When did Sábado Gigante first air?
Sábado Gigante
Sábado Gigante (English translation: "Giant Saturday" or "Gigantic Saturday"; known officially as Sábado Gigante Internacional outside Chile) was a Spanish-language television program broadcast by Spanish International Network in the United States. It was also Univision's longest-running program and the longest-running television variety series in history.[2] Sábado Gigante is an eclectic and frenetic mix of various contests, human-interest stories, and live entertainment. From its start in 1962, it was hosted by Chilean TV star Mario Kreutzberger under the stage name of Don Francisco. Rolando Barral began serving as a co-host in 1986; that role was taken over by Javier Romero in 1991.
Programadora
 In 1997, Colómbia awarded two private television licenses to Caracol and RCN, two of the largest "programadoras"; their channels took to the air on July 10, 1998. Some 25 "programadoras" still applied for spaces on the two channels in the "licitación" of 1997, however, including Caracol and RCN which had limited spaces on the two major channels from January–July 1998. However, Caracol and RCN enjoyed limited output; notably, Caracol was left without any timeslots on Saturdays. Other "programadoras" presented Caracol's marquee programs on that day, the "Premier Caracol" movie (Andes Televisión and the revived CPT) and the long-running "Sábados Felices" variety show (Coestrellas/CPS/Proyectamos Televisión).
