In 1967, with the Excelsior crisis, TV Gaúcha joined Rede Globo, founded in 1965 by journalist Roberto Marinho in Rio de Janeiro.

On June 12, 1972, TV Gaúcha suffered a fire at its headquarters in Morro Santa Teresa, damaging many equipment and studios, a great loss for the station.

In 1982, the Galpão Crioulo program, lasting 50 minutes, was broadcast with the aim of disseminating gaucho folklore and nativist music.
