San Francisco 49ers
The team was founded in 1946 as a charter member of the All-America Football Conference (AAFC) and joined the NFL in 1949 when the leagues merged. The 49ers were the first major league professional sports franchise based in San Francisco. The name "49ers" comes from the prospectors who arrived in Northern California in the 1849 Gold Rush. The team is legally and corporately registered as the San Francisco Forty Niners. The team began play at Kezar Stadium in San Francisco before moving across town to Candlestick Park in 1970 and then to Levi's Stadium in Santa Clara in 2014.
Logos and uniforms of the San Francisco 49ers
From the 1980s until 2005, the 49ers nearly always wore their white uniforms at home for their two preseason home games (and thus usually wore white jerseys the whole preseason,) while the team wore red for all eight regular season home games. Since 2006, the 49ers have worn red jerseys for all home games including preseason. The team also is occasionally compelled to wear red on the road when visiting warm-weather opponents early in the season (if that opponent elects to wear their white jerseys), or if an opponent's established home jersey is white, such as the Dallas Cowboys (and on most occasions the Washington Redskins and Miami Dolphins).
