In five years, Blu-ray has certainly broken through and achieved the market penetration and consumer awareness that the format needed to survive. Had the format war with HD-DVD not been rectified and both formats hobbled on, this certainly would not have occurred. A visit to your local video shop or retailer is indicative of the strength of support that exists for the format. Retail stores simply won't invest in floor space when money is not being returned. That the Blu-ray section at my local JB Hi-Fi grows larger and larger every time I visit is evidence that the format is not going anywhere.
Despite this, there exists some media commentators and certain companies with vested interests who downplay the success of Blu-ray and insist that other technologies will soon surpass it. This is grossly exaggerated at best, and woefully misguided at worst. The truth is, Blu-ray is here for the long haul. It will continue chipping away at the market share of DVD until the lustre of the format is well and truly depleted.
