I remember as a kid the old McDonalds signs where they'd say how many billions of hamburgers they've served. If you can find one of those old signs around today, it's likely to say one of two things: over 99 billion served, or billions and billions served.

When it comes to voice minutes on Skype, we can say the same thing. Skype has officially announced that over 100 billion minutes of voice calls have occurred using Skype over the past four and a half years. And unlike McDonalds, with signs that were never designed to handle more than 99 billion, Skype doesn't have to worry about changing any signs to indicate the billions of minutes served.

One does wonder, though, how many of those minutes were free versus Skype Out calls? Was it a billion? Less? More? Let me know what you think.

Edit: Skype PR has contacted me to let me know all 100 billion minutes are Skype-to-Skype. Skype Out minutes are counted separately.
