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”), on July 19, 1999 (the “Liberty Schedule 13D”), is hereby amended and supplemented to include the information set forth herein.

Capitalized terms not defined herein have the meanings given to such terms in the Liberty Schedule 13D.

The information contained in Item 4 of the Liberty Schedule 13D is hereby amended and supplemented by adding the following information:

The information contained under Item 5 below is incorporated by reference in this Item 4.

Other than as provided herein, and except as contained in the agreements previously filed as exhibits to the Liberty Schedule 13D or as has been publicly announced by the Company or Liberty, Liberty does not have and, to the best of Liberty’s knowledge, none of its directors or officers have, any plans or proposals that relate to or would result in any of the actions set forth in clauses (a) through (j) of Item 4.

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 January 15, 2009 through February 20, 2009, Liberty sold in open market transactions through a broker an aggregate of 2,109,800 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

01/15/2009	119,600	$	15.10
01/16/2009	262,300	$	15.18
01/20/2009	56,900	$	15.03
01/22/2009	63,700	$	15.03
01/23/2009	173,700	$	15.02
01/26/2009	42,300	$	15.03
01/27/2009	143,000	$	15.02

Date of Sale	Number of shares of Common Stock Sold	Per Share Weighted Average Sale Price

01/28/2009	176,000	$	15.08
01/29/2009	93,000	$	15.04
01/30/2009	19,400	$	15.08

02/12/2009	151,500	$	15.06
02/13/2009	207,700	$	15.07
02/20/2009	377,800	$	15.08

In addition, on January 21, 2009, February 2, 2009 and February 17, 2009, Liberty sold 6,000, 200 and 8,600 shares of Common Stock, respectively, in open market transactions through a broker for $15.00 per share.

Liberty beneficially owns (i) 28,527,502 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 22.4% 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 29.4% 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 61.2% 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 127,597,911 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, 2008.
