 In 1990, the Association of Tennis Professionals, led by Hamilton Jordan, replaced the MTC as the governing body of men's professional tennis.They established the ATP Tour, and packaged the nine most prestigious events as the "Championship Series - Single Tournament Week", and beginning in 1996, as the "Super Nine".Twelve of the Grand Prix which were slightly less prestigious than the first nine events were renamed as the "Championship Series - Double Week" (meaning in most cases, 2 of those tournaments occurred the same week), and commencing in 1996, as International Series Gold, while the remaining (approximately 60) became known as the International Series.
