We know most of you steered clear of retail zones that weekend but Black Friday was still big for HD, with NPD sales data revealing sales increases of 15 percent for HDTVs and 53 percent for Blu-ray players. No word on the average prices of Blu-ray players sold, but television prices have dropped so sharply (to an average price of $535) that revenues actually dropped 9 percent from last year. Regretting missing out on a particularly hot Black Friday deal? Your pain runs deep, share it with us.
