What is America's number one sport ?

baseball or football imo

football followed by MMA.

certainly not basketball

i would say baseball and football, with college football being at least as popular as NFL, and college basketball being more popular than NBA. ice hockey is not even close.

baseball

Football and based on tv ratings the next best is Nascar.

baseball

college football is the most supported

Football by miles, if you've ever been to America during the Football season you will know that it absolutely dominates TV coverage ahead of MLB/NBA etc. The only way you could have Baseball on top is by "total attendance" which is because they play 162 games each.

Baseball is slightly ahead of Basketball judging by the viewing figures for the World Series/NBA Finals. Ice Hockey is way behind and only a matter of time before Soccer overtakes it.

Lacrosse fastest growing.

Not bad for the oldest sport then.

baseball is huge judging by wagessome of the players are on, money always talks loudest of course

Baseball??, comes nowhere near football.

top paid sportsman is a baseball player so must be quite big imo!!

nfl for 5 months of the year, mlb for the other 7

Baseball

NFL (by miles)
College Football
Baseball (players salaries have nothing to do with it, they just play more games)
NBA and College Basketball tied
NHL (way behind in US but clear Number one in Canada)

football.

invasions

Football

MASSIVE GAP

Baseball
Basketball

MASSIVE GAP (although in the mid 90s very small gap)

Ice Hockey

and lol whoever says baseball.

BCDoug

taking coast to coast into consideration, wouldn't you have College rated over NFL?

Or atleast the gap is almost negligible.
