Comparison of 1989 music video and 2012 music video

Here are two videos of a similar genre that i have chosen to compare, Van Morrison- 'Have I Told You Lately' an Ed Sheeran- 'Small Bump'. Van Morrison's song was released in 1989 and Ed Sheeran's in 2012, this contrast will show the difference in music videos between each era, and how music videos have progressed. The most visable contrast between both music videos is the diffence in quality of the image, this shows how cameras are progressing and images are becoming more clear. However a similarity is that they both have a hint of narrative and story to them which is typical for this genre of music. When comparing both music videos it is clear that there are some differences due to the advance of technology, however the theme, layout and ideology are very similar and have not changed that much over time.
