The story
In 1993, Globosat split its content generation and distribution businesses. Cable TV sales and distribution were assigned to Net Brasil, which was also responsible for installing cable networks in selected cities. Nowadays, NET, which was succeeded by Claro Brasil's TV operations, is responsible for the cable network programming in those cities as well.
In the later years, content production and programming remained with Globosat, was later renamed to Canais Globosat. Globosat also operated a channel in Portugal, TV Globo Portugal (part of TV Globo Internacional), having earlier operated a similar channel, GNT Portugal, until 2006.
In late December 2019, Globosat was shut down as a separate company, and on January 1st, 2020, Globosat's remaining assets later merged with other selected Grupo Globo subsidiaries to form a single company named Globo as part of the "Uma Só Globo" reorganization. The Globosat brand lasted until September 2020, when it was officially discontinued following the rebranding of Globosat Play to the Canais Globo application.
