More from the history of teletext as defined by weather forecast pages.
This map from Oracle in 1977 displays a possible weathermap layout for a regional forecast. To my knowledge nothing like this was ever implemented and the test status of the page is indicated by the text: "regional weather forecast could use maps like this one".
And this is the national weather map from the same page set. Note the colour clash and different map to the Ceefax one.
This is a humorous map from an Oracle page in 1989. This must have been phased out pretty quickly as I don't remember it. The humour seems to have largely gone from commercial teletext - it has become serious.
2000s, an interactive TV map from Teletext including television icons. Note the JPEG advertisements.
Compare this to a 1996 televised broadcast of the weather including a satellite image of Britain. On teletext, Michael Fish's place is taken by some text.
