All through "CSI: Miami"'s last three seasons as well as the current season, GM's hummer has been a prominent online and television sponsor, and has featured throughout as the "official crime scene vehicle."
Other bonus material produced by CBS.com includes footage from recent behind-the-scenes footage, and interviews with cast and crew members.
Nearly all of CBS's advertisers are looking into online options, according to Linda René, CBS's senior vice president of prime-time sales. "This is a relatively customized deal with Hummer, but we have online extensions for many of our television partners," said René.
CBS has recently been conducting similar tests with its prime-time content online. In early November, CBS agreed to make three entire episodes of its sci-fi series "Threshold" available at CBS.com for three days each.
