Hard Rock is a chain of theme restaurants founded in 1971 by Isaac Tigrett and Peter Morton in London. In 1979, the cafe began covering its walls with rock and roll memorabilia, a tradition which expanded to others in the chain. In 2007, Hard Rock Cafe International (USA), Inc. was sold to the Seminole Tribe of Florida and was headquartered in Orlando, Florida until April 2018 when the corporate offices were relocated to Davie, Florida. As of July 2018, Hard Rock International has venues in 74 countries, including 185 cafes, 25 hotels, and 12 casinos.
