Menlo Park, CA–Pacific Media Associates (PMA) has reported that unit sales for rear-projection HDTVs grew by 23 percent for December 2005 compared with the prior month. Their service also shows that sales revenues increased slightly more, with a 24-percent rise. In spite of this end-of-year increase, rear-projection unit sales were down six percent compared with December 2004. During 2005, pressure from flat panel TVs kept down rear-projection sales. In December 2005, the $1,750 average street price for a 42-inch enhanced-definition plasma was about the same as for rear-projection models of similar size, and average prices for high-definition 42-inch plasma were approaching $2,000.
