Craig Kilborn bailed from his CBS late night show some years ago (replaced successfully by Craig Ferguson) and he's been virtually invisible since then. A couple years back, IIRC, Kilborn did a couple of weeks of pilot shows along the lines of what he'd been doing on CBS, and they aired on MyNetwork affiliates in New York, LA and a few other big markets. If it got good sampling and good reviews, the show was going to be plugged into the MyNetwork national schedule either in prime time or late night.
Evidently the numbers weren/t good because after the trial run ended, nothing more was heard of it or of Kilborn.
