1884 The Telegraph Construction and Maintenance Co manufactured cable for the Eastern Telegraph and Eastern Extension Companies which was laid to connect all the islands of the Grecian Archipelago and in trans-Indian waters. During the year a new ship, the Magneta, was added to the cable fleet of the Eastern Extension Company.
1897 The Spanish Government would subsidise the Eastern Extension Telegraph Company to connect its system to Iloilo, by laying three short cables between Luzon, Pannay, Negros, and Cebu. Extensions of the system had been in the Philippine Islands and in Netherlands Indian territory. There had been duplexing and triplicating of existing cables as well as widening of the area covered by the company.

1913 Laid a cable from Colombo to Penang; the Eastern Company would lay a cable from Aden to Colombo to connect with it
1928 The communications methods of the British Empire were merged into one operating company because of increasing competition for cable telegraph companies from companies using radio communications. The British Government formed the Imperial and International Communications Ltd to carry out these operations, which incorporated the Eastern Extension Co amongst others.
