Sorenson VP-100
AT&T demonstrated its first Picturephone at the 1964 World's Fair, and started selling the $1,000 gadget in 1970. Users weren't prepared to pay the $90 a month fee. But after Video Relay Services for the deaf arrived in the 1990s, the videophone concept finally took off. In 2000, Salt Lake City-based Sorenson introduced the VP-100 videophone, backed by FCC subsidies and free to deaf users, which plugs into any TV. This year, a small business called Viable - run by deaf employees - launched its own rival product.
