A game-changer, Tina Fey started as SNL’s first female head writer before even joining the cast. She transformed the show’s tone with her sharp, witty, and culturally aware writing. She then moved in front of the camera, co-anchoring ‘Weekend Update’ with Jimmy Fallon and later Amy Poehler, where her nerdy sex appeal resonated. Her impression of Sarah Palin in 2008 as a guest performer wasn’t just comedy; it was a major cultural event. After SNL, she created, wrote, and starred in the hit sitcom 30 Rock. Fey is one of the most influential people to ever contribute to the show.
