Broadband TV network Heavy.com this week announced a slate of seven on-demand three-minute, three-episode comedy series, including "Gangster Nanny 911," "Tourettes Cowboy" and "Honey, I Killed the Geezer," reports MediaPost. The web-based episodes - Heavy.com calls them "machinama" - are made using recorded gameplay from video games, dubbed with new audio. "Gangster Nanny 911," for example, uses gameplay from Activision's "True Crime 2." The videogame producers have purchased ad space on Heavy.com. There are display ads around the content, but no interstitial ads in the video streams.
