Go on, pick your jaw up off the floor -- this isn't that staggering, now is it? Considering all those cellphones that have been sold here recently, and the plethora of folks who just refuse to ditch that landline, four billion total phone lines seems just about right, truth be told. According to the International Telecommunications Union, our planet is now home to about "1.27 billion fixed lines and 2.68 billion mobile accounts," but the total number of people represented by these data is much less clear. Notably, the study found that "61-percent of the world's mobile subscribers are in developing countries," and further added that China and India were greatly to thank for reaching the milestone. And just think, there were less than 1 billion lines combined across the globe just 11 years ago.
