According to the WSJ, Google is the process of designing its own internal instant messaging system, similar to RIM’s BBM. Earlier this week Apple unveiled iMessage- it’s version of BBM. As of now Google has Google Talk based off Jabber IM protocol which doesn’t provide a delivery or read confirmation, and requires a steady data connection to remain logged in. Will RIM put up a legal fight the way it did with Kik? Or will RIM answer back by further innovating BBM?
