Wednesday is the 25th anniversary of the first half-hour episode of "The Simpsons," entitled "Simpsons Roasting on an Open Fire."


By contrast, Thursday sees the final episode of "The Colbert Report" on Comedy Central, as host Stephen Colbert moves on to succeed David Letterman as host of "The Late Show" here on CBS next spring.
