BBC Two continued to show a DOG
during the Learning Zone until that was axed, most likely for students to know that the Learning Zone is on BBC Two if they want to record it themselves.
The Learning Zone ended up as being totally unique branding wise because it rebranded in 1997 with everything else and then didn't change when BBC Two changed its look in 2001 and 2007. It ultimately ended up being the last bastion of the 1997 look, still running and looking good in 2015 when the service was sadly eventually scrapped.
And in any event, anybody who knew about the Learning Zone didn't need a DOG on the broadcast to tell them; you could order a pretty guide to the programming on the Zone from the BBC directly as a mailshot because there wasn't enough room in TV guides to list it all (this was in the days before we had on screen EPGs
The DOG was there to signal that the recording came off air and try and prevent people from selling the broadcasts to other institutions I tthink. Bear in mind that a complete set of videos at the time could have cost a reasonable amount.
The learning zone was amazing with the way nobody really touched it from 1997 until 2015, with just updated graphics being used rather than completely fresh ones. Even the menu template stayed the same. I kind of miss it.
Oh it's such a perfect day, I'm glad I spent it with you...
