AT&T actually owned all the telephones on their network (which was effectively all the telephones in the United States). If you wanted to use a telephone that wasn't made by an AT&T subsidiary, you had to transfer ownership of that phone to AT&T before they would allow it on their network. A significant legal precedent from the 1950s (Hush-A-Phone) relates to AT&T threatening to cut service to customers who dared to install a metal cup on their telephone receiver to muffle the sound of their conversation. |
