foreign licenses and are legally treated as rebroadcasts of foreign channels. As such, they don't need to follow this requirement and may use a different rating system instead. Portugal RTP introduced DOGs in the late 1980s, when it was the only broadcaster in Portugal that operated two television channels. Initially, the logos were placed on the top-right corner, but in 1991 they were moved permanently to the top-left corner, to allow television ratings to be shown in the top-right corner. Until 2004 and RTP1's rebranding, their DOGs were placed on the bottom-left corner during newscasts. On some programs or live sport broadcasting, DOGs are placed in the top-right corner. Logos are removed during advertising breaks and trailers. For subtitle information, on RTP1 and RTP2 a number such as 884, 885, 886, 887 or 888 is placed near the logo; in other cases Direto (Live) is sometimes used instead of a number (some programmes use neither numbers nor Direto (Live), Gravado (Recorded) or Repetição (Repetition)).

This channel along with Acasă TV (nowadays called Pro 2) and Pro Cinema had also the DTH provider logo in the top-right corner, on the transmissions from these DTH platforms, to prevent CATV piracy. The top left corner is also used by national commercial station Kanal D, as well as smaller national TV stations like National TV and Prima TV. Note that the Pro network channels
