"Consolidation, rising value proposition of integrated conferencing, and the rise of combined synchronous/asynchronous collaboration all helped to spur tremendous gains for vendors in 2005, and the overall market continues to grow at a fast clip. Going forward, vendors should aggressively work to change customers' expectations about how they can use these products and focus on selling deeper into their customers, where two or three or even four other vendors' products might be hiding." - Robert P. Mahowald, IDC program director, Collaborative Computing.
