How has digital technology impacted on the exhibition/consumption of music promos?

Digital technology has impacted on the exhibition/consumption of music promos as it has improved over the last 40 years.

People can view music promos on the internet, especially on YouTube, which has impacted the consumption of music promos as now people can watch the music promos whenever/wherever they want to, instead of having to watch them on a music channel where they might not actually get to see it at all or after a while.

The artists can put their videos online on places such as YouTube, their own website or social networking sites as well as on TV/radio. This has impacted the exhibition of music promos as the promos will get viewed by a larger audience as the artists aren't limited to TV/radio stations to get the music promo press coverage or attracting record labels and an audience as they can now post online to a worldwide audience.
