It may feel like everyone on the planet has a cellphone, but they don't.
A new report from the International Telecommunications Union found that at the end of 2011, 6 billion people had a cellphone subscription. That means 6 in 7 of us have a cellphone. It also means that 1 billion of us do not.
And when it comes to Internet access, the numbers are worse. According to the report, 2.3 billion have access to the Internet. That's less than half of the world's population.
The good news (or bad news, depending on your feelings toward global connectivity) is that the number of people with mobile phone subscriptions is growing rapidly. The ITU found double-digit growth in cellphone subscriptions in developing countries over the last year.
