Can Avatar beat DVD?

With the release of James Cameron's blockbuster Avatar, sales of BluRay discs have seen a massive boost.

"Since its launch on Monday, Blu-ray copies of Avatar have been flying off the shelves. It looks set to smash all sales records for the new format, as it did in the US, where it sold a phenomenal 2.7 million copies in just four days.

Its release comes as some retailers, including HMV, are seeing Blu-ray sales outstrip DVDs for the first time."

Experts are stating that we may be at the tipping point which will see BluRay really take off in the UK.

"But is Blu-ray ready to have its day, or is this just another play from an industry frantically trying to keep people paying for its product? Is the format truly revolutionary, or is it just the MiniDisc of movies?"

Personally I believe that BluRay is destined to take place as the dominant format, but there are factors that still need to be dealt with. The cost of films on BluRay upon release is usually around £20 at the present day, whilst DVDs are usually around half the price. Also, a BluRay player requires a HD TV. I think that most households only own one main HD TV today, meaning that these films would only be able to be viewed in one place.
Sony's PlayStation 3 console is the first games unit to be compatible with BluRay discs, and still, this has not really given the format a dramatic boost. PlayStation 3 consoles are more expensive than their rivals Xbox 360, which just play DVDs discs.
Technology is always being advanced and bettered. The next step ahead is high definition, which I think will have a firm dominance in households quite soon, in the form of BluRay.
