This sounds like subliminal advertising
The United States does not have a specific federal or state law addressing the use of subliminal messages in advertising. Instead, it is the country's advertising and broadcasting regulatory agencies that deal with the topic and its impact on the public. In contrast, other countries do have specific laws in place concerning subliminal marketing.
Britain and Australia, for example, ban subliminal advertising for any reason. there have been alleged messages hidden in music, for example the rock band Judas Priest were sued after two teenagers listened to a song titled "Better by You, Better than me" which contained a sublimnal mseeage of "Do IT" which althouguh seemed innocent within itself, was argued that the two boys, who were believed to be suicidal already, caused them to take their own lives.
"The judge, Justice Jerry Carr Whitehead, ruled that the First Amendment's protection of freedom of speech and press does not extend as far as subliminal messages. Since the recipient of a subliminal message is unaware of it, the message can't contribute to dialogue, the pursuit of truth, the marketplace of ideas, or personal autonomy. There is no information exchange when it comes to subliminal messages, and no disagreement or argument is possible if recipients are unaware of the message's presence. Judge Whitehead also explained that people have a right to be free from unwanted speech. Since subliminal material cannot be avoided, it constitutes an invasion of privacy (Vance v. Judas Priest 1989b)."
"Justice Whitehead ruled, however, in favor of Judas Priest. His ruling was based on the defense's insistence that the power of such a message to move a person to action has never been proven (for more on this idea, look at the psychology section of this website). He stated his conclusions on the subliminal threat in this way: "The scientific research presented does not establish that subliminal stimuli, even if perceived, may precipitate conduct of this magnitude...The strongest evidence presented at the trial showed no behavioral effects other than anxiety, distress or tension." (Vance v. Judas Priest, 1990)"
The problem with this sort of advertising is that although there is proof that it can have an effect it is not always broadly effective, then there is the the fact that even the best best marketing companies cannot predict mob mentality, the Vuvuzela was not an expected thing at the osuth african world cup and it became huge, but it then went the other way and people heard it so much that they started hating it.
So in conclusion, it is possible that it could work, however if it were broadcast in certain countries it would be illiegal and other countries may not be as effective as they'd hoped. join that with the fact many companies wouldn't want to get caught doing so as it would appear unethical practice, so it is unlikely that it would ever happen
