Blu-ray: not so clear?

I just saw an advert on the side of a bus for the latest Spiderman film – "available on Blu-ray". Blu-ray, of course, is one of the new optical disc formats (the Playstation 3 is shipped with a Blu-ray drive).

However as the word 'Blu-ray' was capped up and written in an unfortunate choice of font, it looked for all the world like Spiderman 3 was "available on BLU-RRY'. Not really the format to be watching high-definition video on...
