Television in Latin America currently includes more than 1,500 television stations and more than 60 million TV sets throughout the 20 countries that constitute Latin America. Due to economic and political problems television networks in some countries of this region have developed less than the North American and European networks, for instance. In other countries like Colombia or Chile, television broadcasting has historically been public-broadcast dominated until the 1990s.[citation needed] The largest commercial television groups are Mexico-based Televisa, Brazil-based Globo and Canada-based Canwest Latin American Group. Due to the shared language of Spanish by two thirds of Latin Americans a lot of programmes and broadcasters operate throughout the region, offering both United States television (often dubbed into Spanish) and Spanish-language television.
