Why did disney get rid of all the good shows.?

i remember shows like the little mermaid, the adventures of winne the pooh, ducktales, outta the box, chip and dale rescue rangers, house of mouse, recess, and lots more. i know that you cant keep the old shows forever but you dont need to ruin characters with the learning stuff why. i mean look a pooh bear. what the heck happened to christopher robin in the super sluth pooh bear. instead we get someone named darby and a knock off of dora the explorer. and mickey is just a variation on it. disney seems to have lost all its adventure in shows. the outta the box was a fun way for children to learn yet it was like an adventure. why doesnt disney bring something thats not all about learning. i mean the old shows you leearned stuff through the lessons that the characters learned from there adventure in that episode. so why does disney give us this learning cr*p for then?
