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 Croatia, the EU Directive was transposed into domestic law through the amendment of the Electronic Media Act of October 2022 (Official Gazette 114/2022). According to Art. 27 of the Act, 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 prominently displayed on the front page of the catalogue. Additionally, service providers are required to invest 2% of their total annual gross income in the production of Croatian audiovisual works by independent producers or to purchase Croatian audiovisual works from such producers. Providers are also obliged to maintain and progressively increase the share of European works in their programme catalogues.
Furthermore, Art. 6.3 of the Rules on the Criteria and Manner of Increasing the Scope of the Share of European Works stipulates that service providers with catalogues containing more than 20% but less than 30% European works must raise this share to at least 30% within two years. The increase must be gradual, with providers achieving at least 25% in the first year after obtaining their licence and a minimum of 30% by the second year.

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.

Those aspects are provided in Arts. 16-18 of the Act on Electronic Commerce. In addition, Art. 19 contains an exemption for hyperlinks made available by the service provider.
