The original idea came from one Doctor Edwin Turner, ICL Distinguished Fellow, back in 1992. At that time the most important room in the house - where the majority of social interaction between family members took place - was the kitchen.
Ed Turner's idea was to add a computer screen and a bar-code scanner to the front of a fridge and hey presto the idea of online grocery shopping, sharing digital calendars, and the full InterActive Retailing experience was born.
Just see how Oprah's audience reacted to the fridge, all those years ago!
Although the world has changed dramatically since then, families more into multi-screening than social interaction - the ScreenFridge concept is still valid. It's shame that the current iterations are so poor!
