DVD distributor Netflix and Best Buy, the big U.S. electronics retailer, have thrown their support behind Sony's Blu-ray high definition DVD format. The support of the two major retailers for Blu-ray effectively means the end of the format war with Toshiba's HD DVD. It follows a decision by Warner Bros to switch to Blu-ray. Netflix will wind down its HD DVD stock and Best Buy said they would now actively promote Blue-ray. The No. 1 CE retailer Wal-mart has not announced its position on the two technologies. Many analysts believe there will be a sharp uptake of next generation DVD players once the format issue is settled. Netflix is also teaming with LG to build a video on demand set top box. Report
