But interestingly, it also marks another landmark, for analogue carried something else alongside the television pictures and sounds that we all enjoyed. It also carried a teletext service.
Ceefax was launched in 1974 and was the worlds first teletext service. Containing graphics and text it rotated on a sequence of pre-delivered pages and you could get News, Sport, Recipes and Holidays to name just a few.
The system was fast, but limited because of it's "one way" delivery. This was challenged when the Internet became more popular, and people would only use it to check the football scores while visiting the grandparents!
Now replaced by "the red button", the digital service is able to offer a lot more, including additional video content and information to make the viewer experience more enjoyable.
So we thank you Teletext, we thank you Ceefax, for bringing on tap information to the masses. We will miss waiting for the scrolling pages to bring us the news we want to read. Silently you will disappear as the analogue transmitters are finally shut down.
And as you take a bow as the final curtain closes, please make sure you don't get run over by the super fast broadband as it whizzes past.
