league clubs. MLB and the World Baseball Softball Confederation jointly manage the international World Baseball Classic tournament. MLB is the second-wealthiest professional sport league by revenue after the National Football League (NFL). Since the first World Series in 1903, the New York Yankees have the most championships with 27. The Houston Astros are the reigning World Series champions, as they defeated the Philadelphia Phillies 4–2 in the 2022 World Series, to mark the end of the 2022 season. Organizational structure MLB is governed by the Major League Baseball Constitution. This document has undergone several incarnations since its creation in 1876. Under the direction of the Commissioner of Baseball, MLB hires and maintains the sport's umpiring crews, and negotiates marketing, labor, and television contracts. MLB maintains a unique, controlling relationship over the sport, including most aspects of Minor League Baseball. This is due in large part to the 1922 U.S. Supreme Court ruling in Federal Baseball Club v. National League, which held that baseball is not interstate commerce and therefore not subject to federal antitrust law; MLB is the only league that has such a status, and has not faced any competition since this case. This ruling has been weakened only slightly in subsequent years. The weakened ruling granted more stability to the owners of teams and has resulted in values increasing at double-digit rates. There were several challenges to MLB's primacy in the sport, with notable attempts to establish competing leagues occurring during the late 1800s, from 1913 to 1915 with the short-lived Federal League, and in 1960 with the aborted Continental League. The chief executive of MLB is the commissioner, currently Rob Manfred. The deputy commissioner of baseball administration and chief legal officer is currently Dan Halem. There are seven other executives: executive vice president and general counsel, chief operations and strategy officer, chief communications officer, chief financial officer and senior advisor, executive vice president and chief marketing officer, chief revenue officer, and chief baseball development officer. The multimedia branch of MLB is MLB Advanced Media, which is based in New York City. This branch oversees MLB.com and each of the 30 teams' websites. Its charter states that MLB Advanced Media holds editorial independence from the league, but it is under the same ownership group and revenue-sharing plan. MLB Productions is a similarly structured wing of the league, focusing on video and traditional broadcast media. MLB also owns 67
