However, the Harris Poll only allows one unaided selection of a "favorite sport." Other studies and polls such as the ESPN Sports Poll and the studies released by the Associated Press and conducted by Sports Marketing Group from 1988 to 2004, show far higher levels of popularity for NFL Football since they list from thirty to over 100 sports that each respondent must rate. According to the Associated Press, the Sports Marketing Group polls from 1988 to 2004 show NFL Football to be the most popular spectator sport in America. The AP stated that "In the most detailed survey ever of America's sports tastes" researching "114 spectator sports they might attend, follow on television or radio or read about in newspapers or magazines, the NFL topped all sports with 39 percent of Americans saying they loved it or considered it one of their favorites." The total percentage of Americans who liked or loved NFL Football exceeds 60% of the American Public.
The NFL has the highest per-game attendance of any domestic professional sports league in the world, drawing over 67,000 spectators per game for each of its two most recently completed seasons, 2006and 2007. However, the NFL's overall attendance is only approximately 20% of Major League Baseball, due to the latter's longer schedule (162-game scheduled regular season).
