For better (https://tvtropes.org/pmwiki/pmwiki.php/Main/GrowingWithTheAudience) or for worse (https://tvtropes.org/pmwiki/pmwiki.php/Main/WereStillRelevantDammit)? Are there any shows that have done a reasonably decent job with staying true to the type of show that made if popular in the first place in the face of a cultural shif? For example, Sesame Street (https://en.wikipedia.org/wiki/History_of_Sesame_Street) has been noted to have always been based on social science research. In effect, they'll try to give their intended audience what they want depending on new studies coming up and suggesting something new has to happen.

On the other hand, you have a show that in hindsight, has few dated references (https://tvtropes.org/pmwiki/pmwiki.php/Main/UnintentionalPeriodPiece) to things that were relevant at the time. More explicitly, you have something like Happy Days (https://scharplingandwurster.com/a-history-of-happy-days-anachronisms/), which admittedly and quite frankly, went from actively trying to look like an authentic 1950s period piece to just paying "lip service" (https://tvtropes.org/pmwiki/pmwiki.php/AnachronismStew/LiveActionTV) to that idea and otherwise being a contemporary (https://www.sitcomsonline.com/boards/showthread.php?t=34597&page=2) sitcom.

In the opposite direction, are there any shows (https://www.reddit.com/r/television/comments/4uj07n/tv_shows_that_arent_afraid_of_disrupting_the/) that stubbornly (https://en.wikipedia.org/wiki/Reset_button_technique) stuck to their respective program's status quo (https://tvtropes.org/pmwiki/pmwiki.php/StatusQuoIsGod/LiveActionTV)? In other words, they stayed forever a constant in times of change.
