Television in Portugal was introduced in 1956 (test broadcasts) by Radiotelevisão Portuguesa (now named Rádio e Televisão de Portugal), which held the nationwide television monopoly until late 1992. Regular broadcasting was introduced on March 7, 1957. Colour transmissions were introduced on March 10, 1980.
Digital terrestrial television (DTT) was introduced at a very late stage when compared to other countries in Europe and with limited channels. According to the European Audiovisual Observatory it occupies the last place out of the 34 European countries with the weakest offer on digital terrestrial television. Due to this, most Portuguese are subscribers of cable (HFC) or IPTV (DSL or FTTH) platforms, in percentages higher than in the rest of Europe and these platforms are well developed with many channels. During the transition from analog to DTT, subscription-based television services experienced a 10% increase and reached 72.5% of homes in 2012. Outside of the internet, there are no regional or local television channels - with the exception of the autonomous state TV channels, RTP Açores and RTP Madeira -, although a couple of pay TV channels are partly or wholly dedicated to regional matters. Portuguese television is regulated by the Entidade Reguladora para a Comunicação Social (ERC).[2]
