Most of the time, a subliminal message will be used in the background of a song. It can even be used in TV adverts to make you more willing to buy the products. The brain will detect these messages even if you don't hear them consciously.
This could be done in advertising by giving you a subliminal message that you really feel like having a cheese sandwich. You will just go and make a cheese sandwich without knowing that an advertiser used this in order to get you to buy more cheese. This is taking it to the extremes, but this is kind of how it works.
Subliminal messages are quite intrusive because people will not receive the message properly. Being taken in by the brain when in its unconscious state, you cannot place any reason or judgment around it. The information you receive can be taken the wrong way or jumbled with other messages.
To prevent subliminal messages from plaguing you, there are some things that you can do. One of them is to use your undivided attention at all times when watching TV or listening to songs on the radio.
The messages you receive can be eliminated or have little effect when you concentrate. The subliminal messages cannot be used in a dangerous way and most of the time advertising companies will use more direct messages. These can be heard consciously, but if you don't watch TV adverts and go into another room, you will still pick up these impulses. You might find that even listening to the radio in the background can give you subliminal messages.
