YouTube age.

 When YouTube came along in 2005 it started to: 

• give and still to this day gives the same distribution to everyone, it doesn't matter how many followers you have. 
• It also meant that artists could get money not only from selling the album but also from views they got from videos. 
• Due to YouTube videos became more interested and looked like a piece of art. 
• It was also a way of showing off band's or artists recording label and sometimes even A&R executive

Nowadays, the video that goes within the song is mainly made for the band to show off in a way and also, mainly for it to gain more followers and views. By making good quality, interesting music videos band/artist can now have not only an audience who enjoy the music but also people who enjoy the style/look of the artist/band. 

Here is an example of the first Megan Trainor's music video for the song -- "All about that bass".

It is clear that in this music video the main target it is to sell the look of the artist 

     

 and also to show that anybody type is good.   Here is even a comparison between smaller and bigger body types. Throughout the whole song, the is a reference to the fact that it does to matter what body type you have. The artist, Megan is also shown to the audience a lot during the music video. That is using the Star Image, Andrew Goodwin's technique.
