As audiences flock to theaters for ensemble comedies (The Hangover, Bridesmaids, Horrible Bosses, and Tower Heist) and buddy comedies (The Other Guys, The Change-Up, 30 Minutes or Less, and Harold & Kumar), less and less comedies are featuring one lead actor.
So it would appear that the era of the comedic leading actor has ended. Triple threats, who write, direct, and produce their own content, are the future. And sharing the spotlight is the key to making sure they have one. The question is whether audiences who prefer duos and ensembles to solitary lead roles are simply interested in getting more laughs for their buck, or if actors who are flying solo (and the screenwriters who feed them their lines) just aren't worth it anymore.
