I want to know the answer to the following question:
When did CBC discontinue its late-night broadcast of The National?
All the background I'm provided with is that "Until October 2006, CBC owned-and-operated stations aired a second broadcast of the program at 11:00 p.m.; this later broadcast included only the main news portion of the program, and excluded the analysis and documentary segment.". Is that enough to answer the question?
Answer: yes
