THIS WEEK ON 
SCIENCE FRIDAY...

Fifty years ago this month, the U.S. Army and the University of Pennsylvania teamed up to produce an all-electronic machine that heralded the beginning of the Information Age. In this hour of Science Friday, we'll look back on the half-century since ENIAC was invented and reflect on how computers have revolutionized our lives.
