1946, began the establishment of the league organizational structure from a non-profit corporation to a "for profit" franchises system. The goal that Wrigley had for the League was re-directed towards being a profitable business. Teams often had Junior leagues for developmental purposes to insure quality players would be available to the AGBBL to allow the League to develop more players, add teams and make more profits for the stockholders.
Chicago was the beginning of the franchise era. The city already had a Junior League supported by the AAGPBL which had started two years earlier with cooperation from the Chicago Parks and Recreational baseball programs for girls. Now, it was agreed upon by Meyerhoff and the newly created Board of Directors to bring a franchise to Chicago. This had been the primary goal when Wrigley decided to create the League though he was not in favor of the organization becoming a "for profit" League.
The League was at the pinnacle of its success as an established professional baseball league in 1947. Under the management administrative guidelines implemented the beginning of the 1946 season teams in the League were solvent and the stockholders were making profits.
The next two years changed the path that the League had expected to travel. At the end of the 1947 season the Coleens were not showing a profit and were losing fans. The economy had recuperated from the burdens of WWII and life in America had become better for everyone, but the advent of television was now bringing baseball to the fan and many fans no longer went to city parks to watch games. By the middle of the 1948 season the Chicago Coleens had lost their franchise and would become a touring team.
