WASHINGTON -- Global sales of tablet computers surged 50.6% last year, with Apple (IW 500/4) clinging to the top vendor spot amid strong gains by rivals, a survey showed Wednesday.
International Data Corp. (IDC) said worldwide tablet shipments totaled 217.1 million, up from 144.2 million in 2012.
IDC said Apple's iPad is increasing sales but slower than the overall market, and that growth rates are tapering off in the big markets like the United States.
"It's becoming increasingly clear that markets such as the U.S. are reaching high levels of consumer saturation and while emerging markets continue to show strong growth this has not been enough to sustain the dramatic worldwide growth rates of years past," said IDC analyst Tom Mainelli.
"We expect commercial purchases of tablets to continue to accelerate in mature markets, but softness in the consumer segment -- brought about by high penetration rates and increased competition for the consumer dollar -- point to a more challenging environment for tablets in 2014 and beyond."
IDC said sales in the fourth quarter grew 62.4% from the third quarter to 76.9 million, amid a holiday season featuring several new product launches. That was up 28.4% from the same period a year earlier.
In the quarter, Apple sold 26 million iPads, for a 33.8% market share. That was down from 38.2% a year earlier.
"While the quarter represented (Apple's) most successful on record, its year-over-year growth of 13.5% was well below the industry average," IDC said.
"The numbers bring into focus the challenges the company faces as it attempts to grow its tablet business in markets outside of its traditional mature-market strongholds and in the face of continued success from competitors both large and small."
Samsung (IW 1000/14) was the number two vendor, selling 14.5 million tablets for an 18.8% market share, according to the survey.
IDC said Amazon -- which does not publicly reveal sales of its Kindle devices -- sold 5.8 million tablets in the fourth quarter, securing the number three spot globally with a 7.6% market share.
