Alas, the march of time never stops. Only now it just got a little bit harder to tell exactly what time it actually is. Well, for some of us, anyway. That's because AT&T is finally putting out to pasture its so-called "POPCORN" time service, the automated system you could call any time of day to hear the robotic pre-recorded voice of a woman tell you the current time. It was called 'POP' because 7-6-7 (P-O-P) was one of a few prefixes that dialed the service, no matter what four numbers followed.
The system has been around since the 1930s, relying on manual drums of track recordings to determine and play back the current time. It was most often used to set your clocks by -- especially after power outages. But these days, with the clock displays on cell phones that are always correctly set (as long as the phone is connected), the need for such a service has declined. In fact, until now the service had been discontinued in every state except California and Nevada. As of September 19, even those old holdouts are calling it quits. POP is officially extinct. And in California alone, the freed up prefixes will create 300,000 new phone numbers.
So, RIP "At the Tone" lady. Perhaps you and the paper airline ticket system will become fast friends in tech heaven.
