Mandatorily Redeemable Financial Instrument [Abstract]
Mandatorily Redeemable Financial Instrument [Text Block]	Mandatorily Redeemable Financial Instrument On November 9, 2012, the Company acquired substantially all of the issued and outstanding capital stock of Ziff Davis, Inc. ("Ziff Davis"). In connection with the acquisition, the issued and outstanding capital stock was exchanged for shares of Series A Cumulative Participating Preferred Stock ("Series A Stock") of Ziff Davis. Ziff Davis is accounted for as a consolidated subsidiary as of the date of acquisition. Certain minority interest holders received an ownership in Series A Stock which has been accounted for as a non-controlling interest. On December 31, 2013, in connection with a reorganization of Ziff Davis, Inc. to Ziff Davis, LLC (the "Reorganization"), the Company acquired all of the minority interest holders' equity interests, including their Series A Stock. The Series A Stock bore a 15% annual cumulative dividend, compounded quarterly, whether or not earned or declared and whether or not there are funds legally available for payment of dividends. The Series A Stock was subject to mandatory repayment or redemption on November 9, 2017, which Ziff Davis could repay or redeem the Series A at its option prior to the mandatory repayment or redemption date. The repayment amount represented $1,000 for each share of Series A Stock and all accrued but unpaid dividends, subject to certain reduction when repaid. The redemption amount represented $1,000 for each share of Series A Stock and all accrued but unpaid dividends plus the fair market value of a notional number of shares of Ziff Davis common stock on a basis of 485 5/7 common shares per share of Series A Stock. The Series A Stock met the definition of a mandatorily redeemable financial instrument which requires liability classification and remeasurement at each reporting period on the consolidated subsidiaries financial statements. As the fair value of the Series A Stock was less than the mandatory redemption amount at issuance, periodic accretions using the interest method were made so that the carrying amount equaled the redemption amount on the mandatory redemption date. In connection with Reorganization, the Company issued to the minority holders shares of j2 common stock, j2 Series A Preferred Stock and j2 Series B Preferred Stock equal to the fair market value of the minority holders' Series A Stock (see Note 12 - Stockholders' Equity). As a result of the Reorganization, the Series A Stock was extinguished, resulting in loss on extinguishment of debt and related interest expense of $14.4 million within the consolidated statement of income, in accordance with ASC 480, Distinguishing Liabilities from Equity.
