Despite being rebranded as RTP1 on December 25, 1968 to coincide with the launch of RTP2 occupying two hours of their schedule, the logo remained unchanged and in order to distinguish the two channels and though RTP1 was the legal name, the channel had to be identified as I Programa until October 16th 1978.
