Quick Summary

The National Tennis League (NTL) was an American sports organization founded in 1967 by George MacCall, former U.S. Davis Cup captain. It was one of two new professional groups formed that year, alongside World Championship Tennis (WCT). The NTL, along with WCT, signed a significant number of top professional and amateur players, contributing to the eventual shift towards open professionalism in tennis. This era marked a move away from the "shamateurism" that had characterized professional tennis for decades, where leading players received substantial payments "under the table". The NTL's formation was a key development that pushed the International Lawn Tennis Federation (ILTF) to approve open tournaments, which officially began in 1968.1
