The US Festivals were two early 1980s music an culture festivals sponsored by Steve Wozniak of, at the time, Apple, Inc., and broadcast live on cable television. The first was held Labor Day weekend in September 1982 and the second was Memorial Day weekend in May 1983. Wozniak paid for the bulldozing and construction of a new open-air field venue as well as the construction of an enormous state-of-the-art temporary stage at Glen Helen Regional Park in San Bernardino, California. (This site was later to become home to Blockbuster Pavilion—now Hyundai Pavilion—the largest amphitheatre in the United States as of 2007.)
