Norman Lear changed the television landscape forever with the creation of shows like "All in the Family" and "The Facts of Life."

Lear died of natural causes at his home Tuesday in Los Angeles surrounded by his family at the age of 101.

While Lear's sitcoms were a ratings success, they also touched on social topics — racism, homosexuality and war. "All in the Family" was Lear's first, of many, successful sitcoms, earning him four Emmys throughout its run in the '70s.
