There's no denying online video is ripe for monetization through more pervasive in-stream advertising, and today's public beta launch of same across the ValueClick Media network is yet another signal.

Following the footsteps of ad network competitors like Advertising.com and 24/7 Real Media, the firm is now allowing its publishers to provide pre- and post-roll video, display and rich media ads to advertisers, reports ClickZ News. ValueClick will also target video spots based on previous user behavior.

A quarter of the 13,500 publishers in the network have video content on their sites, said ValueClick Media GM David Yovanno. The company expects that number to double in Q1 of next year, he added. About 150 publishers are set to serve up video ads from more than 100 advertisers through the system, Yovanno told ClickZ.

The platform enables pre- and post-roll video in addition to static graphical images served directly within the video player before and after content plays. Advertiser verticals the network typically sells to, including telecom, pharmaceutical, consumer electronics and automotive have all experimented through the video network, he continued.
