* Sets estimate at 3 million units
* 2010 sales expected to double
SAN FRANCISCO, Oct 6 (Reuters) - Forrester Research on Tuesday raised its 2009 forecast for e-reader sales in the United States to 3 million units, underscoring the increasing popularity of the devices.
The industry tracker had previously estimated sales of 2 million units.
For 2010, U.S. sales are expected to double, bringing cumulative e-reader sales to 10 million by the year’s end, Forrester said in a report scheduled to be released on Wednesday.
“This holiday season, eReaders will be one category that’s a breakout success,” Forrester analyst Sarah Rotman Epps said in the report. “Lower prices, more content, better distribution, and lots of media hype are contributing to faster-than-expected adoption of eReader devices in 2009.”
Forrester predicts 900,000 units will sell during the holiday season.
Although new digital readers continue to enter the market, Forrester predicts device makers like Interead and iRex will account for only 5 percent of sales. (Reporting by Gabriel Madway; editing by Carol Bishopric)
