Technology History

Television was first introduced to the American public at the 1939 World's Fair. World War II delayed commercial network programming in the US until the late 1940's. A popular black-and-white model, the 1948 Admiral, had a 7 inch screen encased in a large metal box four times the screen size. It cost $2,495 ($22,642.49 at today's cost) 

One of the earliest computers, ENIAC was introduced in 1946. It weighed 30 tons, had 6000 switches, 18,000 tubes and occupied an entire room.

The Apple iPad has a  9.7 inch screen and weighs 1.3 pounds.
