Is that really a "good" thing? USA innovated and created POTS, land line phones - and then again with wireless phones/radio phones that ultimately became cell phones. Emerging countries skipped all that, landline, pots, regulation of monopolies and ultimately in the end just were able to put in some towers and voila, cell phones all w/ imported technology that majority of people in that emerging country do not understand to the equilivent of magic. If there is no profit, it won't be built. Many countries didn't get cell phones until late 00's. Where now it's not really a cell phone, but "facebook."
