The second host of "Zoorama" was Bob Dale, who would go on to become a very familiar face in San Diego. He interviewed curators and keepers about the natural history and care of exotic animals at the Zoo, introducing them to the public. Dale also said that even when Dr. Charlie Schroeder wasn’t physically there during filming, he felt his presence—"It was like he was watching right over my shoulder"—and made sure that the show followed Dr. Schroeder’s criteria. For many years, "Zoorama" was the Zoo’s greatest ambassador, introducing millions of people around the world to the San Diego Zoo and showing them sights they couldn’t see elsewhere. It became the longest-running program in San Diego history, both a national and international success. "Zoorama" was even given a national slot on the CBS network for one year—the first time for a locally produced program. By then, it was being seen by 16 million viewers each week.
