(NEW YORK) -- Leading tech companies Apple, Nokia and Microsoft heat up the competition in the tablet marketplace with the release of new devices Tuesday. With increasing demand for tablets, the companies go up against other succesful gadgets already up for sale by Amazon and Google.
Apple is expected to announce upgraded versions of its iPad and iPad Mini devices, according to the New York Times, with new design and processors. On the same day, Microsoft is set to introduce new versions of its surface tablets, and Nokia will release a tablet in Abu Dhabi.
In 2012, about 120 million tablets were shipped, seven times the amount of tablets shipped in 2010, according to market research company Gartner.
While other companies try to gain a foothold in the tablet industry, Apple maintains its lead with 32 percent of the market. Samsung comes in second with 18 percent.
