The 1970s saw Topps go largely uncontested in the sports card market. The decade featured full runs of baseball, football, basketball, and hockey. Aside from issues like Kellogg's cereal premiums which ran throughout the 70s there was not much in the way of major national card manufacturers to compete with. Topps maintained its license agreement with O-Pee-Chee in baseball and hockey. The company would have significantly more ground to cover given the growth of the professional sports leagues during the decade. Major League Baseball added four new teams in 1969 and two in 1977; the National Football League added two teams in 1976; the National Basketball Association gained three in 1970, one in 1974, and the American Basketball Association picked up one in 1972; the NHL acquired two teams in 1970, 1972, and 1974. Soccer also made the Topps roster in the 70s, producing English and Scottish 'Footballers' for distribution in the United Kingdom. Domestic soccer was not to be forgotten with a North American Soccer League sticker set in 1979. The following are trading card sets issued by Topps in the 1970s. All cards listed are standard size (2½ × 3½ inches). Exceptions are noted.

In the late 1970s, Topps produced promotional sets for Burger King fast food restaurants, Procter & Gamble and NBC.
The next year, Topps produced for Burger King issued sets of New York Yankees, Detroit Tigers, Houston Astros, and Texas Rangers for distribution at outlets in the home areas of the teams. The cards were almost identical (the photo area is slightly larger) to the 1978 Topps regular issue cards Some of the players had a different photo than their Topps counterpart including some who have changed teams, most notably the Yankees Goose Gossage. Also of note are single rookie cards for the Tigers Jack Morris, Alan Trammell, and Lou Whitaker, who all appeared on multiple player rookie cards in the Topps set. As with the previous year, only the checklist card featured any Burger King branding.
