Arizona’s economy is said to be built on The Five Cs: Cattle, Citrus, Climate, Copper, and Cotton.

But things have changed. Today, it’s aerospace, biotech, and tourism that drive the state’s economy.

The Five Cs: A Century Later is a half-hour radio documentary that examines the state’s original economic engines. We explore their past and hear predictions about their future.

The Five Cs aired in 2012 on Tucson’s NPR station, KUAZ-FM. It received a regional Edward R. Murrow Award for “Best Radio Documentary” in 2013.
