There's almost too much volume these days. There's dedicated websites/apps/podcasts for Apple, Android, PC gaming, Xbox gaming, PS4 gaming, Switch gaming, etc. Product Hunt was a hot thing for a while and is still running. In terms of more general coverage, The Verge, Engadget, Lifehacker, Wired, and NYT Wirecutter are still good among many many others.
There was a good run of Computer Chronicles, TechTV, and G4 for a while there. These days, This Week in Tech still exists in podcast form. G4 had a short revival as G4TV a few years back. There's nothing nearly as popular these days, but there's still lots of good ones like Waveform, SomeGadgetGuy, and AwesomeCast.
There is very little with a) high technical quality in the presented content, b) an assumption that the average viewer is reasonably intelligent, and c) high production quality.
The Computer Chronicles was kind of unique that way.
Edit: OTOH I just saw a 55 minute well-produced youtube video on ASML's EUV photolithography machine that fulfilled all of that. I had some bias against this channel for some reason I don't remember, but anyway: https://www.youtube.com/watch?v=MiUHjLxm3V0.
Veritassium is in a league of its own. Just take a look at their last year's videos. The production value is just second to none.
They have enough of a following now that they can dedicate 55 minutes to something and not worry about the algorithm, which usually dictates much shorter form factors
This was the first of their videos that impressed me. Looking back, I have watched a few of their videos per year. Previous were videos tended have much less content density and quality.
I really enjoyed the segments where they let ASML's (now former) CTO Martin van den Brink just talk.
