I too would like to see more shows based on instruction and less on "buy lure X". Back in the day when I was trying to learn how to hunt Spring Gobblers there were few vidoes available. The ones that were were all about call in and shoot, much like the throw and catch fishing shows today. I found a guy named Denny Gulvas that did videos where he called in the birds, but didn't kill them. He explained what he did and why, what to look for and how to adjust your calling to the gobbler's mood. Taught me a ton and made be a better hunter.
Wish there was a fishing show that did the same. Explain how to read your fish finder, not only the $3000 ones but ones like the Hummingird 150 & 170 that so many guys use. What rod weight/action to use for different lures and why. How to rig different baits and how/when to use them. How to select line, the properties of each and why this one is better for this situation. When to fish a type of lure and why. How to select colors for different situations and why.
In other words, try to teach the viewer how to be a better fisherman and not just a "look at me catch fish" type of show.
Recently I've found a show called Lost Lake where they do some of this. Put a guy on a lake, let him figure it out, and explain what he did and why.
