ENIAC Facts

 In February 1946, the first ever general purpose digital electronic computer was dedicated at the University of Pennsylvania.  The machine was called the ENIAC (Electronic Numerical Integrator and Computer).  It cost over $500,000 ($6 million today), weighed about 57,000 pounds and took up 1800 square feet.  It had 17,468 vacuum tubes, 70,000 resistors, 7,200 diodes, 10,000 capacitors, and 5 million hand soldered joints. It used enough electricity to power 114 homes. The longest time between vacuum tube failures was 4 days and 20

The first task it was to perform calculations pertaining to the development of the hydrogen bomb. It stayed in service for nine years.

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.
