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. Art. 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 by facilitating access to such works using any appropriate means to ensure their prominence. The Directive has been implemented by Member States in different ways, ranging from very extensive and detailed measures to a mere reference to the general obligation to promote European works.
In Greece, the EU Directive was transposed into domestic law through Law 4779 of 20 February 2021. According to Art. 17 of the law, providers of on-demand audiovisual media services must ensure that at least 30% of the works in their catalogues are European and that these works are given prominence. These providers are required to report to the National Audiovisual and Communications Center (EKOME SA) each June on their compliance with these obligations for the previous year. Additionally, audiovisual service providers located in other Member States that offer services to consumers in Greece must annually contribute an amount equal to 1.5% of their turnover related to their activities in Greece. This amount is designated for the production of Greek audiovisual works, the purchasing of licenses for Greek audiovisual works that have not yet been distributed, or it may be paid to EKOME SA for funding Greek productions.

Under the EU 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 that implemented the Directive have been overturned. The Greek law implementing the Directive is still in place. Art. 6 of Law 3917/2011 goes even further in the implementation of the Data Retention Directive by requiring that retained data on ‘traffic and localisation’ stay ‘within the premises of the Hellenic territory.’

Art. 47 of Law 4002/2011 requires that data relating to the conduct of online gambling, as well as data exchanged between a player, licensee, internet service provider and financial institutions relating to such games, are stored in servers located in Greece for a period of 10 years.

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 harbour. 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 the E-commerce Directive in Greece almost verbatim. 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 Art. 8 of Law 2251/1994 on consumer protection. One considerable exemption to the no-liability rule is the field of data protection.
