A couple of others that haven't been mentioned:
The fish locker- Mainly sea fishing based, so might not be for everyone. But the guy seems really genuine, owns a boat, and puts up lots of really interesting diving/nature/catch and cook videos. Well worth a watch.
John Arthur fishing- Match fishing does very little for me, but there is something about watching someone what is excellent at what he does. Fascinating to see how someone who is at the top of there game in the match fishing world, approaches a variety of venues.
Cadence TV- One of the few tackle channels that's worth watching. They have the perfect balance between promoting there kit, and giving great advice. James Robbins is very informative, loads of great videos, I really felt his stick/waggler videos helped me considerably when I started to fish the float on the Severn.
John Care- I think he might post on here. Only posted a few videos, but all worth a watch. Took a huge amount of information/rig advice from these videos when I had just started to fish the river.
Saltwater Angler- I enjoy Bass fishing, and I enjoy his videos.
