Seinfeld (1989-1998) starred Jerry Seinfeld, a stand-up comic who played himself.
The other actors on the show played, well, somewhat unusual characters: Kramer, George, and Elaine.
The show concentrated its plots around small, everyday things, like taking clothes to the drycleaners, getting tickets for an important game, arguing over parking spaces, and using answering machines.
These were trivial things, but ones with which the audienee could identify. As Jerry Seinfeld said about his program, it was “a show about nothing.”
