This article at newsarama.com doesn't sound too hopeful for the future of Krypto on Cartoon Network. I have no idea how accurate this is, but I thought krypto fans would want to see it.
I have no idea if the letter writing campaign suggested in the article would work but it probably wouldn't hurt.
Inside Source Alleges Licensing Dictating Why DC Titles Being Dropped At Cartoon Network
by Steve Fritz
Fans wondering why Cartoon Network dropped Teen Titans and Justice League Unlimited may finally start getting their answers. As it stands, a very well-placed source inside Warner Bros. Animation informed me that the last currently-running DC-related property, Krypto The Super Dog, is also on the verge of being cancelled.
"CN wants to focus on their own properties," says the source. "While I can understand this, I think that Krypto needs saving. I know it's not necessarily the most popular show on CN, but, it is a WB Animation/DC property, and so saving it could have very positive repercussions on the long-term DC/CN relationship. We weren't able to save JLU or Teen Titans because we didn't know that they were ending until too late. But if we act now to start a 'Save Krypto' letter writing campaign to the powers that be at CN, it might make a huge difference in the future of the show. Plus it shows CN there is a large fan base for the DC properties on their network, possibly paving the way for a return to CN of several other DC properties"
From what I've been told by my source at Warner Bros. Animation, the ratings on Krypto are such that it's currently on the bubble. The person felt a good letter-writing campaign might be just enough to give the show a green light for another season.
If fans want to do this, or just plain vent at CN about the removal of all DC-related shows from the schedule, the best way to do that is to write an actual letter and send it to the following address:
Save Krypto c/o Programming Cartoon Network 1050 Techwood Dr. NW Atlanta, GA 30318.
