Sony apparently has learned its lesson from the betamax battle and put virtually every effort possible in winning the High-Def battle with the HD DVD format.

Wal-Mart is the latest company to exclusively back the Blu-ray technology for high-definition DVDs.

The retail giant said Friday that it would phase out discs and hardware using the competing high-definition technology, known as HD-DVD. HD-DVD products will be off the shelves at Wal-Mart and Sam’s Club stores by June, the company said.

Earlier this week, Netflix announced it would carry Blu-ray discs exclusively and Best Buy will feature Blu-ray prominently over the HD discs.

This is good news for consumers who have been holding back to see which format would win the war before committing to purchasing a High Definition DVD player.  This should lead to an increase in sales and a decrease in equipment prices.
