Blu-ray sales alone should amount to at least three times what digital downloading is expected to bring in this year. In the first six months of the year, consumers spent $194 million on Blu-ray purchases, according to studio estimates -- a gain of nearly 350% from the $43 million that came from HD disc sales in the first six months of 2007, when growth was stymied by a format war between Blu-ray and rival HD DVD.
Unit sales of Blu-ray Discs in first-half 2008 were up 340% from the first six months of 2007, according to Nielsen VideoScan data. Nielsen numbers are based on point-of-sale data from most big retail chains with the notable exception of Wal-Mart and Sam's Club. Factoring in Blu-ray Disc sales at those two retail chains, studio estimates peg the number of Blu-ray Discs sold in the first six months of this year at 7.4 million units.
