Company then projected future operating expenses in order to derive expected operating profits, which the Company combined with expected working capital additions and capital expenditures to determine expected operating cash flows.
	The Company performed the Step 1 test and compared the fair value of each reporting unit to the carrying value of its net assets as of December 31, 2014. This test was used to determine if any of the Company’s reporting units had an indicator of impairment (i.e. the market net asset carrying value was greater than the calculated fair value of the reporting unit).
	The discount rate employed in the fair value calculations in the Step 1 test in the Company’s markets was 8.0%. The Company believes this discount rate was appropriate and reasonable for estimating the fair value of the reporting units.
	For periods after 2014, the Company projected annual revenue growth based on industry data and historical and expected performance. The Company projected expense growth based primarily on the stations’ historical financial performance and expected growth. The Company’s projections were based on then-current market and economic conditions and the Company’s historical knowledge of the reporting units.
	To validate the Company’s conclusions and determine the reasonableness of the Company’s assumptions, the Company conducted an overall check of the Company’s fair value calculations by comparing the implied fair value of the Company’s reporting units, in the aggregate, to the Company’s market capitalization as of December 31, 2014. As compared with the market capitalization value of $3.5 billion as of December 31, 2014, the aggregate fair value of all reporting units of approximately $3.6 billion was approximately $0.1 billion, or 2.9%, higher than the market capitalization.
	Key data points included in the market capitalization calculation were as follows:
	•	shares outstanding, including certain warrants, of 236.3 million as of December 31, 2014;
	•	closing price of the Company’s Class A common stock on December 31, 2014, of $4.23 per share; and
	•	total debt of $2.5 billion on December 31, 2014.
	Step 2 Goodwill Test
	The Company’s analysis determined that, based on its Step 1 goodwill test, the fair value of its reporting units containing goodwill balances exceeded their carrying value at December 31, 2014. As a result, the Company was not required to perform a Step 2 test.
	Indefinite Lived Intangibles (FCC Licenses)
	The Company performs its annual impairment testing of indefinite-lived intangibles (the Company’s FCC licenses) during the fourth quarter of each year and on an interim basis if events or circumstances indicate that the asset may be impaired. The Company has combined all of the Company’s broadcast licenses within a single geographic market cluster into a single unit of accounting for impairment testing purposes. As part of the overall planning associated with the indefinite-lived intangibles test, the Company determined that the Company’s geographic markets are the appropriate unit of accounting for the broadcast license impairment testing.
	For the annual impairment test of the Company’s FCC licenses, including both AM and FM licenses, the Company utilized the income approach, specifically the Greenfield Method. This approach values the license by calculating the value of a hypothetical start-up company that goes into business with no assets except the asset to be valued (the license). The value of the asset under consideration can be considered as equal to the value of this hypothetical start-up company. In completing the appraisals, the Company conducted a thorough review of all aspects of the assets being valued.
	The income approach measures value based on income generated by the subject property, which is then analyzed and projected over a specified time and capitalized at an appropriate market rate to arrive at the estimated value. The Greenfield Method isolates cash flows attributable to the subject asset using a hypothetical start-up approach.
	The estimated fair values of the Company’s FCC licenses represent the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between the Company and willing market participants at the measurement date. The estimated fair value also assumes the highest and best use of the asset by market participants, considering the use of the asset that is physically possible, legally permissible and financially feasible.
	A basic assumption in the Company’s valuation of these FCC licenses was that these radio stations were new radio stations, signing on-the-air as of the date of the valuation. The Company assumed the competitive situation that existed in those markets as of that date, except that these stations were just beginning operations. In doing so, the Company bifurcated the value of going concern and any other assets acquired, and strictly valued the FCC licenses.
	In estimating the value of the licenses using a discounted cash flow analysis, the Company began with market revenue projections. Next, the Company estimated the percentage of the market’s total revenue, or market share, that market participants could reasonably expect an average start-up station to attain, as the well as the duration (in years) required to reach the average market share. The estimated average market share was computed based on market share data, by type (i.e., AM and FM).
	After market revenue and market shares have been estimated, operating expenses, including depreciation based on assumed investments in fixed assets and future capital expenditures, of a start-up station or operation are similarly estimated based on industry-average cost data. Appropriate estimated income taxes are then subtracted, estimated depreciation added back, estimated capital expenditures subtracted, and estimated working capital adjustments are made to calculate estimated free cash flow during the build-up period until a steady state or mature “normalized” operation is achieved.
	The Company discounted the net free cash flows using an after-tax weighted average cost of capital of 8.0%, and then calculated the total discounted net free cash flows. For net free cash flows beyond the projection period, the Company estimated a perpetuity value, and then discounted the amounts to present values.
	In order to estimate what listening audience share would be expected for each station by market, the Company analyzed the average local commercial share garnered by similar AM and FM stations competing in those radio markets. The Company made any appropriate adjustments to the listening share and revenue share based on the stations’ signal coverage within the market and the surrounding area population as compared to the other stations in the market. Based on the Company’s knowledge of the industry and familiarity with similar markets, the Company determined that approximately three years would be required for the stations to reach maturity. The Company also incorporated the following additional assumptions into the discounted cash flow valuation model:
•	the projected operating revenues and expenses through 2019;
•	the estimation of initial and on-going capital expenditures (based on market size);
•	depreciation on initial and on-going capital expenditures (the Company calculated depreciation using accelerated double declining balance guidelines over five years for the value of the tangible assets necessary for a radio station to go on-the-air);
•	the estimation of working capital requirements (based on working capital requirements for comparable companies);
•	the calculations of yearly net free cash flows to invested capital; and
•	amortization of the intangible asset — the FCC license.
As a result of the annual impairment test conducted in the fourth quarter of 2014, the Company determined that no impairment existed for the FCC licenses.

	Interest Rate Cap
	On December 8, 2011, the Company entered into an interest rate cap agreement with JPMorgan Chase Bank, N.A. ("JPMorgan"), to limit the Company’s exposure to interest rate risk on its variable rate debt. The interest rate cap has an aggregate notional amount of $71.3 million. The agreement caps the LIBOR-based variable interest rate component of the Company’s long-term debt at a maximum of 3.0% on an equivalent amount of the Company’s term loans. The consolidated balance sheets as of December 31, 2014 and 2013 include long-term assets of less than $0.1 million and attributable to the fair value of the interest rate cap. The Company reported interest expense of less than $0.1 million, $0.1 million and $0.3 million during the years ended December 31, 2014, 2013 and 2012, respectively, attributed to the change in fair value adjustment. The interest rate cap matures on December 8, 2015.
	The Company does not utilize financial instruments for trading or other speculative purposes.
	Green Bay Option
	On April 10, 2009, Clear Channel and the Company entered into an LMA pursuant to which the Company was responsible for operating (i.e., programming, advertising, etc.) five radio stations in Green Bay, Wisconsin, for a monthly fee payable to Clear Channel of approximately $0.2 million, in exchange for the Company retaining the operating profits for managing the radio stations. In 2013, Clear Channel exercised the put option contained in this LMA, which required the Company to purchase the five Green Bay radio stations subject to the LMA for $17.6 million (the fair value of those radio stations at the time of execution of the LMA) ("the Green Bay Option"). On December 31, 2013, the Company completed the Green Bay Purchase (See Note 2, "Acquisitions and Dispositions")
	The Company accounted for the Green Bay Option as a derivative contract. Accordingly, the fair value of the Green Bay Option was recorded as a liability with subsequent changes in the fair value recorded through earnings through the closing of the acquisition. The fair value of the Green Bay Option was determined using inputs that were supported by little or no market activity (a “Level 3” measurement). The fair value represented an estimate of the amount that the Company would have been required to pay if the option were transferred to another party as of the date of the valuation.

	Amended and Restated Credit Agreement
	On December 23, 2013, the Company entered into an Amended and Restated Credit Agreement (the “Credit Agreement”), among the Company, Cumulus Media Holdings Inc., a direct wholly-owned subsidiary of the Company (“Cumulus Holdings”), as borrower, and certain lenders and agents. The Credit Agreement consists of a $2.025 billion term loan (the “Term Loan”) maturing in December 2020 and a $200.0 million revolving credit facility (the “Revolving Credit Facility”) maturing in December 2018. Under the Revolving Credit Facility, up to $30.0 million of availability may be drawn in the form of letters of credit.
	Term Loan borrowings and borrowings under the Revolving Credit Facility bear interest, at the option of Cumulus Holdings, based on the Base Rate (as defined below) or the London Interbank Offered Rate (“LIBOR”), in each case plus 3.25% on LIBOR-based borrowings and 2.25% on Base Rate-based borrowings. LIBOR-based borrowings are subject to a LIBOR floor of 1.0% under the Term Loan. Base Rate-based borrowings are subject to a Base Rate Floor of 2.0% under the Term Loan. Base Rate is defined, for any day, as the fluctuating rate per annum equal to the highest of the (i) Federal Funds Rate, as published by the Federal Reserve Bank of New York, plus 1/2 of 1.0%, (ii) prime commercial lending rate of JPMorgan Chase Bank, N.A., as established from time to time, and (iii) 30 day LIBOR plus 1.0%. Amounts outstanding under the Term Loan amortize at a rate of 1.0% per annum of the original principal amount of the Term Loan, payable quarterly, commencing March 31, 2014, with the balance payable on the maturity date.
	At December 31, 2014, the Term Loan bore interest at 4.25% per annum.
	The representations, covenants and events of default in the Credit Agreement are customary for financing transactions of this nature. Events of default in the Credit Agreement include, among others: (a) the failure to pay when due the obligations owing thereunder; (b) the failure to comply with (and not timely remedy, if applicable) certain covenants; (c) certain defaults and accelerations under other indebtedness; (d) the occurrence of bankruptcy or insolvency events; (e) certain judgments against the Company or any of its restricted subsidiaries; (f) the loss, revocation or suspension of, or any material impairment in the ability to use one or more of, any material FCC licenses; (g) any representation or warranty made, or report, certificate or financial statement delivered, to the lenders subsequently proven to have been incorrect in any material respect; and (h) the occurrence of a Change in Control (as defined in the Credit Agreement). Upon the occurrence of an event of default, the lenders may terminate the loan commitments, accelerate all loans and exercise any of their rights under the Credit Agreement and the ancillary loan documents as a secured party.
	In the event amounts are outstanding under the Revolving Credit Facility or any letters of credit are outstanding that have not been collateralized by cash, the Credit Agreement requires compliance with a consolidated first lien net leverage ratio covenant as of the end of each quarter. The required ratio at December 31, 2014 and 2013 was 5.75 to 1. The ratio periodically decreases until it reaches to 4.0 to 1 on March 31, 2018. As of December 31, 2014, the Company was in compliance with all of its covenants under the Credit Agreement.
	Certain mandatory prepayments on the Term Loan are required upon the occurrence of specified events, including upon the incurrence of certain additional indebtedness, upon the sale of certain assets and upon the occurrence of certain condemnation or casualty events, and from excess cash flow.
	The Company’s, Cumulus Holdings’ and their respective restricted subsidiaries’ obligations under the Credit Agreement are collateralized by a first priority lien on substantially all of the Company’s, Cumulus Holdings’ and their respective restricted subsidiaries’ assets (excluding the Company's accounts receivable collateralizing the Company's revolving accounts receivable securitization facility (the "Securitization Facility") with General Electric Capital Corporation ("GE") as described below) in which a security interest may lawfully be granted, including, without limitation, intellectual property and substantially all of the capital stock of the Company’s direct and indirect domestic wholly-owned subsidiaries and 66% of the capital stock of any future first-tier foreign subsidiaries. In addition, Cumulus Holdings’ obligations under the Credit Agreement are guaranteed by the Company and substantially all of its restricted subsidiaries, other than Cumulus Holdings.
	At December 31, 2014, the Company had $1.904 million outstanding under the Term Loan and no amounts outstanding under the Revolving Credit Facility.
	7.75% Senior Notes
	On May 13, 2011, the Company issued $610.0 million aggregate principal amount of 7.75% Senior Notes due 2019 (the “7.75% Senior Notes”). Proceeds from the sale of the 7.75% Senior Notes were used to, among other things, repay the $575.8 million outstanding under the term loan facility under the Company's prior credit agreement.
	On September 16, 2011, the Company and Cumulus Holdings entered into a supplemental indenture with the trustee under the indenture governing the 7.75% Senior Notes which provided for, among other things, the (i) assumption by Cumulus Holdings of all obligations of the Company; (ii) substitution of Cumulus Holdings for the Company as issuer; (iii) release of the Company from all obligations as original issuer; and (iv) Company’s guarantee of all of Cumulus Holdings’ obligations, in each case under the indenture and the 7.75% Senior Notes.
	Interest on the 7.75% Senior Notes is payable on May 1 and November 1 of each year. The 7.75% Senior Notes mature on May 1, 2019.
	Cumulus Holdings, as issuer of the 7.75% Senior Notes, may redeem all or part of the 7.75% Senior Notes at any time on or after May 1, 2015. At any time prior to May 1, 2014, Cumulus Holdings may also redeem up to 35.0% of the 7.75% Senior Notes using the proceeds from certain equity offerings. At any time prior to May 1, 2015, Cumulus Holdings may redeem some or all of the 7.75% Senior Notes at a price equal to 100% of the principal amount, plus a “make-whole” premium. If Cumulus Holdings sells certain assets or experiences specific kinds of changes in control, it will be required to make an offer to purchase the 7.75% Senior Notes.
	The indenture governing the 7.75% Senior Notes contains representations, covenants and events of default customary for financing transactions of this nature. At December 31, 2014, the Company was in compliance with all required covenants under the indenture governing the 7.75% Senior Notes.
	In connection with the substitution of Cumulus Holdings as the issuer of the 7.75% Senior Notes, the Company has also guaranteed the 7.75% Senior Notes. In addition, each existing and future domestic restricted subsidiary that guarantees the Company’s indebtedness, Cumulus Holdings’ indebtedness or indebtedness of the Company’s subsidiary guarantors (other than the Company’s subsidiaries that hold the licenses for the Company’s radio stations) guarantees, and will guarantee, the 7.75% Senior Notes. The 7.75% Senior Notes are senior unsecured obligations of Cumulus Holdings and rank equally in right of payment to all existing and future senior unsecured debt of Cumulus Holdings and senior in right of payment to all future subordinated debt of Cumulus Holdings. The 7.75% Senior Notes guarantees are the Company’s and the other guarantors’ senior unsecured obligations and rank equally in right of payment to all of the Company’s and the other guarantors’ existing and future senior debt and senior in right of payment to all of the Company’s and the other guarantors’ future subordinated debt. The 7.75% Senior Notes and the guarantees are effectively subordinated to any of Cumulus Holdings’, the Company’s or the guarantors’ existing and future secured debt to the extent of the value of the assets securing such debt. In addition, the 7.75% Senior Notes and the guarantees are structurally subordinated to all indebtedness and other liabilities, including preferred stock, of the Company’s non-guarantor subsidiaries, including all of the liabilities of the Company’s and the guarantors’ foreign subsidiaries and the Company’s subsidiaries that hold the licenses for the Company’s radio stations.
	For the year ended December 31, 2014, the Company recorded an aggregate of $9.5 million of amortization of debt discount and debt issuance costs related to its Term Loan, Securitization Facility and 7.75% Senior Notes. For the year ended December 31, 2013, the Company recorded an aggregate of $9.9 million of amortization of debt discount and debt issuance costs related to its first lien and second lien credit facilities and 7.75% Senior Notes.
	Accounts Receivable Securitization Facility
	On December 6, 2013, the Company entered into a 5-year, $50.0 million Securitization Facility with GE, as a lender, as a swingline lender and as an administrative agent (together with any other lenders party thereto from time to time, the “Lenders”).
	In connection with the entry into the Securitization Facility, pursuant to a Receivables Sale and Servicing Agreement, dated as of December 6, 2013 (the “Sale Agreement”), certain subsidiaries of the Company (collectively, the “Originators”) may sell and/or contribute their existing and future accounts receivable (representing all of the Company's accounts receivable) to a special purpose entity and wholly owned subsidiary of the Company (the “SPV”). The SPV may thereafter make borrowings from the Lenders, which borrowings will be secured by those receivables, pursuant to a Receivables Funding and Administration Agreement, dated as of December 6, 2013 (the “Funding Agreement”). Cumulus Holdings services the accounts receivable on behalf of the SPV.
	Advances available under the Funding Agreement at any time are subject to a borrowing base determined based on advance rates relating to the value of the eligible receivables held by the SPV at that time. The Securitization Facility matures on December 6, 2018, subject to earlier termination at the election of the SPV. Advances bear interest based on either LIBOR plus 2.50% or the Index Rate (as defined in the Funding Agreement) plus 1.00%. The SPV is also required to pay a monthly fee based on any unused portion of the Securitization Facility. The Securitization Facility contains representations and warranties, affirmative and negative covenants, and events of default that are customary for financings of this type. As of December 31, 2014, the Company was in compliance with all required covenants under the Securitization Facility.
	During the year ended December 31, 2013, the Company capitalized $0.9 million of deferred financing costs related to the Securitization Facility. At December 31, 2014, there were no amounts outstanding under the Securitization Facility.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The three levels of the fair value hierarchy to be applied to financial instruments when determining fair value are described below:
	Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the ability to access;
	Level 2 — Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities; and
	Level 3 — Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company’s financial assets and liabilities are measured at fair value on a recurring basis and non-financial assets and liabilities are measured at fair value on a non-recurring basis. Fair values as of December 31, 2014 and 2013 were as follows (dollars in thousands):

	-1	The Company’s only derivative financial instrument is the interest rate cap pursuant to which the Company pays a fixed interest rate on a $71.3 million notional amount of its term loans. The fair value of the interest rate cap is determined based on discounted cash flow analysis on the expected future cash flows using observable inputs, including interest rates and yield curves. Derivative valuations incorporate adjustments that are necessary to reflect the credit risk.
	-2	On September 13, 2013, the Company and Pulser Media, Inc. (the parent company of Rdio) ("Pulser"), entered into a five year strategic promotional partnership and sales arrangement (the "Rdio Agreement"). In exchange for $75 million of promotional commitments over five years, Cumulus will receive a 15% equity interest in Pulser, with the opportunity to earn additional equity, see Note 17, "Commitments and Contingencies". The fair value of the equity interest in Pulser was determined using inputs that are supported by little or no market activity (a Level 3 measurement). At December 31, 2014, the fair value of the equity interest in Pulser approximated its cost basis and the Company determined that the investment was not impaired.
	-3	The fair value of the contingent consideration was determined using inputs that are supported by little or no market activity (a Level 3 measurement). Contingent consideration represents the fair value of the additional cash consideration potentially payable as part of the WFME Asset Exchange and Wise Brothers Acquisition. See Note 2, “Acquisitions and Dispositions”.
	The assets associated with the Company’s interest rate cap are measured within Level 2 of the fair value hierarchy.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity
	The Company is authorized to issue an aggregate of 1,450,644,871 shares of stock divided into four classes consisting of: (i) 750,000,000 shares designated as Class A common stock, (ii) 600,000,000 shares designated as Class B common stock, (iii) 644,871 shares designated as Class C common stock and (iv) 100,000,000 shares of preferred stock, each with a par value of $0.01 per share (see Note 12, “Redeemable Preferred Stock”).
	On October 16, 2013, the Company issued and sold 18,860,000 shares of its Class A common stock in an underwritten public offering, which included the full exercise of the underwriter’s over allotment option to purchase 2,460,000 shares, at a price of $5.00 per share. The Company received net proceeds after underwriting discounts, commissions and estimated offering expenses of $89.8 million and used approximately $78.0 million of the net proceeds from the offering to redeem all then-outstanding shares of the Company’s Series B preferred stock, including accrued and unpaid dividends. The remaining net proceeds from the offering were placed in the Company’s corporate treasury for general corporate purposes and may be used from time to time for, among other things, repayment of debt, capital expenditures, the financing of possible business expansions and acquisitions, increasing the Company’s working capital and the financing of ongoing operating expenses and overhead.
	Common Stock
	Except with regard to voting and conversion rights, shares of Class A, Class B and Class C common stock are identical in all respects. The preferences, qualifications, limitations, restrictions, and the special or relative rights in respect of the common stock and the various classes of common stock are as follows:
	•	Voting Rights. The holders of shares of Class A common stock are entitled to one vote per share on any matter submitted to a vote of the stockholders of the Company, and the holders of shares of Class C common stock are entitled to ten votes for each share of Class C common stock held. Generally, the holders of shares of Class B common stock are not entitled to vote on any matter. However, holders of Class B common stock and Class C common stock are entitled to a separate class vote on any amendment or modification of any specific rights or obligations of the holders of Class B common stock or Class C common stock, respectively, that does not similarly affect the rights or obligations of the holders of Class A common stock. The holders of Class A common stock and of Class C common stock vote together, as a single class, on all matters submitted to a vote of the stockholders of the Company.
	•	Conversion. Each holder of Class B common stock and Class C common stock is entitled to convert at any time all or any part of such holder’s shares into an equal number of shares of Class A common stock; provided, however, that to the extent that such conversion would result in the holder holding more than 4.99% of the shares of Class A common stock immediately following such conversion, the holder shall first deliver to the Company an ownership certification to enable the Company (a) to determine that such holder does not have an attributable interest in another entity that would cause the Company to violate applicable FCC rules and regulations and (b) to obtain any necessary approvals from the FCC or the Department of Justice. During the year ended December 31, 2014, all of the approximately 15.4 million shares of outstanding Class B common stock were converted into shares of Class A common stock.
	2009 Warrants
	In June 2009, in connection with the execution of an amendment to the Company's then-outstanding credit agreement, the Company issued warrants to the lenders thereunder that allow them to acquire up to 1.3 million shares of Class A common stock at an exercise price of $1.17 per share (the “2009 Warrants”). The 2009 Warrants expire on June 29, 2019. The number of shares of Class A common stock issuable upon exercise of the 2009 Warrants is subject to adjustment in certain circumstances, including upon the payment of a dividend in shares of Class A common stock. At December 31, 2014, 0.4 million 2009 Warrants remained outstanding.
	CMP Restated Warrants
	In connection with the completion of our acquisition of Cumulus Media Partners, LLC ("CMP") in 2011, a subsidiary of CMP entered into an amended and restated warrant agreement, dated as of August 1, 2011 (the “Restated Warrant Agreement”). Pursuant to the Restated Warrant Agreement, and subject to the terms and conditions thereof, the previously outstanding 3.7 million warrants to acquire shares of this subsidiary were amended and restated to no longer be exercisable for shares of common stock of this subsidiary but instead be exercisable for an aggregate of approximately 8.3 million shares of Class B common stock (the “CMP Restated Warrants”). The CMP Restated Warrants expired by their terms on July 31, 2012. Prior to the expiration thereof, approximately 3.7 million CMP Restated Warrants were converted into approximately 8.2 million shares of Class B common stock.
	Equity Held in Reserve
	Pursuant to the agreement governing the Company's acquisition of Citadel Broadcasting Company ("Citadel") in 2011 (the "Citadel Merger"), warrants to purchase 2.4 million shares of the Company’s common stock were reserved for potential future issuance in connection with the settlement of certain remaining allowed, disputed or not reconciled claims related to Citadel's bankruptcy. As part of the June 2014 completion of proceedings related to the Citadel Bankruptcy, the 2.4 million shares were issued for $25.0 million from treasury stock. The equity held in reserve was included in additional paid-in-capital on the accompanying consolidated balance sheet at December 31, 2013.
	Company Warrants
	As a component of the Citadel Merger and the related financing transactions, the Company issued warrants to purchase an aggregate of 71.7 million shares of Class A common stock (the "Company Warrants") under a warrant agreement dated September 16, 2011 (the "Warrant Agreement"). The Company Warrants are exercisable at any time prior to June 3, 2030, at an exercise price of $0.01 per share. The exercise price of the Company Warrants is not subject to any anti-dilution protection, other than standard adjustments in the case of stock splits, dividends and the like. Pursuant to the terms and conditions of the Warrant Agreement, upon the request of a holder, the Company has the discretion to issue, upon exercise of the Company Warrants, shares of Class B common stock in lieu of an equal number of shares of Class A common stock and, upon request of a holder and at the Company’s discretion, the Company has the right to exchange such warrants to purchase an equivalent number of shares of Class B common stock for outstanding warrants to purchase shares of Class A common stock.
	Conversion of the Company Warrants is subject to compliance with applicable FCC regulations, and the Company Warrants are exercisable provided that ownership of the Company’s securities by the holder does not cause the Company to violate applicable FCC rules and regulations relating to foreign ownership of broadcasting licenses.
	Holders of Company Warrants are entitled to participate ratably in any distributions on the Company’s common stock on an as-exercised basis. No distribution will be made to holders of Company Warrants or common stock if (i) an FCC ruling, regulation or policy prohibits such distribution to holders of Company Warrants or (ii) the Company’s FCC counsel opines that such distribution is reasonably likely to cause (a) the Company to violate any applicable FCC rules or regulations or (b) any holder of Company Warrants to be deemed to hold an attributable interest in the Company.
	During the year ended December 31, 2014, approximately 15.8 million Company Warrants were converted into shares of Class A common stock. As of December 31, 2014, 1.4 million Company Warrants remained outstanding.
	Crestview Warrants
	Also on September 16, 2011, but pursuant to a separate warrant agreement, the Company issued warrants to purchase 7.8 million shares of Class A common stock with an exercise price, as adjusted to date, of $4.34 per share (the "Crestview Warrants"). The Crestview Warrants are exercisable until September 16, 2021, and the per share exercise price is subject to standard weighted average adjustments in the event that the Company issues additional shares of common stock or common stock derivatives for less than the fair market value per share, as defined in the Crestview Warrants, as of the date of such issuance. In addition, the number of shares of Class A common stock issuable upon exercise of the Crestview Warrants, and the exercise price of the Crestview Warrants, are subject to adjustment in the case of stock splits, dividends and the like. As of December 31, 2014, all 7.8 million Crestview Warrants remained outstanding.

Stock-Based Compensation Expense	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation Expense	Stock-Based Compensation Expense
	The Company uses the Black-Scholes option pricing model to estimate the fair value of stock options issued. The determination of the fair value of stock options on the date of grant is affected by the Company’s stock price, historical stock price volatility over the expected term of the awards, risk-free interest rates and expected dividends. With respect to restricted stock awards, the Company recognizes compensation expense over the vesting period equal to the grant date fair value of the shares awarded. To the extent non-vested restricted stock awards include performance or market conditions management examines the requisite service period to recognize the cost associated with the award on a case-by-case basis.
	Generally, the Company’s grants of stock options vest over four years and have a maximum contractual term of ten years. The Company estimates the volatility of its common stock by using a weighted average of historical stock price volatility over the expected term of the options. The Company bases the risk-free interest rate that it uses in its option pricing model on United States Treasury issues with terms similar to the expected term of the options. The Company does not anticipate paying any cash dividends on the class of stock subject to granted stock options in the foreseeable future and therefore uses an expected dividend yield of zero in the option pricing model. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from estimates. Stock-based compensation expense is recorded only for those awards that are expected to vest. All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards.
	On February 16, 2012, the Company granted 161,724 shares of time-vesting restricted Class A common stock, with an aggregate grant date fair value of $0.6 million, to the non-employee directors of the Company with a cliff vesting term of one year. In addition, on February 16, 2012, the Company granted time-vesting stock options to purchase 1.4 million shares of Class A common stock to certain Company employees, with an aggregate grant date fair value of $3.3 million. The options have an exercise price of $4.34 per share, with 30% of the awards having vested on each of September 16, 2012 and February 16, 2013, and 20% having vested on each of February 16, 2014 and February 16, 2015.
	On December 27, 2012, the Company issued stock options to an officer of the Company exercisable for 0.8 million shares of Class A common stock with an aggregate grant date fair value of $1.1 million. The options have an exercise price of $4.34 per share, and provide for vesting on each of the first four anniversaries of the date of grant, with 30% of the award vesting on each of the first two anniversaries thereof, and 20% of the award vesting on each of the next two anniversaries thereof.
	On May 9, 2013, the Company granted 168,540 shares of time-vesting restricted Class A common stock, with an aggregate grant date fair value of $0.6 million, to the non-employee directors of the Company with a cliff vesting term of one year.
	On May 22, 2014, the Company granted 93,312 shares of time-vesting restricted Class A common stock, with an aggregate grant date fair value of $0.6 million, to the non-employee directors of the Company with a cliff vesting term of one year.
	During 2013, the Company granted 8.3 million stock options with an aggregate grant date fair value of $32.4 million. The options range in exercise price from $4.34 to $5.92 per share, and provide for vesting on each of the first four anniversaries of the date of grant, with 30% of each award vesting on each of the first two anniversaries thereof, and 20% of each award vesting on each of the next two anniversaries thereof.
	During 2014, the Company granted 0.8 million stock options with an aggregate grant date fair value of $3.2 million. The options range in exercise price from $3.50 to $7.74 per share, and provide for vesting on each of the first four anniversaries of the date of grant, with 30% of each award vesting on each of the first two anniversaries thereof, and 20% of each award vesting on each of the next two anniversaries thereof.
	Stock-based compensation expense for these awards is recognized on a straight-line basis over each award’s vesting period.
	The total fair value of restricted stock awards that vested during the years ended December 31, 2014 and 2013 was $0.6 million and $1.6 million, respectively.
	For the years ended December 31, 2014, 2013 and 2012, the Company recognized approximately $17.6 million, $10.8 million and $11.9 million in non-cash stock-based compensation expense, respectively, related to equity awards. The associated tax benefits related to these non-cash stock-based compensation awards for the years ended December 31, 2014, 2013 and 2012 were $7.1 million, $4.1 million and $0.0 million, respectively.
	As of December 31, 2014, unrecognized stock-based compensation expense of approximately $25.6 million related to equity awards is expected to be recognized over a weighted average remaining life of 2.59 years. Unrecognized stock-based compensation expense for equity awards will be adjusted for future changes in estimated forfeitures.
	As of December 31, 2014, the total number of shares of common stock that remain authorized, reserved and available for issuance under any of the Company’s equity incentive plans was approximately 6.0 million, not including shares underlying outstanding grants. The Company is only authorized to make additional award grants under the 2011 Equity Incentive Plan.

	2011 Equity Incentive Plan
	The Board adopted the 2011 Equity Incentive Plan on July 8, 2011. Also, on July 8, 2011, stockholders holding a majority of the outstanding voting power of the Company, upon the recommendation of the Board, approved the 2011 Equity Incentive Plan.
	The 2011 Equity Incentive Plan authorizes the grant of equity-based compensation in the form of stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units (“RSUs”), performance shares, performance units, and other awards for the purpose of providing Cumulus Media’s non-employee directors, consultants, officers and other employees incentives and rewards for superior performance.
	The 2011 Equity Incentive Plan is administered by the Compensation Committee. The Compensation Committee may delegate its authority under the 2011 Equity Incentive Plan.
	Total awards under the 2011 Equity Incentive Plan are limited to 35,000,000 shares (the “Authorized Plan Aggregate”) of Class A common stock. The 2011 Equity Incentive Plan also provides that: (i) the aggregate number of shares of Class A common stock actually issued or transferred upon the exercise of incentive stock options (“ISOs”) will not exceed 17,500,000 shares; (ii) the number of shares of Class A common stock issued as restricted stock, RSUs, performance shares, performance units and other awards (after taking into account any forfeitures and cancellations) will not, during the term of the 2011 Equity Incentive Plan, in the aggregate exceed 12,000,000 shares of Class A common stock; (iii) no participant will be granted stock options or SARs, in the aggregate, for more than 11,500,000 shares of Class A common stock during any calendar year; (iv) no participant will be granted awards of restricted stock, RSUs, performance shares or other awards that are intended to qualify as “qualified performance-based compensation” under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), in the aggregate, for more than 3,000,000 shares of Class A common stock during any calendar year; and (v) no participant during any calendar year will be granted awards of performance units that are intended to qualify as “qualified performance-based compensation” under Section 162(m) of the Code, in the aggregate, for more than a maximum value of $5,000,000 as of their respective dates of grant.
	The 2011 Equity Incentive Plan provides that only shares with respect to awards that expire or are forfeited or canceled, or shares that were covered by an award the benefit of which is paid in cash instead of shares, will again be available for issuance under the 2011 Equity Incentive Plan. The following shares are not added back to the Authorized Plan Aggregate: (i) shares tendered in payment of a stock option exercise price; (ii) shares withheld by the Company to satisfy tax withholding obligations; and (iii) shares repurchased by the Company with stock option proceeds. Further, all shares covered by a SAR that is exercised and settled in shares, and whether or not all shares are actually issued to the participant upon exercise of the right, will be considered issued or transferred pursuant to the 2011 Equity Incentive Plan.
	The 2011 Equity Incentive Plan provides that generally: (i) stock options and SARs may not become exercisable by the passage of time sooner than one-third per year over three years except in the event of retirement, death or disability of a participant or in the event of a change in control (described below); (ii) stock options and SARs that become exercisable upon the achievement of Management Objectives (as defined below) cannot become exercisable sooner than one year from the date of grant except in the event of retirement, death or disability of a participant or in the event of a change in control; (iii) restricted stock and RSUs may not become unrestricted by the passage of time sooner than one-third per year over three years unless restrictions lapse sooner by virtue of retirement, death or disability of a participant or in the event of a change in control; (iv) the period of time within which Management Objectives relating to performance shares and performance units must be achieved will be a minimum of one year, subject to earlier lapse or modification by virtue of retirement, death or disability of a participant or in the event of a change in control; (v) restricted stock and RSUs that vest upon the achievement of Management Objectives cannot vest sooner than one year from the date of grant, but may be subject to earlier lapse or modification by virtue of retirement, death or disability of a participant or in the event of a change in control; and, (vi) as described below, a limited number of awards, however, including restricted stock and RSUs granted to non-employee directors, may be granted without regard to the above minimum vesting periods. Repricing of options and SARs is prohibited without stockholder approval under the 2011 Equity Incentive Plan.
	In general, a change in control will be deemed to have occurred if: (i) there is a consummation of a sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its subsidiaries taken as a whole to any person or group; (ii) a plan relating to the liquidation or dissolution of the Company is adopted; (iii) there is a consummation of any transaction (including, without limitation, any purchase, sale, acquisition, disposition, merger or consolidation) the result of which is that any person or group becomes the beneficial owner (excluding any options to purchase equity securities of the Company held by such person or group) of more than 50% of the aggregate voting power of all classes of capital stock of the Company having the right to elect directors under ordinary circumstances; or (iv) a majority of the members of the Board are not Continuing Directors. For purposes of this definition, a “Continuing Director” is, as of any date of determination, any member of the Board who (1) was a member of the Board on July 8, 2011 or (2) was nominated for election or elected to the Board with the approval of either two-thirds of the Continuing Directors who were members of the Board at the time of such nomination or election or two-thirds of those Company directors who were previously approved by Continuing Directors.
	The 2011 Equity Incentive Plan provides that dividends or other distributions on performance shares, restricted stock or RSUs that are earned or that have restrictions that lapse as a result of the achievement of Management Objectives will be deferred until and paid contingent upon the achievement of the applicable Management Objectives. The 2011 Equity Incentive Plan also provides that dividends and dividend equivalents will not be paid on stock options or SARs.
	The 2011 Equity Incentive Plan provides that no stock options or SARs will be granted with an exercise or base price less than the fair market value of the Class A common stock on the date of grant. The 2011 Equity Incentive Plan is designed to allow awards to qualify as qualified performance-based compensation under Section 162(m) of the Code.
	The following performance metrics may be used as “Management Objectives”: profits, cash flow, returns, working capital, profit margins, liquidity measures, sales growth, gross margin growth, cost initiative and stock price metrics, and strategic initiative key deliverable metrics.
	As of December 31, 2014, there were outstanding options to purchase a total of 26,090,400 shares of Class A common stock at exercise prices ranging from $2.75 to $7.74 per share under the 2011 Equity Incentive Plan, of which 9,357,840 shares are unvested and 16,732,560 shares are vested.

	Net noncurrent deferred tax liabilities	507,991				500,506
	Net deferred tax liabilities	$	464,143			$	457,408
	Deferred tax assets and liabilities are computed by applying the federal and state income tax rates in effect to the gross amounts of temporary differences and other tax attributes, such as net operating loss carry-forwards. In assessing if the deferred tax assets will be realized, the Company considers whether it is more likely than not that some or all of these deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which these deductible temporary differences reverse.
	For the years ended December 31, 2012 and 2011 the Company maintained a full valuation allowance on its net deferred tax assets exclusive of its deferred tax liability on its indefinite lived intangibles. During the year ended December 31, 2012, the Company reduced its valuation allowance from $201.2 million to $171.0 million. This change in valuation allowance of $30.2 million was recorded as a tax benefit to net income for the year and is primarily the result of an increase to future sources of taxable income available to recover the Company's deferred tax assets. During the year ended December 31, 2013, the valuation allowance was reduced by $154.3 million to $16.8 million. The reduction in valuation allowance was recorded as a deferred tax benefit during the year, of which $69.5 million relates to the change in judgment about the future realization of deferred tax assets available at the beginning of the year with the remainder related to the consumption of federal and state net operating losses; primarily the result of taxable income related to the sale of assets to Townsquare. The $16.8 million valuation allowance remaining at December 31, 2013 relates to the current inability to recover certain separate company state net operating losses. During the year ended December 31, 2014, the valuation allowance increased by $2.2 million to $19.0 million. This increase was recorded as deferred tax expense and is the result of the inability to utilize the benefit of current year net operating losses in certain jurisdictions.
	At December 31, 2014, Company has federal net operating loss carry forwards, which are available to offset future taxable income, of approximately $433.8 million which will expire in the years 2030 through 2032. At December 31, 2014, the Company has state net operating loss carry forwards available to offset future income of approximately $2.4 billion which will expire in the years 2017 through 2034. In addition to the federal and state net operating loss carry forwards noted above, approximately $1.5 million of net operating loss carry forwards relate to windfall tax benefits associated with the Company's equity based compensation plan that will benefit additional paid in capital when realized. The Company's policy is to treat these equity based net operating loss carry forwards as the last net operating loss carry forwards to be consumed.
	The Company records interest and penalties related to unrecognized tax benefits in current income tax expense. Of this amount, $0.5 million was recorded to expense in 2014. The total interest and penalties accrued as of December 31, 2014 is $6.2 million. The increase in accrued interest and penalty in 2014 of $2.1 million is the result of additional interest and penalties estimated to be due with respect to uncertain tax positions acquired in the WestwoodOne acquisition of $1.6 million plus the 2014 annual accrual of $0.5 million. The total unrecognized tax benefits and accrued interest and penalties at December 31, 2014 was $20.7 million. Of this total, $17.0 million represents the unrecognized tax benefits and accrued interest and penalties that, if recognized, would favorably affect the effective income tax rate in future periods. Of the $20.7 million total unrecognized tax benefits and accrued interest and penalties, $18.1 million relates to items which are not expected to change significantly within the next 12 months. Substantially all federal, state, local and foreign income tax returns have been closed for the tax years through 2010; however, the various tax jurisdictions may adjust the Company's net operating loss carry forwards. The following table reconciles unrecognized tax benefits during the relevant years:
	Balance at January 1, 2013		$	12,285
	Increases for tax positions related to the WestwoodOne acquisition		2,603
	Balance at December 31, 2013		$	14,888
	Increases for tax positions related to the WestwoodOne acquisition		(422		)
	Balance at December 31, 2014		$	14,466

Earnings Per Share [Abstract]
Earnings Per Share ("EPS")	Earnings Per Share (“EPS”)
	For all periods presented, the Company has disclosed basic and diluted earnings (loss) per common share utilizing the two-class method. Basic earnings (loss) per common share is calculated by dividing net income (loss) available to common shareholders by the weighted average number of shares of common stock outstanding during the period. In accordance with the terms of the Third Amended and Restated Charter, the Company allocates undistributed net income (loss) from continuing operations between each class of common stock on an equal basis after any allocations for preferred stock dividends.
	Non-vested restricted shares of Class A common stock and the Company Warrants are considered participating securities for purposes of calculating basic weighted average common shares outstanding in periods in which the Company records net income. Diluted earnings (loss) per share is computed in the same manner as basic earnings (loss) per share after assuming issuance of common stock for all potentially dilutive equivalent shares, which includes stock options and certain warrants to purchase common stock. Antidilutive instruments are not considered in this calculation. Under the two-class method, net income (loss) is allocated to common stock and participating securities to the extent that each security may share in earnings (loss), as if all of the earnings (loss) for the period had been distributed. Earnings (loss) are allocated to each participating security and common share equally, after deducting dividends declared or accretion on preferred stock.
	The following table sets forth the computation of basic and diluted earnings (loss) per common share for the years ended December 31, 2014, 2013 and 2012 (amounts in thousands, except per share data):

	The Company has non-cancelable operating leases, primarily for land, tower space, office-space, certain office equipment and vehicles. The operating leases generally contain renewal options for periods ranging from one to ten years and require the Company to pay all executory costs such as maintenance and insurance. Rental expense for operating leases was approximately $27.4 million, $22.6 million, and $25.9 million for the years ended December 31, 2014, 2013 and 2012, respectively.

	Effective December 31, 2009, the Company’s radio music license agreements with the two largest performance rights organizations, The American Society of Composers, Authors and Publishers (“ASCAP”) and Broadcast Music, Inc. (“BMI”), expired. In January 2010, the Radio Music License Committee (the “RMLC”), which negotiates music licensing fees for most of the radio industry with ASCAP and BMI, filed motions in the New York courts against these organizations on behalf of the radio industry, seeking interim fees and a determination of fair and reasonable industry-wide license fees. During 2010, the courts approved reduced interim fees for ASCAP and BMI. On January 27, 2012, the Federal District Court for the Southern District of New York approved a settlement between the RMLC and ASCAP concerning the fees payable covering the period January 1, 2010 through December 31, 2016. Included in the agreement is a $75.0 million industry fee credit against fees previously paid in 2010 and 2011, with such fees to be credited over the remaining period of the contract. The Company began recognizing the ASCAP credits as a reduction in direct operating expenses on January 1, 2012. On August 28, 2012, the Federal District Court for the Southern District of New York approved a settlement between the RMLC and BMI concerning the fees payable covering the period January 1, 2010 through December 31, 2016. Included in the agreement is a $70.5 million industry fee credit against fees previously paid in 2010 and 2011, with such fees immediately available to the industry.
	The radio broadcast industry’s principal ratings service is Nielsen Audio, which publishes surveys for domestic radio markets. Certain of the Company’s subsidiaries have agreements with Nielsen Audio under which they receive programming ratings materials in a majority of their respective markets. The remaining aggregate obligation under the agreements with Nielsen Audio is approximately $174.2 million and is expected to be paid in accordance with the agreements through December 2017.
	The Company engages Katz as its national advertising sales agent. The national advertising agency contract with Katz contains termination provisions that, if exercised by the Company during the term of the contract, would obligate the Company to pay a termination fee to Katz, calculated based upon a formula set forth in the contract.
	On September 13, 2013, the Company and Pulser entered into the Rdio Agreement, which provides that Cumulus will act as the exclusive promotional agent for Rdio ad products, including display, mobile, in-line audio, synced banners and other digital inventory that may become available from time to time. In exchange for $75 million of promotional commitments over five years, Cumulus will receive 15% of the equity interests of Pulser, with the opportunity to earn additional equity in the form of warrants based on the achievement of certain performance milestones over the term of the Rdio Agreement. The Company will record the equity received for services at fair value and will evaluate the investment for impairment in subsequent periods.
	The Company is committed under various contractual agreements to pay for broadcast rights that include news services and to pay for executives, talent, research, weather and other services.
	The Company from time to time enters into radio network contractual obligations to guarantee a minimum amount of revenue share to contractual counterparties on certain programming in future years. Generally, these guarantees are subject to decreases dependent on clearance targets achieved. As of December 31, 2014, the Company believes that it will meet such minimum obligations.
	On January 2, 2014 (the "Commencement Date”), Merlin Media, LLC (“Merlin”) and the Company entered into an LMA. Under this LMA, the Company is responsible for operating two FM radio stations in Chicago, Illinois, for monthly fees payable to Merlin of approximately $0.3 million, $0.4 million, $0.5 million and $0.6 million in the first, second, third and fourth years following the Commencement Date, respectively, in exchange for the Company retaining the operating profits from these radio stations.
	In connection therewith, the Company and Merlin also entered into an agreement pursuant to which the Company has the right to purchase these two FM radio stations until October 4, 2017, for an amount in cash equal to the greater of (i) $70.0 million minus the aggregate amount of monthly fees paid by the Company on or prior to the earlier of the closing date or the date that is four years after the Commencement Date; or (ii) $50.0 million, and Merlin has the right to require the Company to purchase these two FM radio stations at any time during a ten-day period commencing October 4, 2017 for $71.0 million, minus the aggregate amount of monthly fees paid by the Company on or prior to the earlier of the closing date or the date that is four years after the Commencement Date.
	The Company determined through its review of the requirements of ASC 810 that the Company is not the primary beneficiary of the LMA with Merlin, and, therefore consolidation of the stations is not required.
	On April 1, 2014, the Company initiated an exit plan for a lease due to a restructuring in connection with the acquisition of WestwoodOne (the "Exit Plan"), which includes charges related to terminated contract costs. In connection with the Exit Plan, the Company recorded restructuring costs of $5.2 million for the year ended December 31, 2014, which costs are included in corporate expenses in the consolidated statement of operations. As of December 31, 2014, liabilities related to the Exit Plan of $0.4 million were included in accounts payable and accrued expenses and are expected to be paid within one year and $4.3 million of non-current liabilities are included in other liabilities in the consolidated balance sheet. We anticipate no additional future charges for the Exit Plan other than true-ups to closed facilities lease charges and accretion expense.
	On April 25, 2014, the Company entered into an LMA with Universal Media Access, LLC “(Universal”) pursuant to which the Company is responsible for operating one FM radio station serving San Jose and San Francisco, California for a fixed fee to Universal of approximately $1.4 million each year for two years in exchange for the Company retaining the operating profits from this radio station.
	In connection therewith, the Company and Universal also entered into an agreement pursuant to which the Company has the right to purchase the radio station until April 5, 2016 for $14.8 million minus the aggregate amount of monthly LMA fees paid by the Company on or prior to the earlier of the closing date or the date that is 18 months after April 25, 2014. In addition, Universal has the right to require the Company to purchase the station at any time during a ten-day period commencing April 5, 2016 for $14.8 million, minus the aggregate amount of fees paid by the Company on or prior to the earlier of the closing date or the date that is two years after April 25, 2014.
	The Company determined through its review of the requirements of ASC 810 that the Company is not the primary beneficiary of the LMA with Universal, and, therefore consolidation of the station is not required.
	As described in Note 2, “Acquisitions and Dispositions,” the Company may be required to pay additional cash consideration in connection with the WFME Asset Exchange in New York and the Wise Brothers Acquisition. In addition, as a component of the Country Weekly Acquisition, the Company entered into an agreement with one of the sellers to collaborate on the production, publication and distribution of Country Weekly for a fee of $1.0 million for a period of 6 years from date of the Country Weekly Acquisition.
	Legal Proceedings
	We are currently party to, or a defendant in, various claims or lawsuits that are generally incidental to our business. We also expect that from time to time in the future we will be party to, or a defendant in, various claims or lawsuits that are generally incidental to our business. We expect that we will vigorously contest any such claims or lawsuits and believe that the ultimate resolution of any known claim or lawsuit will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

	At December 31, 2014, Cumulus (the "Parent Guarantor") and certain of its 100% owned subsidiaries (such subsidiaries, the “Subsidiary Guarantors”) provided guarantees of the obligations of Cumulus Holdings (the "Subsidiary Issuer") under the 7.75% Senior Notes. These guarantees are full and unconditional (subject to customary release provisions) as well as joint and several. Certain of the Subsidiary Guarantors may be subject to restrictions on their respective ability to distribute earnings to Cumulus Holdings or the Parent Guarantor. Not all of the subsidiaries of Cumulus and Cumulus Holdings guarantee the 7.75% Senior Notes (such non-guaranteeing subsidiaries, collectively, the “Subsidiary Non-guarantors”).
	The following tables present (i) condensed consolidating statements of operations for the years ended December 31, 2014, 2013 and 2012, (ii) condensed consolidating balance sheets as of December 31, 2014 and 2013, and (iii) condensed consolidating statements of cash flows for the years ended December 31, 2014, 2013, and 2012 of each of the Parent Guarantor, Cumulus Holdings, the Subsidiary Guarantors, and the Subsidiary Non-guarantors. These results have been adjusted for discontinued operations (see Note 3, "Discontinued Operations").
	Investments in consolidated subsidiaries are held primarily by the Parent Guarantor in the net assets of its subsidiaries and have been presented using the equity method of accounting. The “Eliminations” entries in the following tables primarily eliminate investments in subsidiaries and intercompany balances and transactions. The columnar presentations in the following tables are not consistent with the Company’s business groups; accordingly, this basis of presentation is not intended to present the Company’s financial condition, results of operations or cash flows on a consolidated basis.
	Reclassifications
	Certain account balances in the 2013 and 2012 periods have been reclassified to conform to classifications currently in use. In the accompanying unaudited condensed consolidating statements of operations the Company separately presents content costs and other direct operating expenses as operating expense categories. In certain of the Company's historical disclosures, those line items were presented on a combined basis within the direct operating expenses line item in the statement of operations. Content costs consist of all costs related to the licensing, acquisition and development of the Company's programming. Other direct operating expenses consist of expenses related to the distribution and monetization of the Company's content across its platform and overhead expenses. There were no other costs included in direct operating expenses in 2013 or 2012.

Description of Business, Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Description of Business	Description of Business
	Cumulus Media Inc. (and its consolidated subsidiaries, except as the context may otherwise require, “Cumulus,” “Cumulus Media,” “we,” “us,” “our,” or the “Company”) is a Delaware corporation, organized in 2002, and successor by merger to an Illinois corporation with the same name that had been organized in 1997.
Basis of Presentation	Basis of Presentation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain assets of the Company were sold during the year ended December 31, 2013 (see Note 2, “Acquisitions and Dispositions”). The results of operations associated with these assets have been separately reported, net of the related tax impact, for all periods presented in the consolidated statements of operations because the operations and cash flows generated by these assets have been eliminated from the Company’s consolidated results of operations as a result of the sale, and the Company no longer has continuing involvement in the operations of the stations associated with those assets after their disposal (see Note 3, “Discontinued Operations”).
Reclassifications	Reclassifications
	Certain account balances in the 2013 and 2012 periods have been reclassified to conform with classifications currently in use. In the accompanying consolidated statements of operations, the Company separately presents content costs and other direct operating expenses as operating expense categories. In certain of the Company's historical disclosures, those line items were presented on a combined basis within the direct operating expenses line item in the statement of operations. Content costs consist of all costs related to the licensing, acquisition and development of the Company's programming. Other direct operating expenses consist of expenses related to the distribution and monetization of the Company's content across its platform and overhead expenses. There were no other costs included in direct operating expenses in 2014, 2013 or 2012.
	These reclassifications had no effect on previously reported results of operations, retained earnings or cash flows.
Reportable Segment	Reportable Segment
	The Company operates in one reportable business segment, radio broadcasting, advertising and related services, for which segment disclosure is consistent with the management decision-making process that determines the allocation of resources and the measurement of performance. Below the reportable business segment, the Company has three reporting units (See Note 6, "Intangible Assets and Goodwill").
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to revenue recognition, bad debts, intangible assets, income taxes, stock-based compensation, contingencies, litigation, and purchase price allocation. The Company bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual amounts and results may differ materially from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents
	The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.
Accounts Receivable, Allowance for Doubtful Accounts and Concentration of Credit Risk	Accounts Receivable, Allowance for Doubtful Accounts and Concentration of Credit Risk
	Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on several factors including the length of time receivables are past due, trends and current economic factors. All balances are reviewed and evaluated quarterly on a consolidated basis. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers.
	In the opinion of management, credit risk with respect to accounts receivable is limited due to the large number of customers and the geographic diversification of the Company’s customer base. The Company performs ongoing credit evaluations of its customers and believes that adequate allowances for any uncollectible accounts receivable are maintained.
Assets Held for Sale, Property and Equipment	Assets Held for Sale
	During the year ended December 31, 2014, the Company entered into an agreement to sell certain land and buildings to a third party. The agreement is subject to various terms including a 60 day due diligence period. The carrying value of the identified assets have been classified as held for sale in the consolidated balance sheet at December 31, 2014. The estimated fair value of the land and buildings is in excess of the carrying value.
	Property and Equipment
	Property and equipment are stated at cost. Property and equipment acquired in business combinations accounted for under the purchase method of accounting are recorded at their estimated fair values on the date of acquisition. Equipment held under capital leases is stated at the present value of minimum future lease payments.
	Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the assets. Equipment held under capital leases and leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the asset or the remaining term of the lease. Depreciation of construction in progress is not recorded until the assets are placed into service.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets
	Long-lived assets, such as property and equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.
Intangible Assets and Goodwill	Intangible Assets and Goodwill
	The Company’s intangible assets are comprised of broadcast licenses, certain other intangible assets and goodwill. Goodwill is equal to the difference between the purchase price and the value assigned to the tangible and intangible assets acquired and liabilities assumed. Intangible assets and goodwill acquired in a business combination and determined to have an indefinite useful life, which include the Company’s broadcast licenses, are not amortized, but instead tested for impairment at least annually. Intangible assets with definite useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.
	In determining that the Company’s broadcast licenses qualified as indefinite lived intangibles, management considered a variety of factors including the Federal Communications Commission’s (“FCC”) historical record of renewing broadcast licenses, the cost to the Company of renewing such licenses, the relative stability and predictability of the radio industry and the relatively low level of capital investment required to maintain the physical plant of a radio station. The Company evaluates the recoverability of its indefinite-lived assets, which include broadcasting licenses and goodwill, using judgments and estimates. Future events may impact these judgments and estimates. If events or changes in circumstances were to indicate that an asset’s carrying value is not recoverable, a write-down of the asset would be recorded through a charge to operations.
Investments	Investments
	The Company follows Accounting Standards Codification (“ASC”) Topic 325-20, Cost Method Investments (“ASC 325-20”) to account for its ownership interest in noncontrolled entities. Under ASC 325-20, equity securities that do not have readily determinable fair values (i.e., non-marketable equity securities) and are not required to be accounted for under the equity method are typically carried at cost (i.e., cost method investments). Investments of this nature are initially recorded at cost. Income is recorded for dividends received that are distributed from net accumulated earnings of the noncontrolled entity subsequent to the date of investment. Dividends received in excess of earnings subsequent to the date of investment are considered a return of investment and are recorded as reductions in the cost of the investment. Investments are written down only when there is clear evidence that a decline in value that is other than temporary has occurred. During the year ended December 31, 2014, the Company sold one of its cost method investments for $13.0 million, recognizing a gain on sale of $3.2 million, which is included in other income (expense), net in the consolidated statement of operations.
Debt Issuance Costs	Debt Issuance Costs
	The costs related to the issuance of debt are capitalized and amortized to interest expense over the life of the related debt using the effective interest method.
Derivative Financial Instruments	Derivative Financial Instruments
	The Company recognizes all derivatives on the consolidated balance sheets at fair value. Fair value changes are recorded in income for any contracts not classified as qualifying hedging instruments.
Revenue Recognition	Revenue Recognition
	Revenue is derived primarily from the sale of commercial airtime to local and national advertisers. Revenue is recognized as commercials are broadcast. Revenues presented in the financial statements are reflected on a net basis, after the deduction of advertising agency fees by the advertising agencies, usually at a rate of 15.0%, which is the industry standard.
	In those instances in which we function as the principal in the transaction, the revenue and associated operating costs are presented on a gross basis. In those instances where we function as an agent or sales representative, our effective commission is presented as revenue with no corresponding operating expenses.
Advertising Costs	Advertising Costs
	Advertising costs are expensed as incurred.
Local Marketing Agreements	Local Marketing Agreements
	In certain circumstances, the Company may enter into a local marketing agreement (“LMA”) or time brokerage agreement with a FCC licensee of a radio station. In a typical LMA, the licensee of the station makes available, for a fee, airtime on its station to a party, which supplies programming to be broadcast on that airtime, and collects revenues from advertising aired during such programming. Revenues earned and fees incurred pursuant to LMAs or time brokerage agreements are recognized at their gross amounts in the accompanying consolidated statements of operations.
Stock-based Compensation Expense	Stock-based Compensation Expense
	Stock-based compensation expense recognized under ASC Topic 718, Compensation — Share-Based Payment (“ASC 718”), for the years ended December 31, 2014, 2013 and 2012, was $17.6 million, $10.8 million, and $11.9 million, respectively. Upon adopting ASC 718 for awards with service conditions, an election was made to recognize stock-based compensation expense on a straight-line basis over the requisite service period for the entire award. For stock options with service conditions only, the Company utilizes the Black-Scholes option pricing model to estimate the fair value of options issued. For restricted stock awards with service conditions, the Company utilizes the intrinsic value method. For restricted stock awards with performance conditions, the Company evaluates the probability of vesting of the awards in each reporting period and adjusts compensation cost based on this assessment. The fair value is based on the use of certain assumptions regarding a number of highly complex and subjective variables. If other assumptions are used, the results could differ.
Trade Transactions	Trade Transactions
	The Company provides commercial airtime in exchange for goods and services used principally for promotional, sales and other business activities. An asset and liability is recorded at the fair value of the goods or services received. Trade revenue is recorded and the liability is relieved when commercials are broadcast and trade expense is recorded and the asset relieved when goods or services are consumed. Trade valuation is based upon management’s estimate of the fair value of the products, supplies and services received.
Income Taxes	Income Taxes
	The Company uses the liability method of accounting for deferred income taxes. Deferred income taxes are recognized for all temporary differences between the tax and financial reporting bases of the Company’s assets and liabilities based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. A valuation allowance is recorded for a net deferred tax asset balance when it is more likely than not that the benefits of the tax asset will not be realized. The Company continues to assess the need for its deferred tax asset valuation allowance in the jurisdictions in which it operates. Any adjustment to the deferred tax asset valuation allowance is recorded in the income statement of the period that the adjustment is determined to be required. See Note 14, “Income Taxes” for further discussion.
Earnings per Share	Earnings per Share
	Basic income (loss) per share is computed on the basis of the weighted average number of common shares outstanding. The Company allocates undistributed net income (loss) from continuing operations between each class of common stock on an equal basis after any allocations for preferred stock dividends in accordance with the terms of the Company’s third amended and restated certificate of incorporation (the “Third Amended and Restated Charter”).
	Non-vested restricted shares of Class A common stock and Company Warrants (defined below) are considered participating securities for purposes of calculating basic weighted average common shares outstanding in periods in which the Company records net income. Diluted earnings per share is computed in the same manner as basic earnings per share after assuming the issuance of common stock for all potentially dilutive equivalent shares, which includes stock options and certain other outstanding warrants to purchase common stock. Antidilutive instruments are not considered in this calculation. Under the two-class method, net income is allocated to common stock and participating securities to the extent that each security may share in earnings, as if all of the earnings for the period had been distributed. Earnings are allocated to each participating security and common share equally, after deducting dividends declared or accreted on preferred stock.
Fair Values of Financial Instruments	Fair Values of Financial Instruments
	The carrying values of cash equivalents, accounts receivables, accounts payable, and accrued expenses approximate fair value due to the short term to maturity of these instruments (See Note 10, "Fair Value Measurements").
Accounting for National Advertising Agency Contract	Accounting for National Advertising Agency Contract
	The Company has engaged Katz Media Group, Inc. (“Katz”) as its national advertising sales agent. The Company’s contract with Katz has several economic elements that principally reduce the overall expected commission rate below the stated base rate. The Company estimates the overall expected commission rate over the entire contract period and applies that rate to commissionable revenue throughout the contract period with the goal of estimating and recording a stable commission rate over the life of the contract.
	The potential commission adjustments are estimated and combined in the consolidated balance sheets with the contractual termination liability. That liability is accreted to commission expense to effectuate the stable commission rate over the term of the Katz contract. Over the term of the contract with Katz, management updates its assessment of the effective commission expense attributable to national sales in an effort to record a consistent commission rate in each period.
	The Company’s accounting for and calculation of commission expense to be realized over the life of the Katz contract requires management to make estimates and judgments that affect reported amounts of commission expense in each period. Actual results in any period may differ from management’s estimates.
Variable Interest Entities	Variable Interest Entities
	The Company accounts for entities qualifying as variable interest entities (“VIEs”) in accordance with ASC Topic 810, Consolidation (“ASC 810”). VIEs are required to be consolidated by the primary beneficiary. The primary beneficiary is the entity that holds the majority of the beneficial interests in the VIE. A VIE is an entity for which the primary beneficiary’s interest in the entity can change with changes in factors other than the amount of investment in the entity. From time to time, the Company enters into LMAs in connection with pending acquisitions or dispositions of radio stations and the requirements of ASC 810 may apply, depending on the facts and circumstances related to each transaction.
Adoption of New Accounting Standards	Adoption of New Accounting Standards
	ASU 2013-04. In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-04, which provides guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements where the total obligation is fixed at the reporting date, and for which no specific guidance currently exists. The Company adopted this guidance effective January 1, 2014. The adoption of this guidance did not have an impact on the consolidated financial statements.
	ASU 2013-11. In July 2013, the FASB issued ASU 2013-11. The amendments in this ASU clarify when a liability related to an unrecognized tax benefit should be presented in the financial statements as a reduction to the related deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. The Company adopted this guidance effective January 1, 2014. The adoption of this guidance did not have an impact on the consolidated financial statements.
Recent Accounting Standards Updates	Recent Accounting Standards Updates
	ASU 2014-08. In April 2014, the FASB issued ASU 2014-08. Under this ASU, only disposals that represent a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. This ASU (1) expands the disclosure requirements for disposals that meet the definition of a discontinued operation, (2) requires entities to disclose information about disposals of individually significant components, (3) defines “discontinued operations” similarly to how it is defined under International Financial Reporting Standards ("IFRS") 5, and (4) requires entities to expand their disclosures about discontinued operations to include more information about assets, liabilities, income and expenses. In addition, this ASU will also require entities to disclose the pre-tax income attributable to a disposal of “an individually significant component of an entity that does not qualify for discontinued operations presentation in the financial statements.” The ASU is effective prospectively for all disposals (or classifications as held for sale) that occur within annual periods beginning on or after December 15, 2014 and interim periods within those years. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the consolidated financial statements.
	ASU 2014-09. In May 2014, the FASB issued ASU 2014-09. The amended guidance under this ASU outlines a single comprehensive revenue model for entities to use in accounting for revenue arising from contracts with customers. The guidance supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the single comprehensive revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” Entities have the option of using either a full retrospective or modified approach to adopt the guidance. The ASU is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016 (early adoption is not permitted). The Company is currently assessing the expected impact, if any, that this ASU will have on the consolidated financial statements.
	ASU 2014-15. In August 2014, the FASB issued ASU 2014-15. The amendments in this update provide guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. In doing so, the amendments should reduce diversity in the timing and content of footnote disclosures. The amendments in this ASU are effective for public and nonpublic entities for annual periods ending after December 15, 2016, and interim periods thereafter. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the consolidated financial statements.
	ASU 2015-01. In January 2015, the FASB issued ASU 2015-01. The amendments in this ASU eliminate the concept of an extraordinary item from GAAP. As a result, an entity will no longer be required to segregate extraordinary items from the results of ordinary operations, to separately present an extraordinary item on its income statement, net of tax, after income from continuing operations or to disclose income taxes and earnings-per-share data applicable to an extraordinary item. However, the ASU will still retain the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. The ASU will be effective for fiscal years beginning December 1, 2016 and subsequent interim periods. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the consolidated financial statements.
Acquisitions and Dispositions	Pamal Broadcasting Asset Purchase
	On January 17, 2013, the Company completed the acquisition of WMEZ-FM and WXBM-FM from Pamal Broadcasting Ltd. for a purchase price of $6.5 million (the "Pamal Broadcasting Asset Purchase"). The transaction was part of the Company’s ongoing efforts to focus on radio stations in larger markets and geographically strategic regional clusters.
	WestwoodOne Acquisition
	On December 12, 2013, Cumulus completed the acquisition of WestwoodOne, Inc. (formerly known as Dial Global, Inc., "WestwoodOne"), an independent, full-service radio network company offering news, sports, formats, prep services, talk and music programming, jingles and imaging, and special events, as well as national advertising sales representation (the "WestwoodOne Acquisition"). The WestwoodOne Acquisition added sports, news, talk, music and programming services content – enabling the Company to provide an even broader array of programming content to approximately 10,000 U.S. radio stations, other media platforms and international platforms. Content acquired through the WestwoodOne Acquisition included NFL, NCAA, NASCAR, Olympics, AP Radio News, NBC News and other popular programming.
	In connection with the WestwoodOne Acquisition, all of the issued and outstanding shares of capital stock of WestwoodOne were automatically canceled and converted into the right to receive an aggregate of approximately $45.0 million in cash, and WestwoodOne repaid all of its outstanding indebtedness. The payment of the purchase price to complete the WestwoodOne Acquisition (including the cash used to repay approximately $215.0 million of WestwoodOne’s outstanding indebtedness) was funded from cash on hand, which included $235.0 million in cash proceeds from the Townsquare Transaction (defined below). As a result of the WestwoodOne Acquisition, WestwoodOne became a wholly owned indirect subsidiary of the Company.
	2013 Acquisitions and Dispositions
	Green Bay Purchase
	On December 31, 2013, the Company completed the purchase of five radio stations in Green Bay, Wisconsin from Clear Channel for $17.6 million in cash (the "Green Bay Purchase"). The Company had been operating the stations under an LMA agreement with Clear Channel since April 10, 2009.
	Townsquare Transaction
	On November 14, 2013, the Company completed the sale to Townsquare Media, LLC (“Townsquare”) of 53 radio stations in 12 small and mid-sized markets for $235.0 million in cash and the swap with Townsquare of 15 radio stations in two small and mid-sized markets in exchange for five radio stations in Fresno, California (together, the "Townsquare Transaction"). The Company used the cash proceeds from the Townsquare Transaction to fund a portion of the purchase price payable to complete the WestwoodOne Acquisition.
	WFME Asset Exchange
	On January 8, 2013, the Company completed its previously announced asset exchange (the “WFME Asset Exchange”) with Family Stations, Inc., pursuant to which it exchanged its WDVY station in New York plus $40.0 million in cash for Family Stations’ WFME station in Newark, New Jersey. This asset exchange provided Cumulus with a radio station in the United States’ largest media market, for the national NASH entertainment brand based on the country music lifestyle. The total purchase price is subject to an increase of up to $10.0 million if certain future conditions are met as detailed in the purchase agreement.
Fair Value Measurements	The three levels of the fair value hierarchy to be applied to financial instruments when determining fair value are described below:
	Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the ability to access;
	Level 2 — Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities; and
	Level 3 — Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company’s financial assets and liabilities are measured at fair value on a recurring basis and non-financial assets and liabilities are measured at fair value on a non-recurring basis.

	-1	The Company’s only derivative financial instrument is the interest rate cap pursuant to which the Company pays a fixed interest rate on a $71.3 million notional amount of its term loans. The fair value of the interest rate cap is determined based on discounted cash flow analysis on the expected future cash flows using observable inputs, including interest rates and yield curves. Derivative valuations incorporate adjustments that are necessary to reflect the credit risk.
	-2	On September 13, 2013, the Company and Pulser Media, Inc. (the parent company of Rdio) ("Pulser"), entered into a five year strategic promotional partnership and sales arrangement (the "Rdio Agreement"). In exchange for $75 million of promotional commitments over five years, Cumulus will receive a 15% equity interest in Pulser, with the opportunity to earn additional equity, see Note 17, "Commitments and Contingencies". The fair value of the equity interest in Pulser was determined using inputs that are supported by little or no market activity (a Level 3 measurement). At December 31, 2014, the fair value of the equity interest in Pulser approximated its cost basis and the Company determined that the investment was not impaired.
	-3	The fair value of the contingent consideration was determined using inputs that are supported by little or no market activity (a Level 3 measurement). Contingent consideration represents the fair value of the additional cash consideration potentially payable as part of the WFME Asset Exchange and Wise Brothers Acquisition. See Note 2, “Acquisitions and Dispositions”.

[1]	On September 13, 2013, the Company and Pulser Media, Inc. (the parent company of Rdio) ("Pulser"), entered into a five year strategic promotional partnership and sales arrangement (the "Rdio Agreement"). In exchange for $75 million of promotional commitments over five years, Cumulus will receive a 15% equity interest in Pulser, with the opportunity to earn additional equity, see Note 17, "Commitments and Contingencies". The fair value of the equity interest in Pulser was determined using inputs that are supported by little or no market activity (a Level 3 measurement). At December 31, 2014, the fair value of the equity interest in Pulser approximated its cost basis and the Company determined that the investment was not impaired.
[2]	The Company’s only derivative financial instrument is the interest rate cap pursuant to which the Company pays a fixed interest rate on a $71.3 million notional amount of its term loans. The fair value of the interest rate cap is determined based on discounted cash flow analysis on the expected future cash flows using observable inputs, including interest rates and yield curves. Derivative valuations incorporate adjustments that are necessary to reflect the credit risk.
[3]	The fair value of the contingent consideration was determined using inputs that are supported by little or no market activity (a Level 3 measurement). Contingent consideration represents the fair value of the additional cash consideration potentially payable as part of the WFME Asset Exchange and Wise Brothers Acquisition. See Note 2, “Acquisitions and Dispositions”.
