So, In a short rundown, as most of you know, in 2007 the stoned idiots at Williams Street (a Studio in Atlanta producing material for Cartoon Network's Adult Swim Block) have the Aquateen Hunger Force movie coming out, and come up with a stupid plan to advertise it. "Let's put PCB/LED signs allover major cities," They said, "surely only good could come of this!" And they did it, and the devices looked like bombs and people freaked, and It hurt Cartoon Network, and Turner Networks Horribly. The Folks at Williams Street dodged any blame, and in the aftermath, Turner forced the 13 year head of Cartoon Network, Jim Samples (one of the people who ran the network from pretty much the beginning and made it what it was at the time.)

So, what happens if it doesn't happen, if there is no ad campaign? Bear in mind this created Cartoon Network's Lost years, as Stuart Snyder took over, and didn't know how to do anything well, killing Toonami on 2008/9/20 in the process.
Also, Scenario Two: It happens like OTL, but Turner all but torches Williams Street, and fires everyone in there, remotely related to the decision, completely dismantling the block, and replacing the staff with some of Sample's people. Maybe the Adult Swim block gets Shitcanned in it's entirely, and the Toonami is brought back to late night?
