The channels joining The Web TV's ad network will feature video content from Future's games websites gamesradar.com and computerandvideogames.com, plus news on T3.com and cycling product reviews from bikeradar.com.
The launches are part of Future's objective to roll out video channels across each of its specialist sectors.
The Web TV Enterprise, founded in 2006, provides advertisers with 45 channels on which to place pre- and post-roll ads.
Simon Stone, commercial director of the company, said the deal with Future presented a "unique opportunity" for advertisers to engage an 18 to 34 male audience online.
"Pre-roll advertising in the UK is really taking off right now and with exciting new web TV channels launching, we expect to see this market continue to grow at a rapid pace," he said.
