I actually purchased TV Times in London in 1990 (still have it around here somewhere) and I am familiar with the format. IIRC they listed the main channels but placed special emphasis upon ITV.What you're seeing here is one of the localized editions of TV Times, which was the program magazine of all the ITV franchisees.
You had to buy both TV Times from ITV and Radio Times from the BBC to get listings for both commercial and BBC TV. It wasn't until the 1970s or later that listings magazines came out in the UK showing all channels.
Each ITV region had its own edition of TV Times, since programming was so varied among the regional operators.
