I want to know the answer to the following question:
When did the CBC announce service would be discontinued to analogue transmitters?
All the background I'm provided with is that "CBC announced on April 4, 2012, that it will shut down all of its approximately 620 analogue television transmitters on July 31, 2012 with no plans to install digital transmitters in their place, thus reducing the total number of the corporation's television transmitters across the country down to 27.". Is that enough to answer the question?
Answer: yes
