It is the largest capacity sports venue of any variety worldwide, with a top capacity of some 257,000+ seated spectators. NASCAR was founded by Bill France Sr. on February 21, 1948, with the help of several other drivers of the time. The first NASCAR "Strictly Stock" race ever was held on June 19, 1949, at Daytona Beach, Florida, U.S..
