After a lapse of more than four decades, tennis was reintroduced to Olympic Games spectators as one of two demonstration sports.

For the demonstration sports—fronton and tennis—the following installations were employed. In Mexico City: Frontón México, fronton and tennis courts of the Chapultepec Sports Center, fronton courts of the Asturian Sports Center, the Lebanese Sports Center and the Frontón Metropolitano. In other cities: fronton courts of the Acapulco Jai-Alai; and the tennis courts of the Guadalajara Country Club, the Atlas Sports Club and the Guadalajara Sports Club, all in the city of Guadalajara
