Accordingly, they do not include certain information and disclosures required for complete financial statements. The preparation of financial statements in conformity with U.S. GAAP requires us to make judgments, assumptions and estimates that affect the amounts reported and disclosed. Actual results could differ from these estimates and assumptions. The consolidated results for interim periods are not necessarily indicative of results for the full year and should be read in conjunction with our 2014 Annual Report on Form 10-K. In the opinion of management, these unaudited Consolidated Financial Statements include all adjustments, consisting only of normal and recurring adjustments necessary for a fair statement of the information for each period contained therein. Certain reclassifications have been made to prior-period financial statements to conform to the current-period presentation. |

| Acquisitions [Abstract] | |
| Business Combination Disclosure [Text Block] | Acquisitions We continue to evaluate strategic opportunities to expand our industry expertise, strengthen our position in high-growth and key strategic geographical markets and industry sectors, advance technological capabilities and improve operational efficiency through both acquisitions and increased ownership interests in current investments. Our acquisitions typically provide for an initial payment at the time of closing and additional contingent purchase price payments based on the future performance of the acquired entity. We have entered into agreements that may require us to purchase additional equity interests in certain consolidated and unconsolidated subsidiaries. The amounts at which we record these transactions in our financial statements are based on estimates of the future financial performance of the acquired entity, the timing of the exercise of these rights, foreign currency exchange rates and other factors. During the first nine months of 2015 , we completed two acquisitions, including a full-service digital agency in the UK. Of our two acquisitions, one was included in the Integrated Agency Networks (“IAN”) operating segment, and one was included in the Constituency Management Group ("CMG") operating segment. During the first nine months of 2015 , we recorded approximately $14.0 of goodwill and intangible assets related to our acquisitions. During the first nine months of 2014 , we completed six acquisitions, consisting of a global digital agency, a full-service digital agency in the United States, a healthcare agency in the United Kingdom, a digital public relations agency based in Sweden, a digital and traditional creative agency in Germany and a search marketing agency based in the Netherlands. Of our six acquisitions, four were included in the IAN operating segment, and two were included in the CMG operating segment. During the first nine months of 2014 , we recorded approximately $137.0 of goodwill and intangible assets related to these acquisitions. The results of operations of our acquired companies were included in our consolidated results from the closing date of each acquisition. Details of cash paid for current and prior years' acquisitions are listed below. Nine months ended 2015 2014 Cost of investment: current-year acquisitions $ 8.3 $ 87.2 Cost of investment: prior-year acquisitions 31.8 13.3 Less: net cash acquired (2.4 ) (24.9 ) Total cost of investment 37.7 75.6 Operating expense 1 17.6 1.8 Total cash paid for acquisitions 2 $ 55.3 $ 77.4 1 Represents cash payments made that were either in excess of the initial value of contingent payments or contingent upon the future employment of the former owners of the acquired companies and are recorded in the operating section of the Consolidated Statements of Cash Flows. 2 Of the total cash paid for acquisitions, $31.8 and $12.7 for the nine months ended September 30, 2015 , and 2014 , respectively, are classified under the financing section of the unaudited Consolidated Statements of Cash Flows as acquisition-related payments. These amounts relate to deferred payments and increases in our ownership interest for prior acquisitions. $5.9 and $62.9 for the nine months ended September 30, 2015 , and 2014 , respectively, are classified under the investing section of the unaudited Consolidated Statements of Cash Flows, as acquisitions, net of cash acquired. These amounts relate to initial payments for new transactions. Many of our acquisitions also include provisions under which the noncontrolling equity owners may require us to purchase additional interests in a subsidiary at their discretion. The following table presents changes in our redeemable noncontrolling interests. Nine months ended 2015 2014 Balance at beginning of period $ 257.4 $ 249.1 Change in related noncontrolling interests balance (9.4 ) (6.7 ) Changes in redemption value of redeemable noncontrolling interests: Additions 0.5 22.0 Redemptions and other (24.4 ) (4.5 ) Redemption value adjustments 1 2.4 (4.6 ) Balance at end of period $ 226.5 $ 255.3 1 In each reporting period, redeemable noncontrolling interests are reported at their estimated redemption value, but not less than their initial fair value. Any adjustment to the redemption value above initial value prior to exercise will also impact retained earnings or additional paid-in capital, except adjustments as a result of currency translation. |

(Losses) Gains on Sales of Businesses and Investments – During the three months ended September 30, 2015 , we recognized losses on the sales of businesses on completed dispositions within both our IAN and CMG segments and the classification of certain assets as held for sale within our IAN segment. As of September 30, 2015, assets held for sale, included in other current assets, was $6.9, primarily consisting of cash and accounts receivable, and liabilities held for sale, included in accrued liabilities, was $17.6, primarily consisting of accounts payable and accrued liabilities, related to sales of businesses expected to be completed within the next twelve months. Vendor Discounts and Credit Adjustments – In connection with the liabilities related to vendor discounts and credits established as part of the restatement we presented in our 2004 Annual Report on Form 10-K, these adjustments reflect the reversal of certain of these liabilities primarily where the statute of limitations has lapsed, or as a result of differences resulting from settlements with clients or vendors. Other Income (Expense), net – During the nine months ended September 30, 2015 , we recorded a gain related to swap contracts within our Corporate and other segment. During the nine months ended September 30, 2014 , we recorded a loss related to an other-than-temporary impairment of an investment in the Asia Pacific region within our IAN segment. |

| Share Repurchase Program | Share Repurchase Program In February 2015, our Board of Directors (the "Board") authorized a new share repurchase program to repurchase from time to time up to $300.0 , excluding fees, of our common stock (the "2015 Share Repurchase Program"), which was in addition to the remaining amount available to be repurchased from the $300.0 authorization made by the Board in February 2014 (the "2014 Share Repurchase Program"). We may effect such repurchases through open market purchases, trading plans established in accordance with SEC rules, derivative transactions or other means. We expect to continue to repurchase our common stock in future periods, although the timing and amount of the repurchases will depend on market conditions and other funding requirements. The following table presents our share repurchase activity under our share repurchase programs for the nine months ended September 30, 2015 and 2014 . Nine months ended 2015 2014 Number of shares repurchased 8.5 8.3 Aggregate cost, including fees $ 172.3 $ 148.1 Average price per share, including fees $ 20.36 $ 17.91 We fully utilized the 2014 Share Repurchase Program during the third quarter of 2015. As of September 30, 2015 , $271.3 remains available for repurchase under the 2015 Share Repurchase Program. The 2015 Share Repurchase Program has no expiration date. |

| Income Tax Disclosure [Abstract] | |
| Income Taxes | Income Taxes For the three and nine months ended September 30, 2015 , our effective income tax rates of 44.0% and 41.1% , respectively, were negatively impacted primarily by losses in certain foreign jurisdictions where we receive no tax benefit due to 100% valuation allowances and from the losses on sales of businesses for which we did not receive a full tax benefit. The negative impacts to our tax rates were partially offset by the reversal of a valuation allowance in Continental Europe. For the nine months ended September 30, 2015 , our effective income tax rate of 41.1% was also positively impacted by the recognition of previously unrecognized tax benefits as a result of the settlement of the 2010 U.S. federal income tax audit. We have various tax years under examination by tax authorities in various countries, and in various states, such as New York, in which we have significant business operations. It is not yet known whether these examinations will, in the aggregate, result in our paying additional taxes. We believe our tax reserves are adequate in relation to the potential for additional assessments in each of the jurisdictions in which we are subject to taxation. We regularly assess the likelihood of additional tax assessments in those jurisdictions and, if necessary, adjust our reserves as additional information or events require. With respect to all tax years open to examination by U.S. federal, various state and local, and non-U.S. tax authorities, we currently anticipate that total unrecognized tax benefits will decrease by an amount between $25.0 and $35.0 in the next twelve months, a portion of which will affect our effective income tax rate, primarily as a result of the settlement of tax examinations and the lapsing of statutes of limitations. We are effectively settled with respect to U.S. federal income tax audits for 2010 and years prior to 2009. With limited exceptions, we are no longer subject to state and local income tax audits for years prior to 2004 or non-U.S. income tax audits for years prior to 2006. |

| Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract] | |
| Employee Benefits Disclosure | Employee Benefits We have a defined benefit pension plan that covers certain U.S. employees (the “Domestic Pension Plan”). We also have numerous funded and unfunded plans outside the U.S. The Interpublic Limited Pension Plan in the U.K. is a defined benefit plan and is our most material foreign pension plan in terms of the benefit obligation and plan assets. Some of our domestic and foreign subsidiaries provide postretirement health benefits and life insurance to eligible employees and, in certain cases, their dependents. The domestic postretirement benefit plan is our most material postretirement benefit plan in terms of the benefit obligation. Certain immaterial foreign pension and postretirement benefit plans have been excluded from the tables below. The components of net periodic cost for the Domestic Pension Plan, the significant foreign pension plans and the domestic postretirement benefit plan are listed below.

IAN is comprised of McCann Worldgroup, Foote, Cone & Belding ("FCB"), Mullen Lowe Group, IPG Mediabrands, our digital specialist agencies and our domestic integrated agencies. CMG is comprised of a number of our specialist marketing services offerings. We also report results for the “Corporate and other” group. The profitability measure employed by our chief operating decision maker for allocating resources to operating divisions and assessing operating division performance is segment operating income (loss). Segment information is presented consistently with the basis described in our 2014 Annual Report on Form 10-K, except that segment operating income (loss) for the three and nine months ended September 30, 2015 and 2014 , respectively, includes a minimal impact of net restructuring and other reorganization-related reversals.

| Fair Value Disclosures [Abstract] | |
| Fair Value Measurements | Fair Value Measurements Authoritative guidance for fair value measurements establishes a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 Observable inputs other than Level 1 prices, such as 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 market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Financial Instruments that are Measured at Fair Value on a Recurring Basis We primarily apply the market approach to determine the fair value of financial instruments that are measured at fair value on a recurring basis. There were no changes to our valuation techniques used to determine the fair value of financial instruments during the nine months ended September 30, 2015 . The following tables present information about our financial instruments measured at fair value on a recurring basis as of September 30, 2015 , and December 31, 2014 , and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value. September 30, 2015 Balance Sheet Classification Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 133.2 $ 0.0 $ 0.0 $ 133.2 Cash and cash equivalents Short-term marketable securities 6.9 0.0 0.0 6.9 Marketable securities Long-term investments 0.5 0.0 0.0 0.5 Other non-current assets Total $ 140.6 $ 0.0 $ 0.0 $ 140.6 As a percentage of total assets 1.2 % 0.0 % 0.0 % 1.2 % Liabilities Mandatorily redeemable noncontrolling interests 1 $ 0.0 $ 0.0 $ 44.1 $ 44.1 December 31, 2014 Balance Sheet Classification Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 901.4 $ 0.0 $ 0.0 $ 901.4 Cash and cash equivalents Short-term marketable securities 6.6 0.0 0.0 6.6 Marketable securities Long-term investments 0.5 0.0 0.0 0.5 Other non-current assets Total $ 908.5 $ 0.0 $ 0.0 $ 908.5 As a percentage of total assets 7.1 % 0.0 % 0.0 % 7.1 % Liabilities Mandatorily redeemable noncontrolling interests 1 $ 0.0 $ 0.0 $ 32.8 $ 32.8 1 Relates to unconditional obligations to purchase additional noncontrolling equity shares of consolidated subsidiaries. Fair value measurement of the obligations was based upon the amounts payable as if the forward contracts were settled. The amounts redeemable within the next twelve months are classified in accrued liabilities; any interests redeemable thereafter are classified in other non-current liabilities. The following table presents additional information about financial instruments measured at fair value on a recurring basis and for which we utilized Level 3 inputs to determine fair value for the three and nine months ended September 30, 2015 and 2014 . Three months ended Nine months ended Liabilities 2015 2014 2015 2014 Mandatorily redeemable noncontrolling interests - Balance at beginning of period $ 44.9 $ 28.7 $ 32.8 $ 27.0 Level 3 additions 1.9 0.0 23.7 2.5 Level 3 reductions (3.9 ) 0.0 (15.3 ) (0.6 ) Realized losses/(gains) included in net income 1.4 0.1 2.3 (0.1 ) Foreign currency translation (0.2 ) 0.0 0.6 0.0 Mandatorily redeemable noncontrolling interests - Balance at end of period $ 44.1 $ 28.8 $ 44.1 $ 28.8 Realized losses/(gains) included in net income for mandatorily redeemable noncontrolling interests are reported as a component of interest expense in the unaudited Consolidated Statements of Operations. Financial Instruments that are not Measured at Fair Value on a Recurring Basis The following table presents information about our financial instruments that are not measured at fair value on a recurring basis as of September 30, 2015 , and December 31, 2014 , and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value. September 30, 2015 December 31, 2014 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Total long-term debt $ 0.0 $ 1,546.3 $ 77.5 $ 1,623.8 $ 0.0 $ 1,566.0 $ 80.4 $ 1,646.4 Our long-term debt is comprised of senior notes and other notes payable. The fair value of our senior notes traded over-the-counter is based on quoted prices for such securities, but for which fair value can also be derived from inputs that are readily observable. Therefore, these senior notes are classified as Level 2 within the fair value hierarchy. Our other notes payable are not actively traded, and their fair value is not solely derived from readily observable inputs. Thus, the fair value of our other notes payable is determined based on proprietary valuation methods and therefore are classified as Level 3 within the fair value hierarchy. See Note 2 for further information on our long-term debt. Non-financial Assets and Liabilities that are Measured at Fair Value on a Recurring Basis Certain non-financial assets and liabilities are measured at fair value on a recurring basis, primarily accrued restructuring charges. Non-financial Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis Certain non-financial assets and liabilities are measured at fair value on a nonrecurring basis, primarily goodwill, intangible assets, and property and equipment. Accordingly, these assets are not measured and adjusted to fair value on an ongoing basis but are subject to periodic evaluations for potential impairment. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies | Commitments and Contingencies Legal Matters We are involved in various legal proceedings and subject to investigations, inspections, audits, inquiries and similar actions by governmental authorities, arising in the normal course of business. The types of allegations that arise in connection with such legal proceedings may vary in nature but can include claims related to contract, employment, tax and intellectual property matters. We evaluate all cases each reporting period and record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount, or potential range, of loss can be reasonably estimated. In certain cases, we cannot reasonably estimate the potential loss because, for example, the litigation is in its early stages. While any outcome related to litigation or such governmental proceedings in which we are involved cannot be predicted with certainty, management believes that the outcome of these matters, individually and in the aggregate, will not have a material adverse effect on our financial condition, results of operations or cash flows. As previously disclosed, on April 10, 2015, a federal judge in Brazil authorized the search of the records of an agency's offices in São Paulo and Brasilia, in connection with an ongoing investigation by Brazilian authorities involving payments potentially connected to local government contracts. The Company had previously investigated the matter and taken a number of remedial and disciplinary actions. The company is in the process of concluding a settlement related to these matters with government agencies. Guarantees We have guaranteed certain obligations of our subsidiaries relating principally to operating leases and credit facilities of certain subsidiaries. The amount of parent company guarantees on lease obligations was $624.4 and $580.4 as of September 30, 2015 , and December 31, 2014 , respectively, and the amount of parent company guarantees primarily relating to credit facilities was $316.7 and $329.2 as of September 30, 2015 , and December 31, 2014 , respectively. In the event of nonpayment by the applicable subsidiary of the obligations covered by a guarantee, we would be obligated to pay the amounts covered by that guarantee. |

| New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
| Recent Accounting Standards | Recent Accounting Standards Business Combinations In September 2015, the Financial Accounting Standards Board (the “FASB”) issued amended guidance which requires measurement period adjustments to be recorded in the reporting period in which the adjustment amounts are determined. Previously, such adjustments were required to be retrospectively recorded in prior period financial information. This amended guidance will be effective for us beginning January 1, 2016, and applied prospectively, with early adoption permitted. We have early adopted this amended guidance as of the quarter ended September 30, 2015, and the adoption did not have a significant impact on our Consolidated Financial Statements. Revenue Recognition In May 2014, the FASB issued amended guidance on revenue recognition which requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB affirmed its proposal to delay the effective date of the new revenue standard by one year to January 1, 2018, with early adoption to be permitted as of the original effective date of January 1, 2017. We are currently assessing the impact the adoption of the amended guidance will have on our Consolidated Financial Statements. Debt Issuance Costs In April 2015, the FASB issued amended guidance which requires debt issuance costs to be presented as a direct deduction from the carrying value of the associated debt liability rather than as separate assets on the balance sheet. The FASB later issued guidance in August 2015 stating that debt issuance costs related to line-of-credit arrangements may be presented as an asset and subsequently amortized ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. This amended guidance will be effective for us beginning January 1, 2016. Early adoption is permitted, and the new guidance will be applied on a retrospective basis. We plan to early adopt this amended guidance as of the quarter ended December 31, 2015. We do not expect the adoption of this amended guidance to have a significant impact on our Consolidated Financial Statements. Consolidation In February 2015, the FASB issued amended guidance to the consolidation standard which updates the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amendment modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities and affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships, among other provisions. This amended guidance will be effective for us beginning January 1, 2016. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a significant impact on our Consolidated Financial Statements. Extraordinary and Unusual Items In January 2015, the FASB issued amended guidance which eliminates the concept of extraordinary items from generally accepted accounting principles. Prior to this amendment, an entity was required to separately classify and present an event or transaction that was determined to be both unusual in nature and infrequent in occurrence as an extraordinary item, net of tax, after income from continuing operations in the income statement. Upon adopting this amended guidance, a material event or transaction that an entity considers to be unusual or infrequent, or both, may still be presented separately but will now be presented on a pre-tax basis within income from continuing operations or disclosed in the notes to the financial statements. This amended guidance will be effective for us beginning January 1, 2016 and may be applied retrospectively or prospectively, with early adoption permitted. We have early adopted this amended guidance as of the quarter ended March 31, 2015, and the adoption did not have a significant impact on our Consolidated Financial Statements. Going Concern In August 2014, the FASB issued amended guidance which defines management's responsibility to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern and to provide related disclosures. Currently, this evaluation has only been an auditor requirement. Specifically, the amendments (1) provide a definition of the term “substantial doubt,” (2) require an evaluation every reporting period, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of the consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that financial statements are issued. This amended guidance will be effective for us beginning January 1, 2016. We do not expect the adoption of this amended guidance to have a significant impact on our Consolidated Financial Statements. Share-Based Payments with Performance Targets In June 2014, the FASB issued amended guidance which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This amended guidance will be effective for us beginning January 1, 2016 and can be either applied prospectively or retrospectively.

The aggregate lending limit of $1,000.0, or the equivalent in other currencies, and the ability to increase the commitments from time to time by an additional amount of up to $250.0 remain unchanged by the amendment. |
