Nearly 30 years after the Tanner family first appeared on television in Full House in 1987, its sequel hit Netflix, showing how much the Fuller House cast and characters had grown up from the original. When it first premiered, Full House was a hit for ABC, introducing one of the most beloved families in sitcom history and launching cast members into stardom. The original series followed a newly-widowed father of three young girls and his attempts to raise them alongside his brother-in-law and their best friend. Fuller House kept the same premise, this time centering around DJ, the oldest of the three Tanner daughters, and her three sons.
