This document discusses the evolution of music videos from early promotional videos in the 1940s to the present day. It notes that early music videos were often artistic works or promotions for new products, but that now many artists create low-budget videos that involve fan participation on social media or pursue a purely artistic vision. The future of music videos is seen to involve fewer commercial concerns and larger budgets, instead prioritizing frequent, low-cost videos that emphasize an artist's creative vision and concept.
