NASCAR's top division began in 1949 as the Strictly Stock division, was renamed Grand National in 1950, and retained that name through 1970. The Winston era formally began in 1971, when the Public Health Cigarette Smoking Act banned television advertising of cigarettes, prompting tobacco companies to redirect spending into sports sponsorships. R. J. Reynolds signed a landmark deal with NASCAR, and the series was initially called the Winston Cup Grand National Series before dropping "Grand National" in 1986.
RJR's financial involvement transformed the sport. The season schedule was cut from more than 48 events to 31 focused races, eliminating short dirt track events and races under 250 miles from the points schedule. Prize money guarantees were established. NASCAR founder Bill France Sr. passed control to his son Bill France Jr. in 1972, and in 1974 publicist Bob Latford designed a points system that awarded equal points regardless of race length, ensuring the championship would only be decided by drivers who competed consistently across the full season. That points structure remained unchanged until the Chase for the Championship was introduced in 2004.
The Winston Cup era coincided with stock car racing's emergence on national television. The 1979 Daytona 500 was the first stock car race broadcast live from flag to flag on national television in the United States, on CBS, reaching a large captive audience during a major east-coast snowstorm. The closing laps — a crash between race leaders Cale Yarborough and Donnie Allison — and the subsequent fistfight between Yarborough, Allison, and Bobby Allison on live national television gave the sport an indelible dramatic identity.
The 1994 Brickyard 400 at Indianapolis Motor Speedway marked another expansion milestone, bringing NASCAR to one of American motorsport's most storied venues. In 1999, NASCAR signed an eight-year, $2.4 billion television deal with Fox, Turner, and NBC — reflecting the scale of popular interest the Winston era had built.
Winston introduced further marketing innovations, including the Winston Million from 1985 to 1997, which paid one million dollars to any driver who won three of the four most prestigious races in a season. The bonus was claimed only twice: by Bill Elliott in 1985 and Jeff Gordon in 1997.
Through most of the Winston Cup era, the champion was the driver who accumulated the most points over the full season. Points were awarded for finish position, laps led, and leading the most laps, across every race. The system rewarded consistency: a driver who finished reliably in the top ten each week could outscore one with several victories but frequent retirements.
Seven drivers won the Winston Cup championship multiple times. Richard Petty won seven titles between 1964 and 1979. Dale Earnhardt matched Petty's record of seven championships between 1980 and 1994, five of those in the Winston Cup era. Jeff Gordon won four championships between 1995 and 2001, dominating the second half of the Winston era and bringing a new generation of fans and commercial sponsors to the sport.
Throughout the Winston Cup period, competition was contested between American manufacturers: Chevrolet, Ford, Dodge, and Pontiac. Chrysler's Dodge brand departed after 1977 and returned in 2001. Toyota joined the Cup Series in 2007, after the Winston era had ended.
The dominant team operations of the era included Hendrick Motorsports, Petty Enterprises, Richard Childress Racing, and Roush Racing. The manufacturer battle — particularly between Chevrolet and Ford — was central to the marketing story RJR told around the series.
RJR's sponsorship became increasingly controversial following the 1998 Tobacco Industry Settlement, which sharply restricted tobacco advertising including sports sponsorships, creating uncertainty about the deal's long-term viability. During the 2002 season, RJR notified NASCAR leadership that it would terminate its title sponsorship at the conclusion of the 2003 season, one year earlier than planned.
NASCAR's final Winston Cup season was 2003, with Matt Kenseth winning the drivers' championship. The series was renamed the NASCAR Nextel Cup Series beginning in 2004 and has since operated under the Nextel, Sprint, Monster Energy, and (since 2020) plain NASCAR Cup Series names. The Winston Cup trophy and name remained part of NASCAR's cultural heritage, and the era is widely regarded as the period that made stock car racing a mainstream American sport.
Among the 32 different drivers to win the NASCAR Drivers' Championship, the Winston Cup era produced some of the most recognizable names in the sport's history. Richard Petty's final championship came in 1979. Darrell Waltrip won three titles (1981, 1982, 1985). Dale Earnhardt's seven championships spanned 1980 to 1994. Terry Labonte won in 1984 and 1996. Rusty Wallace won in 1989. Alan Kulwicki claimed the title in 1992 in one of the most dramatic championship finales in NASCAR history. Jeff Gordon's four titles from 1995 to 2001 closed the Winston era with one of the sport's most successful careers.
The record of seven championships is shared by Richard Petty, Dale Earnhardt, and Jimmie Johnson, with Johnson achieving that mark entirely in post-Winston Cup eras.
