Fun Facts about Conference Calls
Although they may seem as a modern contraption, in fact, conference calls were developed by Bell Labs in 1956!
This was the era of room-sized computers and of course no Internet. In 1964 at the New York World’s Fair, American Telephone and Telegraph – you may know it as AT&T – introduced the Picture phone, an invention that invited the visitors to talk to persons thousands of miles away at Disneyland in California. It was revolutionary since it included a small screen connected to the phone sending visual and audio information on three phone lines simultaneously to be able to handle the bandwidth, a small black-and-white picture was sent every two seconds.
