Face-to-face meetings can be expensive to get all of the people together. Video conferencing can be a very useful and inexpensive way of having meetings.
How is it working out? http://www.itbusiness.ca/blog/where-have-all-the-people-gone-they-must-have-gone-on-mute/56769 relates how it appears to have taken a twist.
“However, the novelty of digital face-to-face discussions seems to have worn off as participants started turning off their video cameras and began engaging in the discussion only through the audio feature. Most importantly, they remained as part of the discussion with the mute button turned on! And thus enabling them to multitask while, in parallel, shuffling paper and replying to emails.”
The telephone has been reinvented.
