The Earth & Sky radio series began broadcasting in 1991, on a few dozen radio stations scattered throughout the U.S.

Now, over three million people learn about sustaining a vibrant and healthy planet everyday at Earth & Sky. Our radio program is heard each day on more than 1,000 radio affiliates in the U.S., with an equally large audience overseas. In September 2006, we'll celebrate 15 years on the air and will produce the 5,000th science radio show. But if you heard our very first segment of Earth & Sky, it would have sounded like this:

"I'm Joel Block..."
"I'm Deborah Byrd..."
"...and this is Earth and Sky. "
