Unified communications and collaboration is obviously meant for business. No consumer technology would adopt such a complex collection of syllables as its name. Regardless of where the concept for UC, or for UCC began, though, there is evidence that its the consumer market, rather than the enterprise market, that is driving innovation, and perhaps even leading the way for more mainstream acceptance and adoption of many UC technologies.
Tools like Skype, Google Voice, or Google Buzz are targeted primarily at consumers, yet provide some level of UC capabilities and become a sort of ‘gateway’ technology.
An article from TMCNet titled ‘VoIP, UC, and UCC: Still Driven by Consumer Tools?‘ notes “An argument might also be made that much of the value of UC or UCC actually is captured by use of relatively simple tools such as Skype, or Google Voice or any number of other rather easy to understand consumer applications.”
