More offensive (to me) than the scmaltzy ads cited above are several "news articles" I've encountered on what are claimed to be news sites. One link claimed to be to a story about a "new music teaching method" used in childrens classrooms but when you click the link all you get is a Buick ad that starts with a Buick sitting in front of "the school" (for about 4 seconds), and then the teachers go for a ride in the Buick. Teaching not mentioned.
There have been others similar, but I've never watched enough after the first Buick appears to remember what they claimed to be about.
