I loved those too. I'm an even bigger fan of '60s TV. I got the entire series of M*A*S*H on DVD, and loved Happy Days, but Mork and Mindy was such a huge downgrade compared to the Mork character starring in episodes of Happy Days--it wasn't the same fun. It was kinda, well, bland.
I love Laverne and Shirley (especially the Lenny and Squiggy segments), along with the Odd Couple, Green Acres (reminds me of the people around here!), as well as The Andy Griffith Show, Bewitched, the Munsters, Lassie (if you can even get that one--unobtainium both on physical as well as digital, this being the '50s series, not the movies) and many more. Since in the early 80's Nickelodeon had very little of their own content they often ran reruns of 50s and 60s shows when they had open time slots (later putting it into their Nick@Nite evening block), I was exposed far more to that era in TV than the 'modern' 80s era at the time, and the only exposure to 80's television were the Saturday morning cartoons like He-Man, Voltron, The Wuzzles and others.
I have always been fond of old things too, and being around my great grandparents a lot as a child made me more enamoured by the 1950s-60s style of culture, tech and life in general. That's why I'm like I am, and resistant to any form of 'future' I don't feel I belong in. I was probably the last generation that was taught how to take things apart, repair them and read schematics as I was growing up. Back then, at least until the mid-80s that was considered a vital childhood skill, and a benefit later in life.
Personally, I'd rather spend my off time re-aligning the IF transformers and tuners in my AM radios and enjoy the warmer sound of them over dealing with buffering, compression and other disadvantages of just pulling songs up on your phone. Radio is free, subscriptions to multiple services are not. Around here, there's plenty of great classic music stations on AM. Radio doesn't need internet, nor app updates, or accounts much less data gathering.
