IBM has added Ustream to a long list of video technology company acquisitions in the recent past — like Clearleap acquired last month — buying the streaming video vendor for around $130 million (according to Fortune). The company had raised $50 million in venture funding, and was the sole video partner involved in the launch of IBM’s cloud marketplace in 2014. The typical analysis is that this rounds out a spectrum of technologies that now make IBM a player in corporate streaming video, particularly targeting customer contact and marketing activities. But I’m betting that IBM’s primary focus will be — although not be limited to — workforce communications. Marcia Conner makes my case in a tweet. .@IBM acquired video streamer @Ustream?
