I want to know the answer to the following question:
Why did the CTRC send out a bulletin to broadcasters?
All the background I'm provided with is that "On December 16, 2010, some months after the CRTC issued a bulletin reminding broadcasters that analog transmitters had to be shut off by the deadline in mandatory markets, the CBC revised the documents accompanying its August 6, 2010 news release to state that it had the money for and is striving to transition all 27 transmitters by August 31, 2011.". Is that enough to answer the question?
