I'm looking for a word to describe an article published in a newspaper that's written by a shill. Basically a word that describes the article as blatant over the top praise without perspective. I know 'advertorial' might work but I'm looking for an adjective that describes a panegyric that isn't genuine.
Astroturfing is often used for the online version of this, maybe for paper newspapers as well. Astroturf is a brand of artificial grass, so this is an artificial grassroots article.
Astroturfing is the practice of masking the sponsors of a message (e.g. political, advertising, religious or public relations) to make it appear as though it originates from grassroots participant(s). Source: Wikipedia
Popular recently, and with a mildly humorous connotation (or at least origin), is "astroturfing." It's a play on "grassroots" - instead of getting actual sua sponte testimonials or support, you plant fake support. Wikipedia puts the origin back to 1985, but I first saw it in the IEEE Spectrum a couple of years ago. http://spectrum.ieee.org/geek-life/tools-toys/the-language-of-online-life
Paul Graham calls that kind of subtle PR article a submarine. I haven't heard that term used widely outside the tech-heavy crowd that reads his essays though.
