Best: Johnny Carson
Considering Carson’s iconic status, it’s easy to forget he wasn’t the original host of “The Tonight Show.” He was handed the keys by Jack Paar, who was preceded by Steve Allen. Carson would rule late-night television from 1962-1992, when he passed the wand to Jay Leno after 4,531 shows. —XFINITY Entertainment Staff (Photo: Douglas C. Pizac, AP Images)
