1974-80 NBC. James Garner. This is Jim Rockford. Tom Selleck appears twice as a private detective. Very funny. Dennis Dugan as Richie Brockelman, another private detective and a spin-off show, was also fun. There was another spin-off attempt and backdoor pilot with Lou Gossett and Isaac Hayes.
1982-87 NBC. Steele watching. I have the first season on DVD and still watch random episodes from the first few seasons pretty regularly. Even better I know many more of the movie references now, when I watched in the 80s I would have seen very few of those movies.
1985-89 ABC. I watched this when it aired. I have season one and two on DVD. I like the Herbert/Miss Dipesto episode where they are at the haunted house but the later seasons start to fall apart.
1977 NBC. Anthology series. Saw this mentioned yesterday in the comments in an old post in the Kinja archive. Not to be confused with Roald Dahl's Tales of the Unexpected, which was a British show. Quite a few of the other Quinn Martin shows are already here. One or two of these is on Youtube. 8 episodes.
1971-78 NBC.(Later ABC.) Peter Falk. Part of the NBC Mystery Movie originally. I've been watching a random Columbo lately, along with some 80s detective shows, and Dennis Dugan was on the one yesterday. I have the first four seasons on DVD.
1976-77 CBS. Norman Lear. Richard Crenna, Bernadette Peters, Michael Keaton. 24 episodes. When I find something new on Youtube I will always check the channel for more good things and found some of these episodes a few months old.
1970-71 ABC. Burt Reynolds. Cop. A Quinn Martin Production. Norman Fell. I saw some of this when we had get-TV. Some are on Youtube but I didn't check quality. 26 episodes.
1969-74 ABC. Anthology series. Decades has a Love, American Style all day marathon going. Bob Dishy was just on. Third time now I'm seen Bob Dishy since the Columbo episode I watched recently. Also in Barney Miller, Alice, back to back days, and now this. Proto Happy Days happened on that show too.
1967-75 NBC. Another annoying instance when searching Google only knows the remake. Have you people heard of Raymond Burr? Big star. Perry Mason. You should check him out. This show is one of my earliest TV memories. It must have been syndicated during the day. Jessica Walter was in a spin-off called Amy Prentiss on the NBC Mystery Movie that was covered here previously. Ironside was spoofed in the TV movie parody Murder Can Hurt You as Ironbottom, played by Victor Buono, and also covered here. After the fact while making this post I was able to locate the thumb drive that has some original Kinja TV posts on it and found the last promo collection here.
1992 CBS. Hanna-Barbera. John Ritter, Ed Asner, Tim Curry, Hector Elizondo, Jonathan Winters, Robert Guillaume, Buddy Hackett. I watched all of these last year. Good show. Comes and goes on Youtube. Part of several animated network shows meant to compete with The Simpsons that all tanked. 6 episodes. Three unaired.
1986-88 NBC. Michael Mann. Dennis Farina. This is another show that comes and goes on Youtube but the FilmRise channel looks like they have the whole thing up now in good quality. You can't watch just one because it is a serial. 44 episodes.
1994-95 NBC. Dabney Coleman. Craig Bierko. I watched one of these last year. NBC Blackout Thursday promo in the header. Wiki says it was one of the highest rated shows ever to get cancelled but it did have a Seinfeld lead-in. 16 episodes.
