The folks who gave us the “Chicago: Second to None” campaign are about to become the only game in town for Chicago tourism efforts.

Mayor Rahm Emanuel announced today that the city’s tourism functions handled by the Chicago Office of Tourism and Culture, will be shifted to the private, nonprofit (but mostly tax-funded) Chicago Convention and Tourism Bureau, beginning immediately, with the change complete by this summer. CCTB president Don Welsh will head the combined group, which has a goal of raising the number of Chicago visitors by 25 percent (to 50 million annually). But don’t hold your breath: the target date for reaching that goal is 2020.
