Televisió de Catalunya (Catalan pronunciation: [tələβiziˈo ðə kətəˈluɲə], known by the acronym TVC) is the public broadcasting network of Catalonia, one of the seventeen autonomous communities of Spain. While the main language of all these channels is Catalan, Spanish is usually neither sub-titled nor dubbed, as it is generally accepted that all Catalan speakers are by default also Spanish speakers. Some programmes such as Polònia and APM use Spanish extensively, largely for effect. In the Aran Valley, there are programs in Aranese.
