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.

Under Section 7/3 of the Act CVIII on Electronic Commerce, which transposes Directive 2000/31/EC, service providers and intermediaries are protected from liability for third-party content. However, this exemption does not cover disguised advertising, as regulated in Section 14/A.

According to Art. 6.2 of Act CXXVIII of 2016, which amends Act XXXIV of 1994 on the Police (and Act C of 2003 on Electronic Communications), telecommunications service providers are required to verify the identity of individuals before entering into a contract for prepaid mobile telephony services (SIM cards). If the identity verification is unsuccessful, the subscription contract cannot be finalised, and the service provider is prohibited from initiating service. Additionally, for contracts exceeding one year, identity verification must be repeated annually on the contract anniversary or through third-party data matching. This identity verification can also be conducted online, either prior to the contract's conclusion or during data reconciliation processes.

Art. 17 of Directive 2019/790 on Copyright in the Digital Single Market (DSM Directive) mandates that providers of content-sharing services seek authorisation from rights holders and implement technical solutions to remove and prevent unauthorised uploads by their users (so-called upload filters), under penalty of losing their liability safe harbour. Further arrangements are envisaged for complaints and dispute resolution mechanisms. Such upload filters are reported to be a significant cost for online platforms. Graduated exemptions are expected to be put in place for new providers active in the EU for less than three years with a turnover under EUR 10 million and with fewer than five million users. The provision is subject to a challenge in the Court of Justice by Poland (C-401/19).
To implement Directive 2019/790, Hungary has adopted Act XXXVII of 2021, therefore making online content-sharing service providers partially liable for copyright violations on their platforms.

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 Hungary, the EU Directive was transposed into domestic law through the amendment of Act CLXXXV on Media Services and Mass Communication of July 2021 (LXIII of 2019 law on the amendment of certain laws related to media services). According to Art. 20 of the Act, at least 30% of the total aggregated length of programmes made available in a given calendar year in the programme schedule of on-demand audiovisual media services must consist of European works, with a minimum of 10% comprising Hungarian works.
Furthermore, pursuant to Art. 136, a media service provider with significant influence that offers a linear audiovisual media service is obligated to allocate 2.5% of its annual advertising revenue to the promotion of new Hungarian cinematographic works. This obligation can be satisfied either through a payment to the Fund or by providing financial support for a new film production, as mutually agreed upon between the Fund and the media service provider.
