From the Amazon.co.uk Associates Blog, something to bear in mind if you’re considering buying a gigantic TV for Christmas:

“It's easy for your customers to get drawn in by larger screens at bigger prices, but bear in mind that eight feet is the minimum recommended viewing distance for a screen of 32 inches, which is about the maximum the average living room can accommodate. 40-inch-plus screens may be nice for keeping up with the neighbours, but the viewing experience will be inferior if sitting too close. The other advantage of sticking to 32 inches is the resolution. At this size there is no visible difference between 720p and 1080p whatsoever; if your customers are forking out for 1080p on anything less than a 40-inch screen, they are throwing their money down the drain no matter how many sales people tell them otherwise!”
