According to Home Media Magazine, consumers spent over $60M on Blu-ray titles last week, representing 14% of the home media market. The 167% spike is due in large part to the Blu-ray release of 'The Dark Knight', which is breaking Blu-ray sales records around the world. Comparatively, the previous week, where 'Wanted' was the hot new release, consumers spent $23.64M on Blu-ray.
On the year in whole, consumers have spent nearly $500M on Blu-ray titles, and the average spent per week has been growing as adoption continues to rise.Blu-ray format is growing at a much faster pace than the DVD when it was competing with the VHS.
*These numbers are for America only.
It could be because the DVD got the support of the PS2 after five year of its being introduced in 1995 but the Blu-ray got the support of the PS3 from the starting.
