Mull was connected to the mainland by a submarine telegraph cable between Oban and Grass Point in 1871. There were telegraph offices at Tobermory, Dervaig, Calgary, Craignure, Pennyghael, Tiroran, Fionnphort, Bunessan and Iona.
The Post Office built an experimental wireless telegraph station on Meall an Inbhire near Tobermory in 1892.
AM radio, broadcast from Oban, came to the island in 1930 and television in 1954. New AM radio and UHF television transmitters were constructed on Druim Mòr, 1 mile west of Torosay Castle, in 1978. Digital transmissions commenced on 15 November 1998 and analogue transmissions ceased on 27 October 2010. The digital transmitters have 21 relays on Mull, surrounding islands and parts of the mainland. They are collectively called the Torosay Transmitter Group.
