Pronto.com™, an operating business of IAC (NASDAQ: IACI), today announced that it has been named as a "Top Ten Gaining Property" by comScore, Inc. in December 2007 with 37% month-over-month growth. Additionally, Pronto.com was ranked #7 in Compete.com, Inc.'s list of "2007's Fastest Moving Sites", with a growth rate surpassing 2800% in one year and ending December 2007 with 9.7 million monthly unique visitors.

Pronto.com's explosive traffic growth through the second half of 2007 coincides with its entree into the Social Shopping space. In August 2007, Pronto.com expanded its service from simply a comparison shopping engine to an online shopping community. With the addition of social media tools giving users the ability to build personal profiles, add friends and family, and take advantage of community driven product recommendations, Pronto.com offers shoppers a fun and engaging experience to help them decide not only what to buy, but where to buy it.

Internal metrics show that these socially-driven shoppers are almost 3 times as engaged as typical online shoppers, helping to fuel Pronto.com's rapid growth. By viewing more pages, conducting more searches, and writing more reviews than traditional internet users, social shoppers offer advertisers a unique opportunity to target the most influential online shoppers. By capturing this group of engaged consumers, Pronto.com anticipates that it will continue its growth trajectory and drive hundreds of millions of dollars in online purchases in 2008.

"Our significantly increased reach and engagement metrics mesh well for our new display media opportunities and our core retail product listings," said Greg Stevens, Chief Revenue Officer at Pronto.com. "We're finding that our new social shopping features attract users who are earlier in the buying process and as such, are more easily influenced by targeted media campaigns. We are narrowing the gap between advertisers and their core targets by creating opportunities for advertisers to spark a dialogue with active shoppers at the critical moment when they are making purchase decisions."

Pronto.com's new display advertising offering enables online merchants and brand advertisers the ability to target shoppers in a variety of unique ways:

• Category targeting that allows advertisers to reach shoppers on a granular level in over 300 retail product segments
• Custom integrations that include targeted newsletters, as well as participation in sweepstakes, and promotions
• Integrated product listings that enable Pronto.com users to add advertisers' products to their Wish Lists to share with friends and family
• Thematic sponsorship packages around holidays and major gifting events
