new stadium in Baltimore and allow the team to use it rent-free and keep all parking, advertising and concession revenue. (This move proved so unpopular in Cleveland that the move was treated as the Baltimore Ravens being awarded an expansion franchise, and the Browns name and their official lineage would remain in Cleveland for a "reactivated" team that rejoined the NFL three years later.) A little more than a decade earlier, the Baltimore Colts left for Indianapolis (NFL owners voted to give Colts owner Robert Irsay permission to move his franchise to the city of his choosing after no satisfactory stadium would be built). Moving sports teams is often controversial. Opponents criticize owners for leaving behind faithful fans and governments for spending millions of dollars of tax money on attracting teams. However, since sports teams in the United States are generally treated like any other business under antitrust law, there is little sports leagues can do to prevent teams from flocking to the highest bidders (for instance, the Los Angeles Rams filed suit when the other NFL owners initially blocked their move to St. Louis, which caused the NFL to back down and allow the move to proceed). Major League Baseball, unique among the major professional sports leagues, has an exemption from antitrust laws won by a Supreme Court decision but nonetheless has allowed several teams to change cities. Also recently, courts denied the attempted move of the team then known as the Phoenix Coyotes by siding with the NHL, which claimed that it had final authority over franchise moves. Newer sports leagues tend to have more transient franchises than more established, "major" leagues, but in the mid-1990s, several NFL and NHL teams moved to other cities, and the threat of a move pushed cities with major-league teams in any sport to build new stadiums and arenas using taxpayer money. The trend continued in the 2000s, when three National Basketball Association (NBA) teams moved in a seven-year span after there were no moves at all in the 16 years before it. Critics referred to the movement of teams to the highest-bidding city as "franchise free agency."

Both competitions were originally based in one city (Melbourne and Sydney respectively) and expanded to a national level, and through that
