As pointed out in the notes the Angry Birds entry is a bit of a non sequitur since that's more like measuring how fast a given new TV show's viewership increased after TVs were already extremely common, and it's not exactly a world-changing technology like most of the other things on the list. It's not comparable to the other things, and was probably included for effect rather than its belonging on the list by shared criteria with the other items. I expect the others would look far less dramatic as a percentage—I'd guess the 12-year cell phone number and the 38-year radio number especially would move far closer together if percentages rather than an absolute count were used. TV/cell phone might well reverse, since they're already so close. The table sets off some serious "lying with numbers" warning bells.
