The Network Three thing is complicated by the looks of it. In 1965 it became an all 'music programme' with sport at times, but there was still a sequence called 'The Third Programme'. The Genome listings for Network Three continue up to the launch of Radio 3, so presumably it was a blanket term for everything in those frequencies - the music programme, sport and the Third.
It is indeed all very complicated, something I've tried to get my head round it several times. Presumably even the Genome team couldn't get their heads round it, because although they use the name 'Network Three' right up until 1967, it doesn't actually appear in editions of the Radio Times after 1963. Instead, 'Third Network' is used as the overall title for all services on that frequency from 1963-67.
Network Three was introduced in 1957 on the Third Programme frequencies as a service of programmes covering minority interests, hobbies, education and some music. Radio Times, as already mentioned, listed the two services separately.
However at some point in 1963, the name 'Network Three' disappeared, and 'Third Network' now appeared as an umbrella title for all services carried on that frequency, which also included Sports Service on Saturday afternoons.
But to make things more confusing, 'Third Network' doesn't appear to be simply a renaming of 'Network Three' - the former refers to all services on the frequency
including
the Third Programme, while the latter refers to all services
other than
the Third Programme. Indeed, I have a Radio Times from April 1963, where the Saturday listings are headed up 'In the Third Network', while 'Network 3' is used the rest of the week. Some time after the demise of the Network Three name, from Dec 1963 the early evening minority interest programmes were grouped together as 'Study Session'.
Then as if things weren't confusing enough, in 1964 yet another service began on the frequency, the 'Music Programme', which was a daytime service of classical music, initially on Sundays only and then extended to seven days a week by the end of the year.
So it was the Third Network (rather than Network Three or the Third Programme) that was renamed Radio 3 in 1967, with the separate headings of Third Programme, Music Programme, Study Session and Sports Service remaining until April 1970.
I'm sure that's all as clear as mud.
