Every one of the major tech companies has taken steps to upgrade messaging. Microsoft has combined MSN Messenger with Skype, for example. Apple (NASDAQ:AAPL) has iMessage. Google (NASDAQ:GOOGL) has upgraded its efforts in a new platform called Hangouts. Start-up MessageMe may best them all anyway.

MessageMe has grown astoundingly in the two months since launch. According to TechCrunch, the service now has 5 million iOS and Android users while usage has tripled. And not just text messages -- MessageMe sets itself apart by allowing users to swap video, voice, and text messages as well as music, location data, and doodles, says Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova in the following video.

Users appear to appreciate the variety, and that's a problem for the incumbents. Google took years to upgrade its messaging system. Apple's Messages isn't much better. Don't be surprised if these two start a bidding war for the platform, especially if MessageMe offers a premium app that supports money transfers, Tim says.
