The top three in terms of most championships would be the Packers, Bears and Giants.  The NFL was founded in 1920 and the 49ers were only really successful from 1981 to 1994.

teams are the ones that have a national fan base more than any other franchise. I see NFL apparel featuring these team's logos across the United States.

Now if you meant influential or winningest teams, that is different agrument. You see Liorr, that is the trouble with your posts, nobody knows what you mean. Practice precision in expression and you will find people will respond to you better.
