Pagers
Pager, a dedicated radio frequency device, that allows the pager users to receive messages broadcast on a specific frequency over a special network of radio base stations was developed by Al Gross and was use by the Detroit Police Department in the1921. But, it was not until 1949, that the very first telephone pager was patented. The name pager was first used in 1959, when Motorola made a personal radio communications product called pager. By 1994, there were over 22 million pager users worldwide. The older one-way pagers are being replaced by more sophisticated messaging tools, like the two-way pagers. A 2008 study by the Pew Internet and American Life Project found that just 10 percent of the Americans used dial-up internet. The dial-up is slower than the available alternatives today, and is becoming extinct.
