Three different folks have written to tip me off to the name of the person who, they say, has been quietly signed to host The Late, Late Show (i.e., the 12:35 show that follows Letterman). All three asked me not to mention the name here, so I won't. But I don't think it would be violating their request if I say that the identity of the alleged new host appears in this New York Times article by Bill Carter.
Carter mentions that Stephen Colbert of The Daily Show turned down the job. Colbert is easily one of the three funniest people seen regularly on my TV these days, but I think he's better suited to what he's already doing. (I think he also has a pilot for another show lurking at one of the networks…)
