Whatever you think of this blog (and judging by the comments to Peter Barron's entry there are some of you in both the "like" and the "dislike" camps) it has never been our intention to use it solely for the purposes of advertising. Sure, we're happy to tell you about a new development if we think it's noteworthy, but we don't just run "house" adverts.
Well there's an exception to every rule. We at BBC World have been running some thought-provoking billboard adverts in New York City. They are a bit of a departure from anything we've done before, and we hope they get the message across to our new and growing audiences in the US that we are serious about reflecting all sides in our news coverage.
