5 Companies That Came To Win This Week


Samsung Set To Challenge Google Android With Tizen OS

Samsung this week said it would begin selling smartphones running its own Tizen operating system by the end of the second quarter. The gutsy move is a direct challenge to Google's Android mobile operating system that dominates the smartphone market.

Partners cheered the move, saying it could drive more innovation in the smartphone arena. In addition to freeing Samsung from rules and restrictions that surround Android and its product release cycle, Samsung will be able to more tightly integrate its own OS with its smartphone hardware. That should put the company in more control of its own destiny.
