The company was originally formed as part of Telebrás, the state-owned telecom monopoly at the time. In 1998, Telebrás was demerged and privatized. Telefónica bought Telesp, the São Paulo division, and rebranded it to Telefónica. On 15 April 2012, 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).
Vivo owns the following brands:
The Vivo brand was launched on 13 April 2003, as a mobile phone service provider. It's the largest provider in Brazil with over 76 million users. It originated from the merger of several Brazilian mobile phone operations under a joint-venture owned equally by Portugal Telecom (PT) and Spain's Telefónica. Until 2006, the group was composed of six holding companies which, as announced in November 2005, merged into a single holding company, Vivo Participações S.A.. The operation was concluded on 22 February 2006. In July 2010, Telefónica bought PT's shares.
Most of its network was initially based on IS-95, though there were parts of it that were still analog AMPS and parts (resulting from acquisition of other companies) using TDMA (IS-136). These are all being converted to GSM since 2006, when, after years being the only CDMA network, Vivo announced a GSM network, and that it would operate in both CDMA and GSM. The CDMA network was gradually converted to CDMA2000 in the major cities. All CDMA network was discontinued on November 2012
The following operators merged to form Vivo:
Owned by Portugal Telecom
Owned by Telefónica
