CNT Tropical

Founded in 1979 by José Carlos Martinez, it was the first station of the Martinez Organizations, and together with TV Paraná (today CNT Curitiba) it formed Rede OM in 1982, which constituted the current CNT. The station was founded as TV Tropical on March 15, 1979, by Oscar Martinez and his sons José Carlos Martinez and Flávio Martinez, through channel 7 VHF. Initially affiliated with TV Globo, it became affiliated with Rede Bandeirantes on December 1 of the same year, when it was emerging as a television network in several states at the time, and when TV Coroados, also belonging to the Martinez family, was sold to Rede Paranaense. TV Paraná de Curitiba, managed by Ronald Sanson Stresser and Diários Associados, is put up for sale due to the conglomerate's financial crisis. The Martinez Organizations then offer themselves as buyers of the station. After intense negotiations, the station was finally purchased in April 1980, and became part of a small local network with TV Tropical. On July 18, with the end of Rede Tupi, TV Paraná unifies its affiliation with TV Tropical and both become affiliates of Rede Bandeirantes. In May 1982, when the Martinez Organizations concluded the restructuring phase at TV Paraná, Rede OM was officially founded, with the Curitiba broadcaster becoming the network head.
