NASCAR's showcase series. Launched in 1949 as Stricktly Stock, it was renamed Grand National for 1950. In 1971, Winston came on board and the Winston Cup was born. Government regulations forced Winston out after 2003, and the series was known as Nextel Cup from 2004-07, and has been known, after a corporate takeover, as Sprint Cup since 2008. I tend to just call it Cup. By far my favorite series, and the most popular series in scale.
