History
OTE was founded on 23 October 1949 as a successor to the Hellenic Telephone Company (AETE), which was established in 1926, with the aim of consolidating all such public and private telecommunications companies. Formerly, telephony, telegraph, domestic and international connections were fragmented and under-coordinated.

Until 1998, the Greek telecommunications market was a monopoly. The market was opened to competitors and OTE was gradually privatized. Along with other telecommunications market providers, OTE is regulated by the National Telecommunications and Post Commission (EETT).
