The Swedish National Archive of Recorded Sound and Moving Images (SLBA) collects the Swedish output of audiovisual media: broadcast radio and TV, film, video, records, CDs, multimedia. The archive also collects older items, with the ultimate aim to cover the entire national production of recorded sound and moving pictures from the 1890s and onwards. By including the radio and TV broadcasts into the Swedish Law of Legal Deposit Copies, Sweden became probably the first country to officially highlight the importance of audiovisual media as source material for research.
