There is only one positive change I can mention about the Disney Channel. The positive change is in the way the Disney Channel at least attempts to appeal to a more diverse audience, both ethnically and econimically. By not having people pay so much for it, viewers from a wider economic class range can watch the Disney Channel. By having shows featuring families from a wider variety of ethnic backgrounds, the Disney Channel appeals to viewers from a larger range of ethnic backgrounds. I guess appealing to a wider range of viewership is the one and only positive change the Disney Channel has made in the past 15 years or so.
