Knight-Ridder Predicted Apple Tablet in 1994: Didn’t Build It
Hindsight is 20-20, they say. Take, for instance, this promotional video from media company Knight-Ridder made in 1994, in which the Knight Ridder laboratory predicts newspapers being replaced by sleek black tablet devices that allow people to consume media on the go.
Did Knight Ridder foresee the Amazon Kindle and Kindle DX? Or perhaps the inevitable tablet renaissance that will be sparked by Apple’s upcoming launch of a tablet device? Mashable reader Christoph drew our attention to this wonderful archive clip, which does indeed feature a device that’s virtually identical to the Apple tablet mockups we’ve been seeing.
Why did the project fail to get off the ground? Screen technology, said former Knight Ridder laboratory head Roger Fidler in an interview earlier this year – screens were too heavy and sucked too much power.
