Some sports betting services in Ohio are breaking the rules

Starting January 1, sports betting will become legal in Ohio. Companies will be able to open their brick-and-mortar sportsbooks and operate sportsbetting apps. The Ohio Casino Control Commission warns them to be cautious of breaking the state's core tenets in advertising campaigns.

The control commission has asked companies to review their gambling ads to avoid future fines or legal action. The commission's rules prohibit companies from promoting sports betting products to under-age people. One alleged violation was during a live broadcast of The Barstool College Football Show on the University of Toledo campus last month. The broadcast included an advertisement read live for the BarStool Sportsbook, which is owned and operated by Penn Interactive. It violated the state's gambling rules. Sports betting is legal in Ohio. Professional sports teams like the Cincinnati Reds and Bengals can partner with gambling companies.
