pc 1 mentioned in another thread the Classic series of 1970 and 1971, which was a one of a kind series of challenge matches for 10.000 $, which were only for the winner, while the loser got nothing. At the begin of the tennis boom, promoters like McCall, Hunt and Podesta tried to gain public support and attention on the US tv market, by using new experimental formats (or better by going back to formats used on the old pro tour). The best 10 pros of the year before were sampled. The series was played at the big indoor venues of the USA, like Madison Square Garden, Philadephia Spectrum, Boston Garden and others. The format was a bit strange, basically it was a round robin, the winner would take the next challenge by a player next in line, the winner of that match would face another challenge and so on. The loser could qualify in a qualifying match for one of the next challenges. The best four players of the competition would play a semifinal and final at Madison Square Garden, the winner of the final would get 35.000 $. In all, some 210.000 $ were on the line, an unheard sum in those days, far and away more money than to win on the majors circuit. The Wim winner got some 6.000 $.
