AT&T still operates 65,000 payphones in 13 states — more for the advertising they can stick on the sides than for the calls they generate. Even that won't sustain them much longer, the WSJ reports. AT&T said payphone revenue is small and declining, and it wants to get out of the business by the end of next year. The first coin-operated phone, installed in Hartford, Connecticut, went into operation in 1889, 13 years after Alexander Graham Bell invented the device. The payphone killer isn't the iPhone alone, of course. The CTIA estimates that there are 251 million wireless customers in the U.S. — or 84 percent of the population. (Photo by Mayr)
