Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of Presentation j2 Global, Inc., together with its subsidiaries ("j2 Global" or the "Company"), is a leading provider of Internet services. Through its Business Cloud Services Division, the Company provides cloud services to businesses of all sizes, from individuals to enterprises, and licenses its intellectual property ("IP") to third parties. In addition, the Business Cloud Services Division includes our j2 Cloud Connect, which is primarily focused on our number-based voice and fax services. The Digital Media Division specializes in the technology and gaming markets, reaching in-market buyers and influencers in both the consumer and business-to-business space. The accompanying interim condensed consolidated financial statements include the accounts of j2 Global and its direct and indirect wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with instructions for Form 10-Q and Article 10 of Regulation S-X issued by the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and note disclosures required by GAAP for complete financial statements although the Company believes that the disclosures made are adequate to make that information not misleading. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been reflected in these interim financial statements. It is suggested that these financial statements be read in conjunction with the audited financial statements and the related notes thereto for the year ended December 31, 2015 included in our Annual Report (Form 10-K) filed with the SEC on February 29, 2016. Accordingly, significant accounting policies and other disclosures normally provided have been omitted since such items are disclosed therein. The results of operations for this interim period are not necessarily indicative of the operating results for the full year or for any future period. Use of Estimates The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, including judgments about investment classifications, and the reported amounts of net revenue and expenses during the reporting period. We believe that our most significant estimates are those related to valuation and impairment of marketable securities, valuation of assets acquired and liabilities assumed in connection with business combinations, long-lived and intangible asset impairment, contingent consideration, income taxes and contingencies and allowances for doubtful accounts. On an ongoing basis, management evaluates its estimates based on historical experience and on various other factors that the Company believes to be reasonable under the circumstances. Actual results could materially differ from those estimates. Allowances for Doubtful Accounts j2 Global reserves for receivables it may not be able to collect. These reserves for the Company's Business Cloud Services segment are typically driven by the volume of credit card declines and past due invoices and are based on historical experience as well as an evaluation of current market conditions. These reserves for the Company's Digital Media segment are typically driven by past due invoices based on historical experience. On an ongoing basis, Management evaluates the adequacy of these reserves. Debt Issuance Costs and Debt Discount j2 Global capitalizes costs incurred with borrowing and issuance of debt securities and records debt issuance costs and discounts as a reduction to the debt amount. These costs and discounts are amortized and included in interest expense over the life of the borrowing or term of the credit facility using the effective interest method. Contingent Consideration j2 Global measures contingent earn-out liabilities in connection with acquisitions at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy (see Note 5 - Fair Value Measurements). The Company may use various valuation techniques depending on the terms and conditions of the contingent consideration including a Monte-Carlo simulation. This simulation uses a probability distribution for each significant input to produce hundreds or thousands of possible outcomes and the results are analyzed to determine probabilities of different outcomes occurring. Significant increases or decreases to these inputs in isolation would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and the amount paid will be recorded in earnings. The amount paid that is less than or equal to the liability on the acquisition date is reflected as cash used in financing activities in our consolidated statements of cash flows. Any amount paid in excess of the liability on the acquisition date is reflected as cash used in operating activities. j2 Global reviews and re-assess the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could be materially different from the initial estimates or prior quarterly amounts. Changes in the estimated fair value of our contingent earn-out liabilities are reported in operating income, except for the time component of the present value calculation which is reported in interest expense. Segment Reporting Accounting guidance establishes standards for the way that public business enterprises report information about operating segments in annual consolidated financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. Accounting guidance also establishes standards for related disclosures about products and services, geographic areas and major customers. The Company operates as two segments: (1) Business Cloud Services and (2) Digital Media. Reclassifications Certain prior year reported amounts have been reclassified to conform with the 2016 presentation.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, as a new Topic, Accounting Standards Codification (ASC) Topic 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize 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. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. This ASU must be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is continuing to evaluate the effect and methodology of adopting this new accounting guidance upon the Company's results of operations, cash flows and financial position. In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties About an Entity's Ability to Continue as a Going Concern. The new standard provides guidance around 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. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The adoption of this standard is not expected to have a material impact on our financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU modify how entities measure equity investments and present changes in the fair value of financial liabilities. Under the new guidance, entities will have to measure equity investments that do not result in consolidation and are not accounted under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicality exception. A practicality exception will apply to those equity investments that do not have a readily determinable fair value and do not qualify for the practical expedient to estimate fair value under ASC 820, Fair Value Measurements, and as such these investments may be measured at cost. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact of this ASU on our financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases. This ASU establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact of this ASU on our financial statements. In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815). This ASU is related to the embedded derivative analysis for debt instruments with contingent call or put options. This ASU clarifies that an exercise contingency does not need to be evaluated to determine whether it relates only to interest rates or credit risk. Instead, the contingent put or call option should be evaluated for possible bifurcation as a derivative in accordance with the four-step decision sequence detailed in FASB ASC 815-15, without regard to the nature of the exercise contingency. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on our financial statements. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606). This ASU is related to reporting revenue gross versus net, or principal versus agent considerations. This ASU is meant to clarify the guidance in ASU 2014-09, Revenue from Contracts with Customers, as it pertains to principal versus agent considerations. Specifically, the guidance addresses how entities should identify goods and services being provided to a customer, the unit of account for a principal versus agent assessment, how to evaluate whether a good or service is controlled before being transferred to a customer, and how to assess whether an entity controls services performed by another party. This ASU has the same effective date as the new revenue standard, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The Company is evaluating the effect and methodology of adopting this new accounting guidance upon the Company's results of operations, cash flows and financial position. In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718). This ASU is related to simplifications of employee share-based payment accounting. This pronouncement eliminates the APIC pool concept and requires that excess tax benefits and tax deficiencies be recorded in the income statement when awards are settled. The pronouncement also addresses simplifications related to statement of cash flows classification, accounting for forfeitures, and minimum statutory tax withholding requirements. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on our financial statements. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. This ASU is meant to clarify the guidance in FASB ASU 2014-09, Revenue from Contracts with Customers. Specifically, the guidance addresses an entity’s identification of its performance obligations in a contract, as well as an entity’s evaluation of the nature of its promise to grant a license of intellectual property and whether or not that revenue is recognized over time or at a point in time. This ASU has the same effective date as the new revenue standard, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The Company is evaluating the effect and methodology of adopting this new accounting guidance upon the Company's results of operations, cash flows and financial position. In May 2016, the FASB issued ASU 2016-11, Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting. This ASU rescinds SEC paragraphs pursuant to two SEC Staff Announcements at the March 3, 2016 Emerging Issues Task Force (EITF) meeting. Specifically, registrants should not rely on the following SEC Staff Observer comments upon adoption of Topic 606: 1) Revenue and Expense Recognition for Freight Services in Process, which is codified in paragraph 605-20-S99-2; 2) Accounting for Shipping and Handling Fees and Costs, which is codified in paragraph 605-45-S99-1; 3) Accounting for Consideration Given by a Vendor to a Customer (including Reseller of the Vendor's Products), which is codified in paragraph 605-50-S99-1; and 4) Accounting for Gas-Balancing Arrangements (i.e., use of the "entitlements method"), which is codified in paragraph 932-10-S99-5. This ASU becomes effective upon adoption of ASU 2014-09, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the impact of this ASU on our financial statements. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. This ASU does not change the core principle of the guidance in Topic 606. Instead, the amendments provide clarifying guidance in a few narrow areas and add some practical expedients to the guidance. This ASU has the same effective date as the new revenue standard, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the impact of the pending adoption of this new standard on our financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently evaluating the impact of this ASU on our financial statements.

Business Acquisition

Business Combinations [Abstract]
Business Acquisition	Business Acquisitions The Company uses acquisitions as a strategy to grow its customer base by increasing its presence in new and existing markets, expand and diversify its service offerings, enhance its technology, acquire skilled personnel and enter into other jurisdictions. The Company completed the following acquisitions during the first six months of fiscal 2016, paying the purchase price in cash in each transaction: (a) an asset purchase of VaultLogix, acquired on February 17, 2016, a Massachusetts-based provider of cloud data backup and storage for business clients; (b) a share purchase of the entire issued capital of CallStream Group Limited, acquired on March 3, 2016, a provider of cloud-based call management solutions to markets in the United Kingdom; (c) an asset purchase of Publicaster, acquired on April 1, 2016, a Maryland-based provider of email marketing services; (d) an asset purchase of SMTP, acquired on June 27, 2016, a Florida-based provider of cloud email services offering solutions ranging from sophisticated transactional email solutions to cost-effective Simple Mail Transfer Protocol ("SMTP") relay services; and (e) other immaterial acquisitions of online data backup, email marketing and digital media businesses. The condensed consolidated statement of income, since the date of each acquisition, and balance sheet, as of June 30, 2016 , reflect the results of operations of all 2016 acquisitions. For the six months ended June 30, 2016 , these acquisitions contributed $10.3 million to the Company's revenues. Net income contributed by these acquisitions was not separately identifiable due to j2 Global's integration activities and is impracticable to provide. Total consideration for these transactions was $78.7 million , net of cash acquired and assumed liabilities and is subject to certain post-closing adjustments which may increase or decrease the final consideration paid. The following table summarizes the allocation of the purchase consideration for these acquisitions (in thousands): Assets and Liabilities Valuation Accounts receivable $ 977 Property and equipment 1,114 Other assets 512 Software 2,257 Trade names 3,762 Customer relationships 29,295 Other intangibles 607 Goodwill 43,542 Other accrued liabilities (1,236 ) Deferred revenue (374 ) Deferred tax liability (1,747 ) Total $ 78,709 During the first six months of 2016, the purchase price accounting has been finalized for the following acquisitions: (i) LiveVault, (ii) Salesify, (iii) CallStream Group Limited and (iv) other immaterial fax, online data backup and digital media businesses. The initial accounting for all other acquisitions is incomplete and subject to change, which may be significant. j2 Global has recorded provisional amounts which may be based upon past acquisitions with similar attributes for certain intangible assets (including trade names, software and customer relationships), preliminary acquisition date working capital and related tax items. During the six months ended June 30, 2016 , the Company recorded adjustments to prior period acquisitions due to the finalization of purchase accounting in the Business Cloud Services segment which resulted in a net increase in goodwill in the amount of $0.6 million . In addition, the Company recorded adjustments to the initial working capital related to prior period acquisitions and updated the purchase accounting of Offers.com in the Digital Media segment, which resulted in a net decrease in goodwill in the amount of $(5.1) million with a corresponding increase in trade names, net and other purchased intangibles, net (See Note 6 - Goodwill and Intangible Assets). Such adjustments had an immaterial impact to the amortization expense within the Condensed Consolidated Statement of Income for the six months ended June 30, 2016 . Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired and represents intangible assets that do not qualify for separate recognition. Goodwill recognized associated with these acquisitions during the six months ended June 30, 2016 is $43.5 million , of which $31.7 million is expected to be deductible for income tax purposes.

Investments [Abstract]
Investments	Investments Short-term investments consist generally of corporate and governmental debt securities and certificates of deposits, which are stated at fair market value. Realized gains and losses of short and long-term investments are recorded using the specific identification method, average cost method or other method, as appropriate. The following table summarizes j2 Global’s debt securities designated as available-for-sale, classified by the contractual maturity date of the security (in thousands): June 30, December 31, 2015 Due within 1 year $ 34,719 $ 56,940 Due within more than 1 year but less than 5 years 42,233 78,248 Due within more than 5 years but less than 10 years — — Due 10 years or after 304 315 Total $ 77,256 $ 135,503 The following table summarizes the Company’s investments (in thousands): June 30, December 31, 2015 Available-for-sale $ 93,390 $ 158,158 Certificates of deposit 62 60 Total $ 93,452 $ 158,218 The following table summarizes the gross unrealized gains and losses and fair values for the Company's investments classified as available-for-sale investments as of June 30, 2016 and December 31, 2015 aggregated by major security type (in thousands): Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value June 30, 2016 Corporate debt securities $ 51,299 $ 273 $ (2 ) $ 51,570 Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies 19,213 14 (2 ) 19,225 Debt securities issued by states of the United States and political subdivisions of the states 6,493 11 (43 ) 6,461 Equity securities 12,612 3,522 — 16,134 Total $ 89,617 $ 3,820 $ (47 ) $ 93,390 December 31, 2015 Corporate debt securities $ 88,852 $ 110 $ (213 ) $ 88,749 Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies 40,715 — (63 ) 40,652 Debt securities issued by states of the United States and political subdivisions of the states 6,111 2 (10 ) 6,103 Equity securities 18,536 4,118 — 22,654 Total $ 154,214 $ 4,230 $ (286 ) $ 158,158 At June 30, 2016 and December 31, 2015, corporate and governmental debt securities, which have fixed interest rates, and equity securities were recorded as available-for-sale. There have been no significant changes in the maturity dates and average interest rates for the Company's investment portfolio and debt obligations subsequent to June 30, 2016 . At June 30, 2016 , the Company's available-for-sale securities are carried at fair value, with the unrealized gains and losses reported as a component of stockholders' equity. Recognition and Measurement of Other-Than-Temporary Impairment j2 Global regularly reviews and evaluates each investment that has an unrealized loss. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. Unrealized losses that are determined to be temporary in nature are recorded, net of tax, in accumulated other comprehensive income for available-for-sale securities. Regardless of the classification of the securities, the Company has assessed each position for impairment. Factors considered in determining whether a loss is temporary include: • the length of time and the extent to which fair value has been below cost; • the severity of the impairment; • the cause of the impairment and the financial condition and near-term prospects of the issuer; • activity in the market of the issuer which may indicate adverse credit conditions; and • the Company's ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery. j2 Global's review for impairment generally entails: • identification and evaluation of investments that have indications of possible impairment; • analysis of individual investments that have fair values less than amortized cost, including consideration of the length of time the investment has been in an unrealized loss position and the expected recovery period; • discussion of evidential matter, including an evaluation of factors or triggers that could cause individual investments to qualify as having an other-than-temporary impairment and those that would not support an other-than-temporary impairment; • documentation of the results of these analyses, as required under business policies; and • information provided by third-party valuation experts. For these securities, a critical component of the evaluation for other-than-temporary impairments is the identification of credit impairment, where management does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the security. Credit impairment is assessed using a combination of a discounted cash flow model that estimates the cash flows on the underlying securities and a market comparables method, where the security is valued based upon indications from the secondary market of what discounts buyers demand when purchasing similar securities. The cash flow model incorporates actual cash flows from the securities through the current period and then projects the remaining cash flows using relevant interest rate curves over the remaining term. These cash flows are discounted using a number of assumptions, some of which include prevailing implied credit risk premiums, incremental credit spreads and illiquidity risk premiums, among others. Securities that have been identified as other-than-temporarily impaired are written down to their current fair value. For debt securities that are intended to be sold or that management believes it more-likely-than-not that will be required to sell prior to recovery, the full impairment is recognized immediately in earnings. For available-for-sale securities that management has no intent to sell and believes that it more-likely-than-not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the rest of the fair value impairment is recognized in other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security. The following tables present gross unrealized losses and fair values for those investments that were in an unrealized loss position as of June 30, 2016 and December 31, 2015 , aggregated by investment category and the length of time that individual securities have been in a continuous loss position (in thousands): As of June 30, 2016 Less than 12 Months 12 Months or Greater Total Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Corporate debt securities $ 3,786 $ (2 ) $ — $ — $ 3,786 $ (2 ) Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies 1,248 (2 ) — — 1,248 (2 ) Debt securities issued by states of the United States and political subdivisions of the states 1,681 (43 ) — — 1,681 (43 ) Total $ 6,715 $ (47 ) $ — $ — $ 6,715 $ (47 ) As of December 31, 2015 Less than 12 Months 12 Months or Greater Total Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Corporate debt securities $ 74,807 $ (212 ) $ 1,000 $ (1 ) $ 75,807 $ (213 ) Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies 38,004 (62 ) 649 (1 ) 38,653 (63 ) Debt securities issued by states of the United States and political subdivisions of the states 4,189 (10 ) — — 4,189 (10 ) Total $ 117,000 $ (284 ) $ 1,649 $ (2 ) $ 118,649 $ (286 ) As of June 30, 2016 and December 31, 2015 , we did not recognize any other-than-temporary impairment losses.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Measurements j2 Global complies with the provisions of ASC 820, which defines fair value, provides a framework for measuring fair value and expands the disclosures required for fair value measurements of financial and non-financial assets and liabilities. ASC 820 clarifies that the fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: l Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. l Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. l Level 3 – Unobservable inputs which are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company's money market funds and its marketable equity securities are classified within Level 1. The Company values these Level 1 investments using quoted market prices. The Company's debt investments, time deposits and commercial paper, all of which have counterparties with high credit ratings, are classified within Level 2. The Company values these Level 2 investments based on quoted market prices or model-driven valuations using significant inputs derived from or corroborated by observable market data. The fair value of the Convertible Notes (See Note 7 - Long-Term Debt) is determined using recent quoted market prices or dealer quotes for such securities, which are Level 1 inputs. The fair value of the Senior Notes (See Note 7 - Long-Term Debt) is determined using quoted market prices or dealer quotes for instruments with similar maturities and other terms and credit ratings, which are Level 2 inputs. The fair value of long-term debt at June 30, 2016 and December 31, 2015 was $726.4 million and $790.5 million , respectively. In addition, the Convertible Notes contain terms that may require the Company to pay contingent interest on the Convertible Notes which is accounted for as a derivative with fair value adjustments being recorded to interest expense. This derivative is fair valued using a binomial lattice convertible bond pricing model using historical and implied market information, which are Level 2 inputs. The Company classifies its contingent consideration liability in connection with the acquisitions of Ookla and Salesify within Level 3 because factors used to develop the estimated fair value are unobservable inputs, such as volatility and market risks, and are not supported by market activity. The fair value of the contingent consideration liability was determined using option based approaches. This methodology was utilized because the distribution of payments is not symmetric and amounts are only payable upon certain earnings before interest, tax, depreciation and amortization ("EBITDA") thresholds being reached. Such valuation approach included the Monte-Carlo simulation for the contingency since the financial metric driving the payments is path dependent. Significant increases or decreases in either of the inputs noted above in isolation would result in a significantly lower or higher fair value of measurement. The following tables present the fair values of the Company's financial assets or liabilities that are measured at fair value on a recurring basis (in thousands): June 30, 2016 Level 1 Level 2 Level 3 Fair Value Assets: Cash equivalents: Money market and other funds $ 46,177 $ — $ — $ 46,177 Time deposits — 1,177 — 1,177 Certificates of deposit — 62 — 62 Equity securities 16,134 — — 16,134 Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies — 19,225 — 19,225 Debt securities issued by states of the U.S. and political subdivisions of the states — 6,461 — 6,461 Corporate debt securities — 51,570 — 51,570 Total assets measured at fair value $ 62,311 $ 78,495 $ — $ 140,806 Liabilities: Contingent consideration $ — $ — $ 15,400 $ 15,400 Contingent interest derivative — 1,450 — 1,450 Total liabilities measured at fair value $ — $ 1,450 $ 15,400 $ 16,850 December 31, 2015 Level 1 Level 2 Level 3 Fair Value Assets: Cash equivalents: Money market and other funds $ 46,867 $ — $ — $ 46,867 Time deposits — 3,004 — 3,004 Certificates of deposit — 60 — 60 Equity securities 22,654 — — 22,654 Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies — 40,652 — 40,652 Debt securities issued by states of the U.S. and political subdivisions of the states — 6,103 — 6,103 Corporate debt securities — 88,749 — 88,749 Total assets measured at fair value $ 69,521 $ 138,568 $ — $ 208,089 Liabilities: Contingent consideration $ — $ — $ 30,600 $ 30,600 Contingent interest derivative — 1,450 — 1,450 Total liabilities measured at fair value $ — $ 1,450 $ 30,600 $ 32,050 At the end of each reporting period, management reviews the inputs to the fair value measurements of financial and non-financial assets and liabilities to determine when transfers between levels are deemed to have occurred. For the six months ended June 30, 2016 , there were no transfers that have occurred between levels. The following table presents a reconciliation of the Company's Level 3 financial assets or liabilities that are measured at fair value on a recurring basis (in thousands): Level 3 Affected line item in the Statement of Income Balance as of January 1, 2016 $ 30,600 Total fair value adjustments reported in earnings 2,800 General and administrative Contingent consideration payments (18,000 ) Not applicable Balance as of June 30, 2016 $ 15,400 In connection with the acquisition of Ookla, on December 1, 2014, contingent consideration of up to an aggregate of $40.0 million may be payable upon achieving certain future income thresholds and had a fair value of $8.0 million and $25.0 million at June 30, 2016 and December 31, 2015 , respectively. Due to the Company's achievement of certain earnings targets for the year ended December 31, 2015, $20.0 million ( $17.0 million of contingent consideration and $3.0 million of compensation) was paid during the first quarter 2016 in connection with this acquisition. In connection with the acquisition of Salesify, on September 17, 2015, contingent consideration of up to an aggregate of $17.0 million may be payable upon achieving certain future income thresholds and had a fair value of $7.4 million and $5.6 million at June 30, 2016 and December 31, 2015 , respectively. Due to the Company's achievement of certain earnings targets for the year ended December 31, 2015, $1.0 million of contingent consideration was paid during the second quarter 2016 in connection with this acquisition. The contingent consideration associated with both of these acquisitions has been reclassified to current liabilities, excluding $2.2 million which remains as other long-term liability on the consolidated balance sheet at June 30, 2016 . During the six months ended June 30, 2016 , the Company recorded an increase in the fair value of the contingent consideration of $2.8 million and reported such increase in general and administrative expenses. The following table presents a reconciliation of the Company's derivative instruments (in thousands): Amount Affected line item in the Statement of Income Derivative Liabilities: Level 2: Balance as of January 1, 2016 $ 1,450 Total fair value adjustments reported in earnings — Balance as of June 30, 2016 $ 1,450 Losses associated with other-than-temporary impairments are recorded as a component of other income (expenses). Gains and losses not associated with other-than-temporary impairments are recorded as a component of other comprehensive income.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill And Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Intangible assets resulting from the acquisitions of entities accounted for using the acquisition method of accounting are recorded at the estimated fair value of the assets acquired. Identifiable intangible assets are comprised of purchased customer relationships, trademarks and trade names, developed technologies and other intangible assets. The fair values of these identified intangible assets are based upon expected future cash flows or income, which take into consideration certain assumptions such as customer turnover, trade names and patent lives. These determinations are primarily based upon the Company's historical experience and expected benefit of each intangible asset. If it is determined that such assumptions are not accurate, then the resulting change will impact the fair value of the intangible asset. Identifiable intangible assets are amortized over the period of estimated economic benefit, which ranges from one to 20 years. The changes in carrying amounts of goodwill for the six months ended June 30, 2016 are as follows (in thousands): Business Cloud Services Digital Media Consolidated Balance as of January 1, 2016 $ 502,718 $ 304,943 $ 807,661 Goodwill acquired (Note 3) 43,542 — 43,542 Purchase accounting adjustments (1) 612 (5,130 ) (4,518 ) Foreign exchange translation (5,624 ) (115 ) (5,739 ) Balance as of June 30, 2016 $ 541,248 $ 299,698 $ 840,946 (1) Purchase accounting adjustments relate to adjustments to goodwill in connection with prior year business acquisitions (See Note 3 - Business Acquisitions). Intangible Assets with Indefinite Lives: Intangible assets are summarized as of June 30, 2016 and December 31, 2015 as follows (in thousands): June 30, December 31, Trade name $ 27,379 $ 27,379 Other 5,432 5,432 Total $ 32,811 $ 32,811 Intangible Assets Subject to Amortization: As of June 30, 2016 , intangible assets subject to amortization relate primarily to the following (in thousands): Weighted-Average Amortization Period Historical Cost Accumulated Amortization Net Trade names 12.0 years $ 125,738 $ 32,439 $ 93,299 Patent and patent licenses 8.2 years 64,515 48,597 15,918 Customer relationships (1) 9.9 years 340,387 150,007 190,380 Other purchased intangibles 4.6 years 35,060 23,222 11,838 Total $ 565,700 $ 254,265 $ 311,435 (1) Historically, the Company has amortized its customer relationship assets in a pattern that best reflects the pace in which the asset's benefits are consumed. This pattern results in a substantial majority of the amortization expense being recognized in the first 4 to 5 years, despite the overall life of the asset. As of December 31, 2015 , intangible assets subject to amortization relate primarily to the following (in thousands): Weighted-Average Amortization Period Historical Cost Accumulated Amortization Net Trade names 12.0 years $ 117,753 $ 26,167 $ 91,586 Patent and patent licenses 8.3 years 64,258 45,417 18,841 Customer relationships (1) 9.4 years 313,909 116,590 197,319 Other purchased intangibles 4.2 years 33,088 21,004 12,084 Total $ 529,008 $ 209,178 $ 319,830 (1) Historically, the Company has amortized its customer relationship assets in a pattern that best reflects the pace in which the asset's benefits are consumed. This pattern results in a substantial majority of the amortization expense being recognized in the first 4 to 5 years, despite the overall life of the asset. Amortization expense, included in general and administrative expense, approximated $24.8 million and $17.6 million for the three month periods ended June 30, 2016 and 2015 , respectively, and $45.8 million and $34.6 million for the six month periods ended June 30, 2016 and 2015 , respectively. Amortization expense is estimated to approximate $109.2 million , $66.4 million , $43.4 million , $29.1 million and $22.3 million for fiscal years 2016 through 2020 , respectively, and $86.9 million thereafter through the duration of the amortization period.

Long-term Debt, Unclassified [Abstract]
Debt Disclosure [Text Block]	Long-Term Debt 8.0% Senior Notes On July 26, 2012 , the Company's subsidiary issued in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended, $250 million aggregate principal amount of 8.0% senior unsecured notes (the "Senior Notes") due August 1, 2020 . j2 Cloud Services, Inc. received proceeds of $245 million in cash, net of initial purchaser's discounts and commissions of $5 million . The net proceeds were available for general corporate purposes, including acquisitions. Interest is payable semi-annually on February 1 and August 1 of each year. j2 Cloud Services, Inc. has the option to call the Senior Notes in whole or in part after August 1, 2016 , subject to certain premiums as defined in the indenture governing the Senior Notes plus accrued and unpaid interest. Upon a change in control, the holders may put the Senior Notes at 101% of the principal amount of the Senior Notes plus accrued and unpaid interest, if any, to the repurchase date. In connection with the issuance of the Convertible Notes (defined below), j2 Global, Inc. unconditionally guaranteed, on an unsecured basis, the obligations of j2 Cloud Services, Inc. under the Senior Notes. The indenture governing the Senior Notes contains certain restrictive and other covenants applicable to j2 Cloud Services, Inc. and subsidiaries designated as restricted subsidiaries including, but not limited to, limitations on debt and disqualified or preferred stock, restricted payments, liens, sale and leaseback transactions, dividends and other payment restrictions, asset sales and transactions with affiliates. Restricted payments are applicable only if j2 Cloud Services, Inc. and subsidiaries designated as restricted subsidiaries has a pro forma leverage ratio of greater than 1.75 to 1.0. In addition, if such leverage ratio is in excess of 1.75 to 1.0, restricted payments are permitted up to $50 million. As of June 30, 2016 , j2 Cloud Services, Inc. was in compliance with all such covenants. Violation of these covenants could result in a default which could result in the acceleration of outstanding amounts if such default is not cured or waived within the time periods outlined in the indenture. As of June 30, 2016 and December 31, 2015 , the estimated fair value of the Senior Notes was approximately $273.9 million and $262.2 million , respectively, and was based on the quoted market prices of debt instruments with similar terms, credit rating and maturities of the Senior Notes which are Level 2 inputs (see Note 5 - Fair Value Measurements). 3.25% Convertible Notes On June 10, 2014 , j2 Global issued $402.5 million aggregate principal amount of 3.25% convertible senior notes due June 15, 2029 (the "Convertible Notes"). j2 Global received proceeds of $391.4 million in cash, net of underwriters' discounts and commissions. The net proceeds were available for general corporate purposes. The Convertible Notes bear interest at a rate of 3.25% per annum, payable semiannually in arrears on June 15 and December 15 of each year. Beginning with the six-month interest period commencing on June 15, 2021, the Company must pay contingent interest on the Convertible Notes during any six-month interest period if the trading price per $1,000 principal amount of the Convertible Notes for each of the five trading days immediately preceding the first day of such interest period equals or exceeds $1,300. Any contingent interest payable on the Convertible Notes will be in addition to the regular interest payable on the Convertible Notes. Holders may surrender their Convertible Notes for conversion at any time prior to the close of business on the business day immediately preceding the maturity date only if one or more of the following conditions is satisfied: (i) during any calendar quarter commencing after the calendar quarter ending on September 30, 2014 (and only during such calendar quarter), if the closing sale price of j2 Global common stock for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the calendar quarter immediately preceding the calendar quarter in which the conversion occurs is more than 130% of the applicable conversion price of the Convertible Notes on each such trading day; (ii) during the five consecutive business day period following any ten consecutive trading day period in which the trading price for the Convertible Notes for each such trading day was less than 98% of the product of (a) the closing sale price of j2 Global common stock on each such trading day and (b) the applicable conversion rate on each such trading day; (iii) if j2 Global calls any or all of the Convertible Notes for redemption, at any time prior to the close of business on the business day prior to the redemption date; (iv) upon the occurrence of specified corporate events; or (v) during either the period beginning on, and including, March 15, 2021 and ending on, but excluding, June 20, 2021 or the period beginning on, and including, March 15, 2029 and ending on, but excluding, the maturity date. j2 Global will settle conversions of Convertible Notes by paying or delivering, as the case may be, cash, shares of j2 Global common stock or a combination thereof at j2 Global's election. The Company currently intends to satisfy its conversion obligation by paying and delivering a combination of cash and shares of the Company's common stock, where cash will be used to settle each $1,000 of principal and the remainder, if any, will be settled via the Company's common stock. As of June 30, 2016 , the conversion rate is 14.4750 shares of j2 Global common stock for each $1,000 principal amount of Convertible Notes, which represents a conversion price of approximately $69.08 per share of j2 Global common stock. The conversion rate is subject to adjustment for certain events as set forth in the indenture governing the Convertible Notes, but will not be adjusted for accrued interest. In addition, following certain corporate events that occur on or prior to June 20, 2021, j2 Global will increase the conversion rate for a holder that elects to convert its Convertible Notes in connection with such a corporate event. j2 Global may not redeem the Convertible Notes prior to June 20, 2021. On or after June 20, 2021, j2 Global may redeem for cash all or part of the Convertible Notes at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Convertible Notes. Holders have the right to require j2 Global to repurchase for cash all or part of their Convertible Notes on each of June 15, 2021 and June 15, 2024 at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the relevant repurchase date. In addition, if a fundamental change, as defined in the indenture governing the Convertible Notes, occurs prior to the maturity date, holders may require j2 Global to repurchase for cash all or part of their Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. The Convertible Notes are the Company's general senior unsecured obligations and rank: (i) senior in right of payment to any of the Company's future indebtedness that is expressly subordinated in right of payment to the Convertible Notes; (ii) equal in right of payment to the Company's existing and future unsecured indebtedness that is not so subordinated, including in respect of j2 Global's guarantee of the obligations of our subsidiary, j2 Cloud Services, Inc., with respect to its outstanding Senior Notes; (iii) effectively junior in right of payment to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness; and (iv) structurally junior to all existing and future indebtedness (including trade payables) incurred by the Company's subsidiaries. Accounting for the Convertible Notes In accordance with ASC 470-20, Debt with Conversion and Other Options, convertible debt that can be settled for cash is required to be separated into the liability and equity component at issuance, with each component assigned a value. The value assigned to the liability component is the estimated fair value, as of the issuance date, of similar debt without the conversion feature. The difference between the cash proceeds and estimated fair value of the liability component, representing the value of the conversion premium assigned to the equity component, is recorded as a debt discount on the issuance date. This debt discount is amortized to interest expense using the effective interest method over the period from the issuance date through the first stated repurchase date on June 15, 2021. j2 Global estimated the borrowing rates of similar debt without the conversion feature at origination to be 5.79% for the Convertible Notes and determined the debt discount to be $59.0 million . As a result, a conversion premium after tax of $37.7 million was recorded in additional paid-in capital. The aggregate debt discount is amortized as interest expense over the period from the issuance date through the first stated repurchase date on June 15, 2021, which management believes is the expected life of the Convertible Notes using an interest rate of 5.81% . As of June 30, 2016 , the remaining period over which the unamortized debt discount will be amortized is 5.0 years . The Convertible Notes are carried at face value less any unamortized debt discount and debt issuance costs. The fair value of the Convertible Notes at each balance sheet date is determined based on recent quoted market prices or dealer quotes for the Convertible Notes, which are Level 1 inputs (see Note 5 - Fair Value Measurements). If such information is not available, the fair value is determined using cash-flow models of the scheduled payments discounted at market interest rates for comparable debt without the conversion feature. As of June 30, 2016 and December 31, 2015 , the estimated fair value of the Convertible Notes was approximately $452.5 million and $528.3 million , respectively.

Commitments And Contingencies	Commitments and Contingencies Litigation From time-to-time, j2 Global and its affiliates are involved in litigation and other disputes or regulatory inquiries that arise in the ordinary course of business. Any claims or regulatory actions against j2 Global and its affiliates, whether meritorious or not, could be time consuming and costly, and could divert significant operational resources. The outcomes of such matters are subject to inherent uncertainties, carrying the potential for unfavorable rulings that could include monetary damages and injunctive relief. On February 17, 2011, Emmanuel Pantelakis ("Pantelakis") filed suit against a j2 Global affiliate in the Ontario Superior Court of Justice (No. 11-50673), alleging that the j2 Global affiliate breached a contract relating to Pantelakis's use of the Campaigner ® service. The j2 Global affiliate filed a responsive pleading on March 23, 2011 and responses to undertakings on July 16, 2012. On November 6, 2012, Pantelakis filed a second amended statement of claim, reframing his lawsuit as a negligence action. The j2 Global affiliate filed an amended statement of defense on April 8, 2013. Discovery is ongoing. On January 17, 2013, the Commissioner of the Massachusetts Department of Revenue ("Commissioner") issued a notice of assessment to a j2 Global affiliate for sales and use tax for the period of July 1, 2003 through December 31, 2011. On July 22, 2014, the Commissioner denied the j2 Global affiliate's application for abatement. On September 18, 2014, the j2 Global affiliate petitioned the Massachusetts Appellate Tax Board for abatement of the tax asserted in the notice of assessment (No. C325426). A trial was held on December 16, 2015. The Massachusetts Appellate Tax Board has not yet rendered its decision. On January 18, 2013, Paldo Sign and Display Co. ("Paldo") filed an amended complaint adding two j2 Global affiliates and a former employee as additional defendants in an existing putative class action pending in the U.S. District Court for the Northern District of Illinois ("Northern District of Illinois") (No. 1:13-cv-01896). The amended complaint alleged violations of the Telephone Consumer Protection Act ("TCPA"), the Illinois Consumer Fraud and Deceptive Business Practices Act ("ICFA"), and common law conversion, arising from an indirect customer's alleged use of a j2 Global affiliate's systems to send unsolicited facsimile transmissions. The j2 Global affiliates filed a motion to dismiss the ICFA and conversion claims, which was granted. The Northern District of Illinois also dismissed the former employee for lack of personal jurisdiction. On August 23, 2013, a second plaintiff, Sabon, Inc. ("Sabon"), was added. On March 7, 2016, the j2 Global affiliates moved for summary judgment on all remaining claims. The summary judgment motions are pending. On August 28, 2013, Phyllis A. Huster ("Huster") filed suit in the Northern District of Illinois (No. 1:13-cv-06143) against two j2 Global affiliates and three other parties for correction of inventorship for nine j2 Global patents. Huster seeks, among other things, a declaration that she was an inventor of the patents-in-suit, an order directing the U.S. Patent & Trademark Office to substitute or add her as an inventor, and payment of at least half of defendants' earnings from licensing the patents-in-suit. On September 19, 2014, the Northern District of Illinois granted the defendants' motion to dismiss for improper venue and transferred the case to the U.S. District Court for the Northern District of Georgia ("Northern District of Georgia") (No. 1:14-cv-03304). Huster filed an amended complaint on February 11, 2015, which she corrected on February 12, 2015. The corrected amended complaint added various common law claims. On November 12, 2015, the Northern District of Georgia dismissed all claims against the j2 Global affiliates. On January 28, 2016, all remaining claims were dismissed on summary judgment. Huster filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit ("Federal Circuit") on February 26, 2016 (No. 16-1639). The appeal is pending. On October 16, 2013, a j2 Global affiliate entered an appearance as a plaintiff in a multi-district litigation pending in the Northern District of Illinois (No. 1:12-cv-06286). In this litigation, Unified Messaging Solutions, LLC ("UMS"), a company with rights to assert certain patents owned by the j2 Global affiliate, has asserted five j2 Global patents against a number of defendants. While claims against some defendants have been settled, other defendants have filed counterclaims for, among other things, non-infringement, unenforceability, and invalidity of the patents-in-suit. On December 20, 2013, the Northern District of Illinois issued a claim construction opinion and, on June 13, 2014, entered a final judgment of non-infringement for the remaining defendants based on that claim construction. UMS and the j2 Global affiliate filed a notice of appeal to the Federal Circuit on June 27, 2014 (No. 14-1611). The appeal is pending. On June 23, 2014, Andre Free-Vychine ("Free-Vychine") filed a putative class action against two j2 Global affiliates in the Superior Court for the State of California, County of Los Angeles ("Los Angeles Superior Court") (No. BC549422). The complaint alleged two California statutory violations relating to late fees levied in certain eVoice® accounts. Free-Vychine sought, among other things, damages and injunctive relief on behalf of himself and a purported nationwide class of similarly situated persons. On August 26, 2014, Law Enforcement Officers, Inc. ("LEO") and IV Pit Stop, Inc. ("IV Pit Stop") filed a separate putative class action against the same j2 Global affiliates in Los Angeles Superior Court (No. BC555721). The complaint alleged three California statutory violations, negligence, breach of the implied covenant of good faith and fair dealing, and various other common law claims relating to late fees levied on any of the j2 Global affiliates' customers, including those with eVoice® and Onebox® accounts. LEO and IV Pit Stop sought, among other things, damages and injunctive relief on behalf of themselves and a purported nationwide class of similarly situated persons. On September 29, 2014, the Los Angeles Superior Court related and consolidated both cases for discovery purposes. On March 13, 2015, a third amended complaint was filed in the case brought by LEO, which no longer included IV Pit Stop as a plaintiff but added Christopher Dancel ("Dancel") as a plaintiff. On June 26, 2015, the case filed by Free-Vychine was dismissed pursuant to a settlement agreement. On October 7, 2015, the parties in the case brought by LEO and Dancel reached a tentative class-based settlement that remains subject to court approval. j2 Global does not believe, based on current knowledge, that the foregoing legal proceedings or claims, after giving effect to existing reserves, are likely to have a material adverse effect on the Company's consolidated financial position, results of operations, or cash flows. However, depending on the amount and the timing, an unfavorable resolution of some or all of these matters could have a material affect on j2 Global's consolidated financial position, results of operations, or cash flows in a particular period. The Company has not accrued for loss contingencies relating to these legal proceedings because unfavorable outcomes are not considered probable by management. The Company has not accrued for any material loss contingencies relating to these legal proceedings because unfavorable outcomes are not considered probable by management. Non-Income Related Taxes As a provider of cloud services for business, the Company does not provide telecommunications services. Thus, it believes that its business and its users (by using the Company's services) are generally not subject to various telecommunication taxes. Moreover, the Company generally does not believe that its business and its users (by using the Company's services) are subject to other indirect taxes, such as sales and use tax, business tax and gross receipt tax. However, several state and municipal taxing authorities have challenged these beliefs and have and may continue to audit and assess the Company's business and operations with respect to telecommunications and other indirect taxes. On February 24, 2016, President Obama signed into law H.R. 644, the "Trade Facilitation and Trade Enforcement Act of 2015", which included a provision to permanently ban state and local authorities from imposing access or discriminatory taxes on the Internet. The new law allows "grandfathered" states and local authorities to continue their existing taxes on Internet access through June 2020. The Company is currently under audit for indirect taxes in several states and municipalities. On February 27, 2013, the Office of Finance for the City of Los Angeles (the "Los Angeles Office of Finance") issued assessments to a j2 Global affiliate for business and communications taxes for the period of January 1, 2009 through December 31, 2012. On September 11, 2014, the Los Angeles Office of Finance issued revised assessments to a j2 Global affiliate increasing such affiliate's liability to the City of Los Angeles. On April 30, 2015, the Los Angeles Office of Finance Board of Review denied the j2 Global affiliate's request to abate the assessments. The j2 Global affiliate paid the assessments and requested the abatement of penalties associated with the assessments. In addition, the j2 Global affiliate is currently working with the Office of the City Attorney of the City of Los Angeles to obtain a refund of the entire amount paid. For other jurisdictions, the Company currently has no reserves established for these matters, as the Company has determined that the liability is not probable and estimable. However, it is reasonably possible that such a liability could be incurred, which would result in additional expense, which could materially impact our financial results.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's tax provision for interim periods is determined using an estimate of the Company's annual effective tax rate. Each quarter the Company updates its estimated annual effective tax rate and, if the estimate changes, makes a cumulative adjustment. j2 Global's annual effective tax rate is normally lower than the 35% U.S. federal statutory rate and applicable apportioned state tax rates primarily due to anticipated earnings of the Company's subsidiaries outside of the U.S. in jurisdictions where the Company's effective tax rate is lower than in the U.S. The Company's effective tax rate was 30.9% and 0.5% for the three months ended June 30, 2016 and 2015 , respectively and 30.6% and 13.3% for the six months ended June 30, 2016 and 2015, respectively. j2 Global does not provide for U.S. income taxes on the undistributed earnings of the Company’s foreign operations because the Company intends to permanently reinvest such earnings in foreign jurisdictions and any determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable. Income before income taxes included income from domestic operations of $40.3 million and $28.2 million for the six months ended June 30, 2016 and 2015 , respectively, and income from foreign operations of $51.5 million and $41.9 million for the six months ended June 30, 2016 and 2015 , respectively. As of June 30, 2016 and December 31, 2015 , the Company had $40.4 million and $35.9 million , respectively, in liabilities for uncertain income tax positions. Accrued interest and penalties related to unrecognized tax benefits are recognized in income tax expense on the Company's consolidated statement of income. Cash paid for income taxes net of refunds received was $25.0 million and $26.9 million for the six months ended June 30, 2016 and 2015 , respectively. Certain taxes are prepaid during the year and included within prepaid expenses and other current assets on the consolidated balance sheet. The Company's prepaid taxes were $9.4 million and $11.6 million at June 30, 2016 and December 31, 2015 , respectively. Income Tax Audits : In November, 2015, the U.S. Internal Revenue Service ("IRS") began its income tax audit of the Company's 2012 and 2013 tax years. In March 2016, the IRS expanded its income tax audit to include the Company's 2014 tax year. j 2 Global is under income tax audit by the California Franchise Tax Board (the "FTB") for its tax years 2012 and 2013. The FTB, however, has agreed to suspend its audit for 2012 and 2013 pending the outcome of the IRS audit for such tax years. The Company is under income tax audit by the New York State Department of Taxation and Finance for tax years 2011 through 2013. j2 Global was under income tax audit by the New York City Department of Finance ("NYC") for its tax years 2009 through 2011. In February 2016, j2 Global settled its NYC audit for approximately $26,000 . It is reasonably possible that these audits may conclude in the next 12 months and that the uncertain tax positions the Company has recorded in relation to these tax years may change compared to the liabilities recorded for these periods. If the recorded uncertain tax positions are inadequate to cover the associated tax liabilities, the Company would be required to record additional tax expense in the relevant period, which could be material. If the recorded uncertain tax positions are adequate to cover the associated tax liabilities, the Company would be required to record any excess as reduction in tax expense in the relevant period, which could be material. However, it is not currently possible to estimate the amount, if any, of such change.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Options And Employee Stock Purchase Plan	Stock Options and Employee Stock Purchase Plan j2 Global's share-based compensation plans include the Second Amended and Restated 1997 Stock Option Plan (the "1997 Plan"), 2007 Stock Plan (the "2007 Plan"), 2015 Stock Option Plan (the "2015 Plan") and 2001 Employee Stock Purchase Plan (the "Purchase Plan"). Each plan is described below. The 1997 Plan terminated in 2007. A total of 12,000,000 shares of common stock were authorized to be used for 1997 Plan purposes. An additional 840,000 shares were authorized for issuance upon exercise of options granted outside the 1997 Plan. As of June 30, 2016 , 45,498 shares underlying options and zero shares of restricted stock were outstanding under the 1997 Plan, all of which continue to be governed by the 1997 Plan. The 2007 Plan provides for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units and other share-based awards. 4,500,000 shares of common stock are authorized to be used for 2007 Plan purposes. Options under the 2007 Plan may be granted at exercise prices determined by the Board of Directors, provided that the exercise prices shall not be less than the fair market value of j2 Global's common stock on the date of grant for incentive stock options and not less than 85% of the fair market value of j2 Global's common stock on the date of grant for non-statutory stock options. As of June 30, 2016 , 378,170 shares underlying options and 32,590 shares of restricted stock were outstanding under the 2007 Plan. The 2015 Plan provides for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance share units and other share-based awards and is intended as a successor plan to the 2007 Stock Plan since no further grants will be made under the 2007 Stock Plan. 4,200,000 shares of common stock are authorized to be used for 2015 Plan purposes. Options under the 2015 Plan may be granted at exercise prices determined by the Board of Directors, provided that the exercise prices shall not be less than the higher of the par value or 100% of the fair market value of j2 Global's common stock subject to the option on the date the option is granted. As of June 30, 2016 , 62,000 shares underlying options and 12,750 shares of restricted stock units were outstanding under the 2015 Plan. All stock option grants are approved by "outside directors" within the meaning of Internal Revenue Code Section 162(m). Stock Options The following table represents stock option activity for the six months ended June 30, 2016 : Number of Shares Weighted- Weighted-Average Aggregate Outstanding at January 1, 2016 566,428 $ 29.74 Granted — — Exercised (71,058 ) 26.38 Canceled (9,700 ) 26.92 Outstanding at June 30, 2016 485,670 $ 30.29 4.0 $ 16,228,340 Exercisable at June 30, 2016 421,570 $ 26.00 3.4 $ 15,721,070 Vested and expected to vest at June 30, 2016 471,653 $ 29.29 3.9 $ 16,185,217 The total intrinsic values of options exercised during the six months ended June 30, 2016 and 2015 were $2.5 million and $5.6 million , respectively. The Company recognized $0.2 million and $0.5 million of compensation expense for the six months ended June 30, 2016 and 2015, respectively, related to stock options. As of June 30, 2016 and December 31, 2015 , unrecognized stock compensation related to non-vested stock options granted under each of the share-based compensation plans approximated $0.8 million and $1.1 million , respectively. Unrecognized stock compensation expense related to non-vested stock options granted under these plans is expected to be recognized ratably over a weighted-average period of 3.2 years (i.e., the remaining requisite service period). Fair Value Disclosure j2 Global uses the Black-Scholes option pricing model to calculate the fair value of each option grant. The expected volatility is based on historical volatility of the Company's common stock. The Company estimates the expected term based upon the historical exercise behavior of our employees. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a term equal to the expected term of the option assumed at the date of grant. The Company uses an annualized dividend yield based upon the per share dividends declared by its Board of Directors. Estimated forfeiture rates were 12.33% and 13.42% as of June 30, 2016 and 2015 , respectively. Restricted Stock and Restricted Stock Units j2 Global has awarded restricted stock and restricted stock units to its Board of Directors and senior staff pursuant to certain share-based compensation plans. Compensation expense resulting from restricted stock and restricted unit grants is measured at fair value on the date of grant and is recognized as share-based compensation expense over the applicable vesting period. Beginning in fiscal year 2012, vesting periods are approximately one year for awards to members of the Company's Board of Directors and five years for senior staff (excluding market-based awards discussed below). Restricted Stock - Awards with Market Conditions In May 2016, certain key employees were granted market-based restricted stock awards. The market-based awards have vesting conditions that are based on specified stock price targets of the Company's common stock. Market conditions were factored into the grant date fair value using a Monte Carlo valuation model, which utilized multiple input variables to determine the probability of the Company achieving the specified stock price targets with a 20 day lookback (trading days). Stock-based compensation expense related to an award with a market condition will be recognized over the requisite service period using the graded-vesting method regardless of whether the market condition is satisfied, provided that the requisite service period has been completed. During the six months ended June 30, 2016 and 2015, the Company awarded 106,780 and zero market-based restricted stock awards, respectively. The per share weighted average grant-date fair values of the market-based restricted stock awards granted during the six months ended June 30, 2016 were $44.67 . There were no market-based restricted stock awards granted during 2015. The weighted-average fair values of market-based restricted stock awards granted have been estimated utilizing the following assumptions: June 30, 2016 Underlying stock price at valuation date $ 63.73 Expected volatility 29.8 % Risk-free interest rate 1.51 % Restricted stock award activity for the six months ended June 30, 2016 is set forth below: Shares Weighted-Average Grant-Date Fair Value Nonvested at January 1, 2016 704,804 $ 39.08 Granted 256,064 37.07 Vested (120,915 ) 46.09 Canceled (21,500 ) 68.71 Nonvested at June 30, 2016 818,453 $ 36.64 Restricted stock unit award activity for the six months ended June 30, 2016 is set forth below: Number of Weighted-Average Aggregate Outstanding at January 1, 2016 56,245 Granted 5,250 Vested (8,755 ) Canceled (7,400 ) Outstanding at June 30, 2016 45,340 1.8 $ 2,864,128 Vested and expected to vest at June 30, 2016 36,329 1.6 $ 2,294,908 The Company recognized $6.0 million and $5.7 million of compensation expense for the six months ended June 30, 2016 and 2015, respectively, related to restricted stock and restricted stock units. As of June 30, 2016 and December 31, 2015 , the Company had unrecognized share-based compensation cost of approximately $42.3 million and $34.5 million , respectively, associated with these awards. This cost is expected to be recognized over a weighted-average period of 3.4 years for awards and 3.0 years for units. Employee Stock Purchase Plan The Purchase Plan provides for the issuance of a maximum of two million shares of the Company's common stock. Under the Purchase Plan, eligible employees can have up to 15% of their earnings withheld, up to certain maximums, to be used to purchase shares of j2 Global's common stock at certain plan-defined dates. The price of the common stock purchased under the Purchase Plan for the offering periods is equal to 95% of the fair market value of the common stock at the end of the offering period. For the six months ended June 30, 2016 and 2015 , 1,920 and 2,104 shares were purchased under the plan, respectively. Cash received upon the issuance of common stock under the Purchase Plan was $123,000 and $126,000 for the six months ended June 30, 2016 and 2015 , respectively. As of June 30, 2016 , 1,628,524 shares were available under the Purchase Plan for future issuance.

Basis Of Presentation (Policy)

Basis Of Presentation (Policy)	6 Months Ended
	Jun. 30, 2016
Accounting Policies [Abstract]
Use Of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, including judgments about investment classifications, and the reported amounts of net revenue and expenses during the reporting period. We believe that our most significant estimates are those related to valuation and impairment of marketable securities, valuation of assets acquired and liabilities assumed in connection with business combinations, long-lived and intangible asset impairment, contingent consideration, income taxes and contingencies and allowances for doubtful accounts. On an ongoing basis, management evaluates its estimates based on historical experience and on various other factors that the Company believes to be reasonable under the circumstances. Actual results could materially differ from those estimates.
Allowances For Doubtful Accounts	Allowances for Doubtful Accounts j2 Global reserves for receivables it may not be able to collect. These reserves for the Company's Business Cloud Services segment are typically driven by the volume of credit card declines and past due invoices and are based on historical experience as well as an evaluation of current market conditions. These reserves for the Company's Digital Media segment are typically driven by past due invoices based on historical experience. On an ongoing basis, Management evaluates the adequacy of these reserves.
Debt	Debt Issuance Costs and Debt Discount j2 Global capitalizes costs incurred with borrowing and issuance of debt securities and records debt issuance costs and discounts as a reduction to the debt amount. These costs and discounts are amortized and included in interest expense over the life of the borrowing or term of the credit facility using the effective interest method.
Business Combinations	Contingent Consideration j2 Global measures contingent earn-out liabilities in connection with acquisitions at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy (see Note 5 - Fair Value Measurements). The Company may use various valuation techniques depending on the terms and conditions of the contingent consideration including a Monte-Carlo simulation. This simulation uses a probability distribution for each significant input to produce hundreds or thousands of possible outcomes and the results are analyzed to determine probabilities of different outcomes occurring. Significant increases or decreases to these inputs in isolation would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and the amount paid will be recorded in earnings. The amount paid that is less than or equal to the liability on the acquisition date is reflected as cash used in financing activities in our consolidated statements of cash flows. Any amount paid in excess of the liability on the acquisition date is reflected as cash used in operating activities. j2 Global reviews and re-assess the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could be materially different from the initial estimates or prior quarterly amounts. Changes in the estimated fair value of our contingent earn-out liabilities are reported in operating income, except for the time component of the present value calculation which is reported in interest expense.
Segment Reporting	Segment Reporting Accounting guidance establishes standards for the way that public business enterprises report information about operating segments in annual consolidated financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. Accounting guidance also establishes standards for related disclosures about products and services, geographic areas and major customers. The Company operates as two segments: (1) Business Cloud Services and (2) Digital Media.
Comparability of Prior Year Financial Data	Reclassifications Certain prior year reported amounts have been reclassified to conform with the 2016 presentation.
