JV, no offense intended but you really have no understanding whatsoever of how the TV industry works.
BDUs do NOT apply to the CRTC for permission to carry a service. The service (ie, the channel) applies for a broadcast license. The channel must then try to negotiate distribution with BDUs.
In recent years the BDUs have increased the cost for basic package charged to viewers considerably. That money did not go to pay for services (channels in the basic package). It went into BDUs coffers. So while you sympathize with the poor BDUs they are squeezing you for every dollar they can.
Did you ever ask yourself why you must purchase a whole package of channels when all you really want is one or two? They do the packaging for the most part. I really suggest you acquaint yourself with the industry.
Finally, BDU's want sports, movies,sex and ethnic channels because they make lots of mullah selling them to subscribers. They have no interest in helping a community no matter how beneficial a service may be. This is why they oppose any channel that is imposed onto them.
A Public Interest channel is not in the same category as an entertainment channel. The mission is not the same. That is why the CRTC protects and imposes services that are deemed to be in the Public Interest. Otherwise, if left to the distributors, these channels would never make it to Air.
On a final note, while you are so concerned about the poor BDUs, keep in mind that they benefit from a quasi-monopoly here in Canada. They enjoy the protection offered them by the CRTC and will fight tooth and nail to prevent American satellite services from ever becoming available in Canada.
