The Balloon Fiesta grew each year for decades, and today is the largest balloon convention in the world. The number of registered balloons reached a peak of 1,019 in 2000, prompting the Balloon Fiesta Board to limit the number to 750 starting in 2001,[3] citing a desire for "quality over quantity". The limit was changed to 600 in 2009 — citing recent growth in the city and a loss of landing zones. On any given day during the festival, up to 100,000 spectators may be on the launch field where they are provided the rare opportunity to observe inflation and take off procedures. Countless more people gather at landing sites all over the city to watch incoming balloons.
