SCHEDULE 13D/A

Statement of

LIBERTY MEDIA CORPORATION

Pursuant to Section 13(d) of the Securities Exchange Act of 1934 in respect of

IAC/INTERACTIVECORP

This Report on Schedule 13D relates to the common stock, par value $.001 per share (the “Common Stock”), of IAC/InterActiveCorp, a Delaware corporation (“IAC” or the “Company”). The Report on Schedule 13D, as amended and supplemented, originally filed with the Commission by Liberty Media Corporation, a Delaware corporation (“Liberty” or the “Reporting Person”), on July 19, 1999 (the “Liberty Schedule 13D”), is hereby amended and supplemented to include the information set forth herein. This amended statement on Schedule 13D/A (this “Amendment”) constitutes Amendment No. 27 to the Liberty Schedule 13D. Capitalized terms not defined herein have the meanings given to such terms in the Liberty Schedule 13D.

ITEM 5. Interest in Securities of the Issuer

The information contained in Item 5 of the Liberty Schedule 13D is hereby amended and supplemented by adding the following information:

From November 25, 2009 through December 11, 2009, Liberty sold in open market transactions through a broker an aggregate of 2,000,000 shares of Common Stock. The table below sets forth for each day that Liberty sold shares of Common Stock the number of shares sold on such day and the per share weighted average sale price for such sales:

Date of Sale	Number of shares of Common Stock Sold	Per Share Weighted Average Sale Price
11/25/2009	210,500	$	19.81
11/27/2009	115,100	$	19.42
11/30/2009	196,200	$	19.39
12/01/2009	243,500	$	19.47
12/02/2009	168,100	$	19.29
12/03/2009	130,900	$	19.13
12/04/2009	306,400	$	19.14
12/07/2009	234,200	$	19.03
12/08/2009	210,700	$	19.13
12/09/2009	88,100	$	19.03
12/10/2009	78,900	$	19.10
12/11/2009	17,400	$	19.00

Liberty beneficially owns (i) 15,492,402 shares of Common Stock, of which amount, based on publicly available information, 4,289,499 shares are held by Mr. Diller, and (ii) 12,799,999 shares of Class B Common Stock. Such shares constitute 13.0% of the outstanding shares of Common Stock and 100% of the outstanding shares of Class B Common Stock, respectively. Pursuant to the Governance and Stockholder Agreements, subject to certain limitations, Mr. Diller holds an irrevocable proxy with respect to all securities of the Company beneficially owned by Liberty on all matters submitted to a stockholder vote or by which the

stockholders may act by written consent, except for Contingent Matters with respect to which Liberty has not consented. In addition, Liberty may be deemed to have shared voting power over the shares of Common Stock held by Mr. Diller because, under the terms of the Governance and Stockholder Agreements, Mr. Diller must vote those shares in favor of Liberty’s designees for the Company’s board of directors and against any Contingent Matter that Liberty has not approved. Assuming the conversion of all of the shares of Class B Common Stock beneficially owned by Liberty into Common Stock, Liberty would beneficially own 21.4% of the outstanding Common Stock (calculated in accordance with Rule 13d-3). Because each share of Class B Common Stock generally is entitled to ten votes per share and each share of Common Stock is entitled to one vote per share, Liberty may be deemed to beneficially own equity securities of the Company representing approximately 58.1% of the voting power of the Company. The foregoing beneficial ownership amounts exclude shares of Common Stock beneficially owned by the executive officers and directors of Liberty. The foregoing beneficial ownership amounts are based on 119,170,241 shares of Common Stock and 12,799,999 shares of Class B Common Stock outstanding, in each case, based on amounts disclosed in the Company’s Quarterly Report on Form 10-Q for the quarter ending September 30, 2009. As more fully described in Amendment No. 21 to the Liberty Schedule 13D, 7,500,000 shares of Common Stock beneficially owned by the Reporting Person are subject to a forward sale transaction.
