subliminal message is a covert content, one hidden visual or auditory message that acts on the subconscious of the person who is exposed to the message in question.
These are implicit messages that have some predefined purpose and are usually used as an fsubtle way to encourage some kind of behavior, be it the purchase of a product or an attitude within the scope of ethics and morals.
In many cases, this type of message is an image that is hidden in a video and that is imperceptible (or almost) to the person. Often, these contents can be inserted in just one frame of the video. Several brands have already been indicated as users of subliminal messages in their marketing strategy.
In the musical context, several people claim that there are subliminal messages in songs, with sentences that are uttered almost inaudibly. There are also cases where obscure messages can be heard when the music is played backwards.
One of the main examples of this type of messages is found in cartoon, and some people claim that these messages are introduced with the aim of influencing children to take action.
