IAC/InterActiveCorp (also known as IAC) is an American internet company with over 50 brands across 40 countries headquartered in New York City. The Chairman and Senior Executive is Barry Diller, who was previously head of Paramount Pictures, Fox Broadcasting, and USA Broadcasting.
IAC was incorporated in 1986 under the name Silver King Broadcasting Company, as a subsidiary of the Home Shopping Network. In 1992, Silver King was spun-off to Home Shopping Network shareholders as a separately traded public company.
The company was originally named HSN, Inc. Its name was changed to USA Networks, Inc. in February 1998; to USA Interactive in May 2002; to InterActiveCorp in June 2003; and finally to IAC/InterActiveCorp in July 2004.

In April 2011, IAC extended the deal with Google to hand over all search advertising on Ask.com and other IAC search products to the search giant, which was worth $3.5 billion in 2007, to end on March 31, 2016.
On February 14, 2012, Barry Diller introduced Aereo, an Internet television service. In March 2012 in New York City, Aereo will stream all of the broadcast networks to smartphones, tablets and televisions with Internet capability.
