One month after shattering records with Raising the Mammoth, Discovery Channel's Walking with Dinosaurs reigned supreme in April 2000 as the programming event earned an 8.0 household rating in the U.S., nabbed six Primetime Emmy nominations and was named Oustanding Animated Program. The three-hour special covered 155 million years of prehistory using animation and animatronics to recreate the sights and sounds of dinosaurs walking the earth.
