I really enjoy reading this blog. This post gives a 360 overview of the mobile industry worldwide and shows you how huge of an industry mobile actually is.
'Lets start with comparisons. Newspapers? the total circulation of all daily newspapers worldwide is about 480 milllion. Cars? There are about 800 million cars on the planet. Cable and satellite TV subscriptions? About 850 million. Personal computers including desktops, laptops and netbooks, about 1 billion. Fixed landline telephone connections, about 1.2 billion. eMail users about 1.3 billion. Internet users about 1.4 billion. Television sets about 1.5 billion. And credit cards? About 1.7 billion people carry at least one credit card in their wallet.
But there are 4 billion mobile phone subscriptions now in January 2009. More than twice the number of credit card owners, 2.5 times the number of TV sets or internet uses, approx 3 times the number of email users of total landline phones and yes, four times the number of personal computers. This is a monster sized industry, totally towering over all others.'
I really recommend reading this post.
