I think the Steelers have!
The first NFL Super Bowl was in 1967, so there was no Super Bowl in 1952.
The Cowboys of course.
The alternate name for the first Super Bowl was The First World Championship Game, AFL vs NFL.
The Green Bay Packers won what were retrospectively named Super Bowl I and II, but then they were named the NFL-AFL championship game. The NY Jets were the first team to win a Super Bowl when it was called the Super Bowl.
thePittsburgh Steelers have had 14 super bowl appearances in the last 20 years
The Bears won 6 NFL Championships prior to the first Super Bowl.
