The rivalry between Nintendo and Sega was described as one of the most notable console wars in video game history,[44] in which Sega positioned the Genesis as the "cool" console, with games aimed at older audiences, and aggressive advertisements that occasionally attacked the competition.[45] Nintendo scored an early public-relations advantage by securing the first console conversion of Capcom's arcade hit Street Fighter II for Super NES, which took more than a year to make the transition to the Genesis. Though the Genesis had a two-year lead to launch time, a much larger library of games, and a lower price point,[46] it only represented an estimated 60% of the American 16-bit console market in June 1992,[47] and neither console could maintain a definitive lead for several years. Donkey Kong Country is said to have helped establish the Super NES's market prominence in the latter years of the 16-bit generation,[48][49][50][51] and for a time, maintain against the PlayStation and Saturn.[52] According to Nintendo, the company had sold more than 20 million Super NES units in the U.S.[53] According to a 2014 Wedbush Securities report based on NPD sales data, the Super NES outsold the Genesis in the U.S. market by 1.5 million units.[54]
