Milton Caniff's adventure hero, Steve Canyon, made the transition to television in 1958, airing on NBC. It has only been within the last decade or so that the series was made available on DVD.
Canyon (Dean Fredericks) was a troubleshooter for the Air Force. Very little, however, carried over from the comic strip, which ran for nearly 40 years. The series was brought back in the spring of 1960 on ABC, and that was the last anyone would see of Steve Canyon until it was released on DVD.
For now, here's the intro, narrated by---who else?---Paul Frees. (Jackson Beck is otherwise the announcer at the start)
Update, 5/27/18: I finally got to watch the show, as it's been airing on Decades of late. Unfortunately, full episodes are not available on YouTube, just the above intro. What I saw was a tale that pre-dated the movie "Top Gun" by nearly three decades, as Canyon has to whip a group of playboy airmen into shape.
