Has technology changed?

Technology has changed vastly over the 20 years, allowing an artist/ artists to make music videos, and the budget artists used to have has also dramatically changed. In recent times it is necessary to have a music video to accompany a single, however in the past this was not always considered. This issue is very contrevisional as many people still have mixed views on this, some belive that music videos have destroyed the music industry, while others say it has made it better as some people like visuals aids in a music video, especially when the lyrics are hard to comprehend and a music video can help this.
