CNT Tropical is a Brazilian television station based in Londrina, a city in the state of Paraná.

[1] TV Paraná de Curitiba, managed by Ronald Sanson Stresser and Diários Associados, is put up for sale due to the conglomerate's financial crisis.

After intense negotiations, the station was finally purchased in April 1980, and became part of a small local network with TV Tropical.

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.

After the creation of the network, TV Tropical expanded its coverage area to several cities in the interior of Paraná, with the installation of microwave repeaters.
