These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Adored by the Network: Current-season episodes (especially by latest airdate) will be aired until you've memorized them, while older episodes will air much less frequently. Similarly, they'll have mini-marathons of various currently-airing shows every day (compounding the previously described Adored Episode situation) while any concluded series that does not have On Deck or Wizards in the title is pretty much viewable only through DVD or Netflix purchase, and even so the former is aired only on late-night dead hours (unless it's Disney XD) and the latter is barely in a better position.
To put this into some perspective: Disney Channel made a promotion of a Gravity Falls marathon that aired Oct 20 2012 consisting of four episodes. The schedule for Oct 26 2012 listed six consecutive episodes of Good Luck Charlie - essentially an unannounced marathon that was an hour longer than the promoted Gravity Falls "marathon." And this doesn't count episodes of Good Luck Charlie that aired still later the same day, non-consecutively. The daily schedule on Disney Channel typically resembles something like this with various other shows.
Friendly Fandoms: Both Austin & Ally and A.N.T. Farm are this to iCarly, despite being on rival networks, have a friendship based around the supporters of the three major canon relationships on the shows, Carly/Freddie, Austin/Ally, and Chyna/Fletcher, Three of them being examples of the Just Friends.
Hollywood Hype Machine: One of the most well known examples. As well as being on these shows, the actors also usually release an album and have a finale movie. Unfortunately, it rarely leads to lasting success outside of Disney (though that seems to be changing now, at least with Selena Gomez and Demi Lovato).
There's also a significant (typically male) older audience as well, ranging from late teens to well over typical college-age. Given what appeals to males in the first place, this can lead to some Unfortunate Implications.
Screwed by the Network: I'm in the Band was abruptly canceled after one season, for unexplained reasons, all the while apparently being the highest-rated live action show on Disney XD.
