AT&T: do monopólio privado à concorrência com serviços de streaming e os desafios da regulação.

The article covers the history of AT&T, from the emergence, in the 19th century, from the private monopoly to its collapse in the 20th century, and the restructuring to maintain its dominance in the 21st. In the latter, the trajectory culminates in the merger with WarnerMedia, to face competition with audiovisual streaming services. The article uses the theoretical contribution of the Political Economy of Communication (EPC), in addition to the framework on Network Neutrality, to understand the undoing of this merger, followed by the joining of WarnerMedia with Discovery. It ends with experiences regulating streaming services and challenges to reduce regulatory asymmetries. [ABSTRACT FROM AUTHOR]
