Research conducted by 'HomeMediaResearch' has compared the consumer sales of DVD and Bluray products in the US. The comparison was conducted during 2009 and compared sales to the previous year. The research highlighted that Bluray sales had doubled whereas DVD sales had slumped by nearly eight percent. The technical superiority of Bluray is without question, the debate is whether Bluray sales will ever overtake DVD.

The downside to Bluray is the cost. A Bluray player costs a minimum of £80, a good player costs £300. When compared to the inexpense of DVD players - the fact most homes own a DVD player - there is still a question mark over the future uptake rate of Bluray. Alongside the cost of buying a Bluray player, a good quality HD television is required to take full advantage of what Bluray has to offer. Finally you have the cost of the Bluray discs themselves. In the UK they have been at least £5 more than the DVD alternative; and in the US, $10 more.

While the current research is encouraging for Bluray, there is still a question mark over whether consumers will spend money to update their home entertainment systems to Bluray. The Bluray technology may need to bring it's costs down to become the dominant media format that DVD currently is.
