Peter Parkes reports on the main blog that a new high had been reached in Skype usage: 15 million.

In other news: The BBC tech correspondent Rory Cellan-Jonesmade a Skype call from an airplane above Las Vegas sing Row 44 from a small aircraft during the International Consumer Electronics Show.

The reporter reached BBC on Skype with two firsts: "a live broadcast from a plane, and a video call."

But it wasn't perfect: "It was always going to be tricky to go live onto BBC World, and although we did manage to contact London, and they saw us for a minute, a software glitch then froze the picture."

But he sees Video on airplanes as inevitable:

"I hear you asking, do we really want to see the internet reach every corner of our lives? Isn't it a bonus to have somewhere that you can't be reached? Well, maybe, but I'm afraid it looks to me as if you won't have a choice - the internet is getting airborne, and for those of us addicted to connectivity that means one more place where we can obsessively check our email."
