The New York Yankees are noted for having won more titles than any other US major professional sports franchise. The Yankees' chief rivals, the Boston Red Sox, also enjoy a huge following in Boston and throughout New England. The Philadelphia Phillies of the National League are the oldest continuous, one-name, one-city franchise in all of professional American sports, and enjoy a fanbase renowned for their rabid support of their team throughout Philadelphia and the Delaware Valley, and have famously been dubbed as the "Meanest Fans in America". Midwest baseball has also grown exponentially with teams like the Chicago Cubs, St. Louis Cardinals, and Cincinnati Reds. Particularly with Chicago sports fans who avidly follow the Chicago Cubs and the Chicago White Sox despite the comparative lack of success for the teams, with Chicago Cub fans being known throughout the country as one of the best baseball fans in the country, most notably for their passionate loyalty to the team despite their not having won a championship from 1908 to 2016 (108 years) which stands as the longest championship drought in US sports history. The sport has also taken hold of fans on the West Coast, most notably the rivalry between the San Francisco Giants and The Los Angeles Dodgers. Historically, the leagues were much more competitive, and cities such as Boston, Philadelphia and St. Louis had rival teams in both leagues up until the 1950s.
