Counterpoint:
Media like broadcast TV and radio are so freaking expensive that everything used to be soundbites and headlines. You'd have panel shows where every panelist might get to have a couple of minutes of total talk time, and expect to convey all the necessary information in that time period. And now a
I'll concede some of that. I mean, back when there were three networks to watch (plus PBS) 60 Minutes was a Sunday night staple - certainly every Sunday at my house when I was a kid, and it was all 12 minute segments. On the other hand, you had PBS science shows, Cosmos, etc, that were an hour long and interesting for the whole hour, and I never was thinking "there's a ton of other stuff I could be doing in this hour".
I can't speak for others, but these days I tend towards the short videos, to the detriment of longer videos that are very interesting. As an example, last night I watched Tulsi Gabbard's speech at Turning Point. Super well done, but when I first saw it pop up on my feed, I was like, "20 minutes!?! Do I really want to watch that long?" I about had to force myself to set aside the lousy 20 minutes.
I've done the same with stuff like Jack Carr's Danger Close videos, which often run 1-2 hours. I'm pretty sure that 20 years ago, that wouldn't have bothered me, but now I keep thinking about the 20 five minute videos on 20 different subjects that I could be watching instead, even if they just give me a very incomplete view of a topic. Had I not forced myself to sit down for the entire videos (admittedly, often in two or three viewing sessions), I would have missed some really informative and interesting interviews.
I think Youtube Shorts makes this attention span thing ten times worse. Everybody wants to do these 30 second videos, often of total nonsense, for clicks and monetization. I probably could have watched quite a few hour long videos with superior content with all the time I've wasted clicking on worthless youtube shorts.
