AtomShockwave has launched the Shockwave.com Immersive Network, which allows advertisers to dynamically insert ads within the company's popular games, writes AdAge (via MediaBuyerPlanner). A brand's logo will be able to appear on billboards, vehicles and elsewhere within the gameplay. Up to five companies may be featured during a single game, but an advertiser can also buy up all the impressions within a game for a specific period of time.

Last month, Shockwave.com had 22 million unique visitors who played more than 25 million game sessions.

The Immersive Network is an answer to the increasing numbers of companies who wanted Shockwave to create brand-backed games - as it has done for companies such as Radio Shack, McDonald's and Honda - in hopes of attracting the company's lucrative young audience.

The Shockwave Immersive Network will be able to deliver 10-12 million impressions per month. It hopes to increase that to 50 million by early 2006. Ad impressions will run from three to seven seconds on average, though they could be much longer in some games.
