Kentucky Off-Track Betting Corp., owned by four of the state's racetracks, celebrated its 10th anniversary with total handle of $313 million through June 30. The corporation was formed in November 1992.Churchill Downs, Ellis Park, Keeneland, and Turfway Park own Kentucky OTB, which now operates four parlors in smaller cities in the state: Corbin, Jamestown, and Pineville in southeast Kentucky, and Maysville in northern Kentucky on the Ohio border.The facility in Corbin is located not far from Tennessee, which has no legalized gambling. The parlor has handled $110 million--almost a third of Kentucky OTB's total handle--since its inception."Kentucky Off-Track Betting is happy to bring the excitement of simulcast racing to cities that aren't located near a live racing facility," said Laura Prewitt, general manager of Kentucky OTB. "We have a strong patron base."During the past decade, wagering at the OTB parlors has produced $19 million for purses. In addition, 1% of handle at the parlors goes to the cities and counties in which they're located. Kentucky OTB has more than 50 employees. A 10-year anniversary celebration is planned from July 27-Aug. 2. Patrons will receive free programs, betting vouchers, complimentary food, and free admission. There will also be a handicapping contest and prize giveaways.
