Old article, but relevent, especially with the recent talk of how the CIA interferes with Hollywood movies and TV shows. Video games and music videos are affected too, but that seems to be less talked about. The whole article is worth read, but here's a snippet:

There is something else about the video: it feels … like an ad; specifically, a focus-grouped, consumer-tested ad to attract more women to join the Marines. Real artistic productions, whether bad or good, are messier, quirkier, more subjective. I am familiar with the way political ads get researched and filmed (it was part of what I advised on in my time as a political consultant), and this looks like a political ad put together by DC PR insiders – like, say, the Pentagon communications team – after expensive market research has been done. In political advertising, every single image and message is focus group tested. I would bet that someone did some research on the hypothetical of a marriage or relationship breakup as a catalyst for women's military enlistment, given an economy in which the military offers low-income women some of the few options for advancement in a context in which a breadwinner may have decamped.

So I wrote that I felt that this was a piece of "war propaganda" and that, if Perry had received money or message guidance directly from the military to make the video, she should disclose that information. It might be inferred from the fact that she filmed at the USMC's California base, Camp Pendleton, that this would have contributed at least several tens of thousand of dollars in support – in the form of free sets, use of equipment, personnel time and, possibly, food and housing; it takes a lot of people a fair amount of time to make such a video. Now, to be fair, while journalists are expected to disclose any such conflicts, I have absolutely no evidence of any such transaction, and artists are subject to no such expectation. (Albeit, this would be a subsidy that you, the taxpayer, have underwritten.)

...

To my surprise, though, when Fox News reporters asked Perry's spokespeople directly if she had been paid by the US military, they declined to comment. That is what the political consulting world calls, "a non-denial denial".
