The festival was originally run by the City of Seattle. It adopted the name Bumbershoot in 1973; for its first two years, the festival was known as Festival '71 and Festival '72.
Admission was free until 1980, when One Reel took over production duties from the city. The city stopped financing the festival in 1995. In 2007, Bumbershoot will run from September 1-3. Non-discounted ticket prices are $35 per day or $95 for all three days.
