Vivo formerly known as Telefonica Brasil, is the second largest telecommunications company in Brazil. It is headquartered in São Paulo.
The company was originally formed as part of Telebrás, the state-owned telecom monopoly at the time. In 1998, Telebrás was demerged and privatized, with Telefónica taking Telesp. Telesp was rebranded as Telefonica from 1998 until April 15, 2012, when all Telefonica services were rebranded again to Vivo, using the same strategy of unifying all its services in a unique brand, like Movistar (Hispanic America and Spain) and O2 (rest of Europe). Currently, the Telefonica brand is only used for the group Telefónica Brasil.
