The world population is just over 7 billion people, a number I can’t even begin to visualize. Last year the Telecommunication Union said there were just over 5 billion subscriptions worldwide by the end of 2010. This year they claim that at the end of 2011, there were just over 6 billion… Which means by the end of this year, there may be as many subscriptions as there are people on the planet. Does that mean everyone in the world will have a cell phone? Of course not, but the number is impressive nonetheless.
