Target Audience Research: How do media industries target those audiences?

For Muse, media industries tend to target their audience by making all their music videos very contrasting from each other for example Hysteria doesn't feature the band in it at all it is just one whole narrative which reflects the lyrics
So for Hysteria they try to engage their audience by featuring a narrative throughout the whole video but one that reflects the lyrics so that the audience can try to relate to the video and song. The way they contrast their videos is by doing a video like Hysteria which is just a straight narrative with no cutting to the band and then they would do a video like Hyper Music which is purely the band in their element.
 And when they do videos like Hyper Music it allows them to be themselves and portray themselves the way they want to be seen to there target audience

1. Foo Fighters

Foo Fighters who share a very similar target audience to Muse reach their audience by using celebrity cameos for example 
 

Foo Fighters - Learn to Fly, in this video they draw their target audience in by having celebrity cameos they have Jack Black and Kyle Gass for are famous for being the duo that make up the comedic Rock band Tenacious D, Jack Black also famous for being in School of Rock and many other movies but this would attract their audience as they would most likely be fans of Tenacious D if they are a fan of Foo Fighters.

2. Radiohead 
Radiohead are very similar to Muse and have a very similar target audience however they reach their target audience by making their videos a lot more simple and minimalistic making it all about them as a band and how they want to be seen for example:
 

Messages:
Muse tend to put across very complex messages which I think reaches a wide range of their target audience. They often have messages of uprising and rebelling against corrupt Governments as well as very personal issues such as Alcohol addiction and other very personal issues that they have been through.
