Organization, Basis Of Presentation And Recent Accounting Pronouncements [Abstract]
Financial Periods	Financial Periods – In the fourth quarter of 2011, the Company changed its fiscal quarter from a thirteen week quarter ending on the Sunday nearest the calendar quarter-end to a quarterly month end. The fiscal quarters for 2012 and 2011 ended on September 30, 2012, June 30, 2012, March 31, 2012, October 2, 2011, July 3, 2011, and April 3, 2011, respectively. Subsidiaries of the Company report on a calendar-quarter basis, with the exception of most of the newspaper publishing operations, which report on a thirteen week quarter ending on the Sunday nearest the calendar quarter-end.
Basis of Presentation	Basis of Presentation – The accompanying condensed consolidated financial statements have been prepared in accordance with: (i) generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information; (ii) the instructions to Form 10-Q; and (iii) the guidance of Rule 10-01 of Regulation S-X under the Securities and Exchange Act of 1934, as amended, for financial statements required to be filed with the Securities and Exchange Commission (SEC). They include the assets, liabilities, results of operations and cash flows of the Company, including its domestic and foreign subsidiaries that are more than 50% owned or otherwise controlled by the Company. As permitted under such rules, certain notes and other financial information normally required by GAAP have been condensed or omitted. Management believes the accompanying condensed consolidated financial statements reflect all normal and recurring adjustments necessary for a fair presentation of the Company's financial position, results of operations, and cash flows as of and for the periods presented herein. The Company's results of operations for the quarterly periods ended September 30, 2012 and October 2, 2011 may not be indicative of the Company's future results. These condensed consolidated financial statements are unaudited and should be read in conjunction with the Company's audited consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2011. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. Certain amounts in previously issued financial statements have been reclassified to conform to the current year presentation, which includes the reclassification of the results of operations of certain Kaplan and Other businesses as discontinued operations for all periods presented.
Use of Estimates in the Preparation of the Condensed Financial Statements	Use of Estimates in the Preparation of the Condensed Consolidated Financial Statements – The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported herein. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates.
Discontinued Operations	Discontinued Operations – A business is classified as a discontinued operation when (i) the operations and cash flows of the business can be clearly distinguished and have been or will be eliminated from the Company's ongoing operations; (ii) the business has either been disposed of or is classified as held for sale; and (iii) the Company will not have any significant continuing involvement in the operations of the business after the disposal transactions. The results of discontinued operations (as well as the gain or loss on the disposal) are aggregated and separately presented in the Company's condensed consolidated statement of operations, net of income taxes. The assets and related liabilities are aggregated and separately presented in the Company's condensed consolidated balance sheet.

Disclosure of accounting policy for subsidiaries or other investments that are consolidated, including the accounting treatment for intercompany accounts or transactions and any noncontrolling interest.

The results of operations of a component of an entity that either has been disposed of or is classified as held for sale is reported in discontinued operations if both: (a) the operations and cash flows of the component have been (or will be) eliminated from the ongoing operations of the entity as a result of the disposal transaction and (b) the entity will not have any significant continuing involvement in the operations of the component after the disposal transaction. If the entity elects to allocate interest expense to a discontinued operation, it may disclose its accounting policy for this election and describe its method of allocation.
