I generally agree, but I think radio was heading in that direction whether they had live talent or not. Musical artists, talk show hosts, and anything else that’s on the radio have never been more accessible, so most people (especially my age) aren’t going to consume content via an outdated medium unless we’re driving. Even then, I usually listen to either a podcast or my Spotify playlist. People are already “going somewhere else.”
I think NBC’s 10pm proposal is a symptom of a bigger problem. Other than live sports, I can’t remember the last time when there was an original show on one of the major networks that I actually wanted to watch. “Abbott Elementary” and “Ghosts” are pretty good, but most shows are either safe, unfunny comedies (the “Night Court” reboot,) cheesy crime dramas (most of the CBS schedule), or game shows. There’s also outright garbage like “Farmer Wants a Wife,” which is better fit for meme material than something I’d actually want to watch as a full series.
