E, Greece
E stands for Epsylon (Έψιλον). It is a supplement to the newspaper Eleftherotypia (Ελευθεροτυπία, lit. 'freedom of the press') which was a daily national newspaper published in Athens, Greece.
Published since 21 July 1975, it was the first newspaper to appear after the fall of the Regime of the Colonels, and for most of its period had been one of the two most widely circulated newspapers in the country. Generally taking a center-left, socialist stance, it was highly respected for its independence and impartiality.
Following the economic downturn in Greece, the newspaper had to file for bankruptcy in 2011. Briefly taken over by a new publisher, lawyer Harris Oikonomopoulos, it was finally shut down in November 2014.
