Gruppo TIM, legally TIM S.p.A. (formerly Telecom Italia S.p.A.), also known as the TIM Group in English, is an Italian telecommunications company with headquarters in Rome, Milan, and Naples, (with the Telecom Italia Tower) which provides fixed telephony and DSL data services.
It is the largest Italian telecommunications services provider in revenues and subscribers. It was founded in 1994 by the merger of several state-owned telecommunications companies, the most prominent of which was Società Italiana per l'Esercizio Telefonico p.A., (known as SIP), the former state monopoly telephone operator in Italy.
The company's stock is traded in the Borsa Italiana. Since 2017, the Italian State exercises on TIM the "Golden Power", which allows the government to take a number of actions when the strategic interests of the country are concerned.
