I've been covering video conferencing (now often called "telepresence") products since the late 80s and saw my first offering in the mid-60s as a child at Disneyland. Over the years, product wave after product wave has come to market with the promise of the next big thing in telecommunications only to fail to meet even reasonable expectations for deployment in a market where users are measured in billions. Andy Grove, one of the smartest people I've ever met, referred to Intel's axed video conferencing effort as his biggest mistake while running that company.
