Cable network TBS has announced plans to extend the run of their late night offering, Conan (with Conan O’Brien) for another two seasons. This news isn’t unsurprising, what with ratings for Conan slumping heavily following a good lead in November 2010 when O’Brien made the move from NBC. It seems the network is more heavily investing in probable progress rather than exact performance, as evidenced by George Lopez getting the ax after a similarly disappointing run. The ratings have been rising though, if not slowly, but rising just the same. Some are attributing the increase to Conan now following reruns of The Big Bang Theory, others to Conan’s obvious popularity, but either way, Conan will need more than a slight increase in viewership to get yet another extension in two years time.
