Not exactly. BBC was intended as a journalistic source and not more than that.
Voice of America was created to spread the American viewpoint into other parts of the world
(propaganda, if you will).
That served a strategic purpose during the Cold War. But the primary goals of the two
institutions are rather different.
It's actually the opposite.
The VOA and its associated services like Radio Mart?* are intended to be impartial and are not intended to spread any "viewpoint" but, instead, facts.
The purpose of VOA news is to present factual, opinionated stories. When I did, twice, the annual reviews of Radio Marti, part of the job was to score "impartiality" and "clarity" of the news coverage.
