> Today's Discovery Channel (and History Channel, and TLC, etc) - are vastly different than what they were when they started. All have definitely "dumbed down" to the LCD.
While with "educational" channels it.comes off as dumbing down, there's a broader effect of appealing to narrow groups that drive popularity and then moving on to appeal to the masses. Outside of TLC/Discovery/History you can see this in Food Network (where the cooking slowly migrated to the Cooking Channel -- typically on more expensive cable tiers) while Food Network was taken over by food tourism shows, advertorial series, and reality/competition shows; MTV, where the music keot migrating to subordinate channels while the main channel was taken over by non-music reality/competition programming, and lots of other outlets.
