Ad serving company ZEDO, Inc. announced the launch of an Intromercial ad format for their publisher clients.

Intromercial is a full-page ad that plays for ten seconds before the users sees the front page of a site. After the ad plays, it resolves to a small corner banner on the next page.

"With increasing popularity of rich media, there is a significant demand from customers to implement new and innovative ad formats," says Roy de Souza, chief executive officer, ZEDO.

ZEDO says that a survey of some clients showed a 38 percent higher click-through for Intromercial ads as opposed to normal banner ads. ZEDO's clients include CNET Networks and Glispa and NextGame.

"The ZEDO Intromercial ad format is a simple, repeatable format that sets a good standard for advertisers. It's a format advertisers like, understand and they are willing to pay well for," adds de Souza.
