An example of this is in the industry is;
Synergy is present here as the film is being promoted at the same time as the song. They are working together to gain recognition in a quicker and bigger impact. They have got what you call a symbolic relationship. When watching the movie, you may recognize or possibly even notice the song for the first time but because its at such an iconic moment of the film the songs becomes iconic to. so the film may influence you to go out and buy/download the song. However, it works the other way round also. When hearing the song, and watching this music video, could inspire your want to go watch the film after seeing clips from the film in the video whilst listening to the well known song from that film. Its advertising both forms of media by synergysing together.
Another form of synergy that you see in music videos is where two well know established artists collaborate and are seen together in the music video. An example of this is;
By having two well known artists collaborate on one song and appear in the video together, this can create a bigger fan base for both of them. Fans from either artist may not necessarily have liked the opposing artist before or know much about them,but by being introduced to them through an artist they are already a fan of, can lead them to becoming a fan of theirs. For example, a fan of Rihannahs may not particularity like Nicki Minaj, but because she has listened to their song because she's a fan of Rihannahs a opinions and views might have changed about Nicki. They are advertising each other of each others backs.
