Despite Conan O'Brien's plummeting ratings, TBS plans to invest heavily in new programming to air before and after his 11 00 p.m. show, the Wall Street Journal reported today (Thursday). The newspaper reported today (Thursday) that O'Brien's ratings have tumbled about 60 percent since his premiere last September (to 958,000 viewers from 2.4 million) and that overall viewership for the channel among 18-49-year-olds has dropped 11 percent versus last season. In an interview with the newspaper, Turner Entertainment Networks President Steve Koonin said, "We want TBS to be a leading comedy brand." However, he conceded, "How we get to that destination we don't have 100 percent mapped out today." But Koonin offered unsparing support for O'Brien. "Conan personifies the smart funny tone that we want TBS to have," he said. "His program is the signature show of our line-up and the centerpiece of our network."
