The EU Directive on Audiovisual Media Services (AVMS) covers traditional broadcasting services as well as audiovisual media services provided on-demand, including via the Internet. Article 13(1) provides for member-states to secure a minimum 30% share of European works in the catalogues as well as "ensuring prominence" of those works. "Prominence" involves promoting European works through facilitating access to such works using any appropriate means to ensure prominence of European works.
Art. 17 of L. 4779/2021 provides that providers of on-demand audiovisual services must ensure that their catalogues contain European works at least in 30% and that they are prominently displayed. In addition, audiovisual service providers that are located in another member-state and address their services to consumers in Greece are obliged to annually contribute an amount equal to one and a half percent (1.5%) of their turnover related to their activity in Greece for the production of Greek audiovisual works or for the purchasing of licenses of Greek audiovisual works that have not yet been distributed or to pay that amount to the National Audiovisual and Communications Center S.A. for the funding of greek productions.

The Directive 2000/31/EC (E-Commerce Directive) is the legal basis governing the liability of Internet Services Providers (ISPs) in the EU Member States and includes a conditional safe harbor. Not all Member States have transposed the relevant articles consistently, leading to divergent national case law that could cause legal insecurity on an EU level.

The Greek Presidential Decree 131/2003 implements almost verbatim the E-commerce Directive in Greece. The provisions in this Decree are considered to exempt the ISPs from every liability (civil, penal, administrative), even the severe liability of service providers according to article 8 of Law 2251/1994 on consumer protection. One considerable exemption to the no-liability rule is the field of data protection.

Under the Directive on Data Retention, operators were required to retain certain categories of traffic and location data (excluding the content of those communications) for a period between six months and two years and to make them available, on request, to law enforcement authorities for the purposes of investigating, detecting and prosecuting serious crime and terrorism. On 8 April 2014, the Court of Justice of the European Union declared the Directive invalid. However, not all national laws which implemented the Directive have been overturned. The Greek law implementing the Directive is still in place. Specifically, Article 6 of Law 3917/2011 requires that data be retained for a period of 12 months and it needs to be retained within the Hellenic territory.
