Double-sided Blu-ray / DVDs: why so long?

January 19, 2010 for sale for the first time there will be double-sided discs, on one side of which is Blu-ray, and on the other - DVD. Such discs were ordered by Universal for the Bourne trilogy. The discs will sell for $ 29.98 - even cheaper than regular Blu-ray, although more expensive than DVD.

This is a great idea, because Blu-ray can not get widespread because of the vicious circle of "few devices -> few movies -> there is no point in buying a player." In addition, some do not specifically buy the movie in high resolution, because the Blu-ray player is installed only at home, whereas in a laptop / car, for example, a regular DVD. Double-sided discs should solve this problem.

The demand for a new product is also indicated by the immense popularity of combined packages, where two disks are sold in one box: DVD and Blu-ray. Compared to them, the bilateral option is still more convenient (and potentially cheaper).

It is interesting to recall that in the extinct HD DVD format, such double-sided discs appeared in 2007 . It's incredible that it took Blu-ray almost three years to adopt a good idea.
