In the days before the Internet went mainstream, two text-based services provided an innovative mix of interactive media to millions of people across Britain through their televisions. Despite BBC's Ceefax and ITV and Channel 4 Teletext being outmoded by the Web and then switched off as TV went digital, they still live on in a nostalgic part of people's hearts – a place (re)visited by a group of artists exhibiting at the second International Teletext Art Festival in Berlin.

Despite offering a resolution lower than most smartphones that breaks down into 80 x 72 grid of characters (letters, numbers and a few icons), teletext services offered a wealth of services. Designers at the service used very-basic-indeed tools to make pictures, tables and diagrams – allowing them to create comparatively complex presentations of news stories, weather reports, games (including the much-loved Bamboozle, recently recreated as a popular iPhone app), horse racing data for bettors and even sell holidays.
