11 milestone facts as NASCAR prepares for 2500th Cup race this weekend – FOXSports.com
When NASCAR started running stock cars in 1949, it deemed the division as Strictly Stock. The following season, the top series was renamed the Grand National Series until Winston became the sponsor in 1971.
The Winston Cup Series lasted from 1971 until 2003 when pressure against the tobacco industry led to NASCAR aligning with telecommunications company, Nextel.
In 2006, Nextel merged with Sprint and the series name changed to the Sprint Cup Series in 2008.
After Sprint announced it wouldn’t renew as the title sponsor, Monster Energy signed on at the beginning of the 2017 season and will be the title sponsor for at least two years.
