Online retail sales in the U.S. increased year-on-year in the second quarter, which continues a quarterly growth trend that began in last year's fourth quarter and merits guarded optimism for the second half of 2010, comScore said on Tuesday.
U.S. e-tail sales reached US$32.9 billion, up 9 percent compared with 2009's second quarter. The year-on-year growth in this year's first quarter and last year's fourth quarter was 10 percent and 3 percent respectively.
Prior to this string of three growth quarters, sales fell year-on-year in 2009's second and third quarters, were flat in 2009's first quarter and fell in 2008's fourth quarter.
ComScore is at this point "cautiously optimistic" about the rest of 2010, which includes the end-of-year holiday shopping season, a crucial period for U.S. retailers.
Factors that could derail the upswing include a rise in unemployment and stock market uncertainty, comScore said in a statement.
Some products that enjoyed brisk online sales in the second quarter included consumer electronics, computer software, computers, peripherals, PDAs, books and magazines.
