In Ireland, their second national channel RTE 2 launched in November 1978, and their typical programming on a Wednesday in the autumn of 1979 actually look more tempting than BBC1, BBC2 or Channel TV, below is a typical example of what they would have aired:
NB: RTE 2 did not start their weekday broadcasting schedules in 1979 until 6.50pm.
6.50pm Switch On: Community Announcement
7.00pm This Is Your Life (Imported from Thames Television)
7.30pm Coronation Street (imported from Granada Television, and many episodes behind Britain)
8.00pm Star Trek
9.00pm Botanic Man
9.30pm World Week - RTE current affairs show
10.00pm Porridge (BBC sitcom first airing on Irish television)
10.35pm The Dick Emery Show
11.10pm - Newsnight - RTE Late Night News
11.25pm - Night Light, the epilogue
11.30pm - Transmission Ends
Botanic Man was a Thames TV natural history series presented by David Bellamy, which was shown in the UK during as part of schools television (possibly as well as appearing elsewhere in the schedule). I guess BBC2 might have shown their version a series like that around 9pm, so not completely out of place on a second channel.
