With the exception of Baltimore, all of the American teams consistently lost money. CFL games in the United States averaged 10,000 to 15,000 in paid attendance, while the Stallions ranged from 30,000 to 37,000. (The CFL was, and remains to the present day, a gate-driven league dependent on ticket sales and game-day revenue for most of its income.) Tension also arose between the American and Canadian contingents over rule changes, scheduling, import rules, and even the name of the league itself. Facing these difficulties, the league returned to being an exclusively Canadian one beginning with the 1996 season.
