In September, we wrote about 10 businesses facing extinction in 10 years. Our list included businesses like record stores, newspapers and used bookstores. But one of the items on our list took one step closer to extinction this week: pay phones. According to this Wall Street Journal article (subscription required) AT&T has decided to shut down its 65,000 pay phones throughout 2008. Verizon Communications Inc., however, has decided to stay on the streets with its pay phone booths, specifically those located in the Northeast in busy spots like New York and Boston. What product can phone booths thank for their demise? Cell phones, of course. By late 2007, there were almost 251 million wireless customers nationwide among a U.S. population of 301 million, the CTIA industry trade group estimates.
