Telesp

Telesp - Telecomunicações de São Paulo S.A. (in English: Telesp - São Paulo Telecommunications) was the telephony operator company of the Telecomunicações Brasileiras S.A. (Telebrás) system in the Brazilian state of São Paulo, successor to the CTB, later incorporating the Companhia de Telecomunicações do Estado de São Paulo (COTESP) and other smaller companies. It remained in operation from May 1973 until the privatization process in July 1998, when it was acquired by the Spanish company Telefónica, forming Telefônica Brasil, which in 2012 adopted the Vivo brand for its fixed-line operations.

Of the current 645 municipalities of the state of São Paulo, Telesp operated in all but 43, which were served by the companies CTBC Borda do Campo, CTBC Brasil Central and CETERP.
