If the basic concept of Matt Houston seemed so familiar when the series launched in 1982, well, look no further than the guy who was the show's producer---Aaron Spelling.
Series creator Lawrence Gordon came up with the idea of Houston, a Texas oil magnate, spending his free time in LA as a private eye. Basically, Houston (Lee Horsley) was the diametric opposite of another famous Texas oil magnate in prime time----J. R. Ewing (Larry Hagman, Dallas). Houston spent his money to finance his cases, mostly helping friends in distress. But the point I was trying to get to was that, aside from the oil, Houston was a civilian version of Frank Gilroy's millionaire cop, Amos Burke, and Spelling was a producer on Gene Barry's seminal crime drama, Burke's Law.
Helping Houston along was lawyer C. J. Parsons (Pamela Hensley, ex-Buck Rogers in the 25th Century), who not only dispensed legal advice, but also some tender loving care, and more than once ended up a damsel in distress.
However, not all was well. The supporting cast was overhauled after the first season, with only Hensley returning, aside from Horsley. Paul Brinegar (ex-Rawhide) played a ranch hand, his first TV gig in years. In the 3rd season, TV legend Buddy Ebsen, a few years removed from Barnaby Jones, joined the show as Houston's uncle. That mirrors Universal's decision to bring in Fred Astaire to back up Robert Wagner on It Takes a Thief. The end result was the same. Matt Houston was cancelled after 3 seasons.
Here's the open:
Horsley would follow up with Paradise, which was rechristened Guns of Paradise in its 2nd season, then teamed with 70's icon Lynda Carter in Hawkeye, a one year wonder for producer Stephen Cannell.
