Last week we held the RADVISION Unified Communication Summit in Tel-Aviv. I was tasked with giving a key-note presentation on social media, and decided to look at it from an inter-personal communications perspective. These two concepts may seem very different, but my point was/is that they are set to meet, one way or another.

On one side you have the social media people, who are now regarded as cool and trendy. They tend to look down upon the "old" marketing tactics (from the '90s, that is), and they talk about how Facebook, Twitter, YouTube and the likes can help your company make millions with hardly any need for investment.

Demand for upstream bandwidth is growing. Floyd Wagoner, a director of marketing and communications for Motorola Access Networks Solutions, said in an interview today that a U.S. cable provider has seen peak upstream bandwidth use increase by 24 percent from 2007 to 2008.

Andy Abramson stated recently, once again, that video conferencing will take off in 2009:

I've been saying that IP based video conferencing will be taking off in 2009 and it looks like I'm right with that prediction.

NASA and Verizon have reworked their agreements and now will have IP based video and web conferencing supplied by the Baby Bell.

I must say that I believe Andy is correct. It was not that apparent at CES that video is happening, but it was there - in the fringes.

They call it talking heads for a reason.
