Atlanta, 1996
Funded mainly by heavy sponsorship deals, the Americans managed to deflect a lot of the funding away from the tax payer. While steeped in shameless advertising it is considered the model for breaking even.
The main stadium has since been turned into Turner Field (above), home of the local baseball team, to great success. Its legacy is further cemented by $30m of affordable housing built around the site to regenerate poorer districts.
