It was officially launched in early 2006 as part of the digital television transition mandated by the European Union.

The programming on the four digital channels was separate and distinct from that featured on ERT's three traditional analogue services - ΕΤ1, ΝΕΤ and ΕΤ3.

ERT Digital was available to approximately 65% of the population, mainly in Athens, Thessaloniki and some other major cities.

It broadcast free-to-air without any subscription cost, requiring only a generic DVB-T set-top box.

RIK Sat was also offered on the same frequency, accounting as the temporary fourth channel of the bouquet.
