Market researcher Gartner has released its newest estimates on the tablet market last year, with units approaching 200 million. So who were the biggest winners and losers in this space in 2013? While all of the big players in this space were technically winners, as the tablet market grew by nearly 70% year over year, there were some major and noteworthy shifts in market share.

In this video from Tuesday's Tech Teardown, host Erin Kennedy and Motley Fool tech and telecom bureau chief Evan Niu take a look at the newest tablet market share numbers, to see where all the major names landed this year. The most major shift was Apple's (NASDAQ:AAPL) share falling from over 50% to around 36% percent, with Android-powered tablets rising to 62% of the market share. Microsoft's (NASDAQ:MSFT) Windows tablets have also begun to gain a small but significant foothold, while Samsung continues to gain ground on Apple in this space.
