Mega is the first private television station to launch in Greece on 20 November 1989 and was the trade name of Teletypos S.A. (Τηλέτυπος A.E.)

The channel regularly achieved the top ratings spot in Greece through its varied programming including comedies, dramas, news, current affairs and entertainment shows.

Examples include the popular Greek comedies Sto Para Pente, Savatogenimmenes and Maria, i Aschimi.

The channel was removed by Digea (the company responsible for digital over-the-air broadcasting in Greece) at 02:08:36 on the morning of 28 October 2018.

On 1 November 2019, the Mega Channel branding, logo and vast program library were put up for auction.

However, on June 27, 2021, the channel retired the 'Mega Mou' branding and began to use a new ident package in which objects form the logo.

Under the ownership of Alter Ego, the channel is now located at 340 Syngrou Avenue, Kallithea, Athens, Greece.
