Global tablet shipments are still on the rise, but are showing signs of "dramatic...significant slowing" as consumer markets such as the US become saturated, IDC said.
"It's becoming increasingly clear that markets such as the US are reaching high levels of consumer saturation and while emerging markets continue to show strong growth, this has not been able to sustain the dramatic worldwide growth rates of years past," said Tom Mainelli, an IDC analyst.
Recent trends "point to a more challenging environment for tablets in 2014 and beyond," he added.
IDC said there were 76.9 million tablets shipped in the fourth quarter of 2013, up 62 per cent over the third quarter but just 28 per cent higher than the fourth quarter of 2012. The rate of growth from the fourth quarter of 2011 to fourth quarter 2012 was actually 87 per cent, well ahead of the 28 per cent figure and the reason that Mainelli described a tablet market slowdown. "While the market's growth rates remain impressive, they're down dramatically," IDC said in a statement.
With so many tablet makers competing for the same dollars, the consumer tablet market will be soft, although purchases by schools and businesses will accelerate, IDC said.
Apple led in the fourth quarter, shipping a record 26 million tablets, up from 14.1 million in the third quarter and higher than the 22.9 million it sold in the last quarter of 2012. IDC noted that its year-over-year growth was "well below the industry average" and indicate the challenges Apple faces from many competitors and in markets outside of the U.S. and other developed countries.
Apple had 33.8 per cent of the tablet market in the fourth quarter, down from 38% a year earlier. Samsung was in second places, grabbing 18.8 per cent of the market, an increase from its 13 per cent share at the end of 2012. Amazon had 7.6 per cent of the market in the final quarter of 2013, Asus had 5.1 per cent and Lenovom 4.4 per cent.
Lenovo benefited from low-priced tablets sold in emerging markets. It has just 1.3 per cent of the tablet market in the last quarter of 2012.
