their upstart rivals to fold outright by adding more teams. However, the upstart leagues owed their success in large part to the reluctance of owners in the established leagues to devote the majority of their revenues to player salaries and also to sports leagues' former reliance primarily on gate receipts for revenue. Under those conditions, an ambitious rival could often afford to lure away the sport's top players with promises of better pay, in hopes of giving the new league immediate respect and credibility from fans. Today, however, established leagues derive a large portion of their revenue from lucrative television contracts that would not be offered to an untested rival. Also, the activism of players' unions has resulted in the established leagues paying a majority of their revenues to players, thus the average salary in each of the big four leagues is now well in excess of $1 million per season. Under present market and financial conditions, any serious attempt to form a rival league in the early 21st century would likely require hundreds of millions (if not billions) of dollars in investment and initial losses, and even if such resources were made available the upstart league's success would be far from guaranteed, as evidenced by the failure of the WWF/NBC-backed XFL in 2001 and the UFL from 2009 to 2012. The current major leagues have established lucrative relationships with all of the major media outlets in the United States, who subsidize the league's operations because their established fame ensures strong ratings; the networks are far less willing to provide such coverage to an unproven upstart league, often requiring the upstart league to pay the network for those leagues to be covered. Therefore, as long as leagues choose not to expand and/or reject a city's application, the only realistic recourse is to convince the owner(s) of an existing team to move it (or convince a prospective owner to purchase a team with the intent of moving it). Owners usually move teams because of weak fan support or because the team organization is in debt and needs an adequate population for financial support or because another city offers a bigger local market or a more financially lucrative stadium/arena deal. Governments may offer lucrative deals to team owners to attract or retain a team. For example, to attract the NFL's Cleveland Browns in 1995, the state of Maryland agreed to build a
