Nah, the mainstream media isn’t a woke propaganda machine! That’s just a conservative conspiracy theory.
Sure.
Subliminal advertising in movies and on TV began in the Fifties with things like this..
…being flashed before viewers’ eyes in fractions of a second. As a result, in 1958, the National Association of Broadcasters banned subliminal ads in 1958. The FTC views such ads as inherently deceptive and therefore illegal. If you look really closely at that screenshot, it says “Try racial justice” in faint grayscale letters.
Sharp-eyed Ann Althouse gets credit for finding this, which she posted and then, being Ann, ignored the real issues the stunt raises in order to go off track about the lyrics of “Try a Little Tenderness,” among other things.
Ooops, gotta run…I’ll have more to say in the comments…
Ethics Alarms 
This is one of the reasons I get frustrated with Althouse. It’s her blog, she can write about what she wants, but if your readers are constantly taking you to task for missing the point, maybe you should consider your audience? Some of the comments found there:It’s appropriate that it has “racial justice” in quotes, since there’s no such thing, anyway, but instead only justice and not-justice.
Don’t know what you were searching for but there is NO racial justice. There is just race.
If I’m wrong, please give me the definition of racial justice. What, if anything, has America’s First Half-Black president had to say about “racial justice”.
Justice doesn’t need modifiers, with the possible exception of “for all.”
Justice modified is not justice.
Yeah, I noticed that recurring thread through the comments as well. And if you believe (as I do) that there is but one race on this planet with variations based strictly on genetics, then the “racial” in “racial justice” is again completely unnecessary.
Who knew “Try a Little Tenderness” is a rape song. Weird.
Back when Snopes was focused on urban legends instead of politics, they did a post on the famous popcorn subliminal advertising experiment. Apparently it was all made up, and there’s no verifiable proof that too-fast-to-see messages actually work. https://www.snopes.com/fact-check/subliminal-advertising/
William Freidkin used nanosecond horrific images in “The Exorcist” to unnerve audiences.
Were audiences tested on a version of the film without the nanosecond imagery, and have the results been replicated?
Nah.
