Worldwide tablet shipments recorded a year-over-year decline for the first time since the market's inception in 2010, according to preliminary data from IDC. Overall shipments for tablets and 2-in-1 devices declined by 3.2 per cent year on year to 76.1 million units in the fourth quarter of 2014. However, shipments for the full year of 2014 increased 4.4 per cent, totalling 229.6 million units. IDC noted that the market is still very reliant on Apple and Samsung sales. Apple's lead over other vendors has yet to be truly challenged as it shipped 21.4 million tablets in the quarter, accounting for over a quarter of the market with a 28.1 per cent volume share. Samsung managed to hold on to second place with 11 million units shipped. Release
