I guess it depends on your definition of "New Channel". If the Cartoon Network changes its name to the "Adult Swim" channel and drops the kid stuff, does that make it a "new channel"? Not to me and most people who recognize programming changes. Wikipedia's entry is far from "official" too.
Was SpikeTV a new channel or a name change from TNN? Was SyFy a new channel or just a STUPID name change from SciFi?
It was never a "separate" channel. People can call it that if it makes them feel better about it.
Well, yes. We may not like it, but if Cartoon Network were to launch Adult Swim channel having its own channel number and its own position on a program guide with the same Adult Swim content 24/7, that does count as a new channel. A good example is Destination America channel. Granted, nearly 100% of its content had aired on other Discovery Networks channel and even the few shows that now premier there, they are soon aired on other Discovery Channel, but, like or not, Discovery America is a new channel. I suppose nearly all the channels on an MVPD line-up could be considered NOT a real distinct channel becasue so many of them air content previously aired on other servcies. The Hub is a good example of this, but is or even the old "N" when it went from a block of programming on Nickelodeon to its own CHANNEL 24/7, and back then we referred to it as a new CHANNEL. After all, if we were to take the opposing logic that new channel mean new content or content having not been aired by any other channels or as blocks on other channels, all MVPD's channel count would have to be greatly reduced to maybe 20, not the hundreds.
But even more simple: when one inquires about the number of channels a service provides, is it not the common opinion that if a service has its own distinct channel number and position on the guide, that counts as a CHANNEL? Most would say YES, but with a great big BUT about common content across a media company's "channels," but still a separate CHANNEL.
So, are you saying the following Wikipedia statement is false and there was no such announcement nor action: "It was announced on March 27, 2013 that FXM would go from being a programming block on Fox Movie Channel to being a full scale network of the FX Networks family, which also includes FX and FXX."
If so, it would be great if you would edit that Wikipedia page with the correct information you have. That's how Wiki's work. Intelligent, knowledgeable folk like yourself having access to keeping things correct and up to date, reflecting the latest changes . I will re-visit that page and look forward to your elucidating us all.
