I want to know the answer to the following question:
When was the 50th anniversary of BBC news broadcasts?
All the background I'm provided with is that "This event was marked by the release of a DVD, which showed highlights of the BBC's television coverage of significant events over the half-century, as well as changes in the format of the BBC television news; from the newsreel format of the first BBC Television News bulletins, to the 24-hour, worldwide news coverage available in 2004.". Is that enough to answer the question?
Answer: no
