IAC's new Manhattan HQ

InterActiveCorp. Chairman and CEO Barry Diller said the company will unveil a new local information service Dec. 4 that combines the functions of Ask.com, CitySearch, Evite, and Ticketmaster.

"We are coming out with AskCity, which is our local service," Diller told the Reuters Media Summit in New York. "It integrates maps, integrates events, integrates all of these different attributes that we have got in the best thing you will be able to use in a city to do things."

Ask.com is looking to stay several steps ahead of far larger search rivals Google, Yahoo and Microsoft by innovating faster and taking advantage of its stable of web and e-commerce sites, he said.

IAC has focused on growing its existing businesses, in sharp contrast to years of relying on a regular stream of fresh acquisitions to drive growth across the network of companies.
