CBS is in negotiations to commit to multiple seasons of the highest-rated comedy on television, Two and a Half Men, and this season's half-hour ratings surprise The Big Bang Theory, according to The Hollywood Reporter.

Two and a Half Men is being eyed for three seasons.

The Big Bang Theory is near a deal for two seasons -- a terrific show of faith to a comedy considered a slow starter just last year.
