DVD was adopted by movie and home entertainment distributors to replace the ubiquitous VHS tape as the primary means of distributing films to consumers in the home entertainment marketplace. DVD was chosen for its superior ability to reproduce moving pictures and sound, for its superior durability, and for its interactivity. Interactivity had proven to be a luxury consumer and collector favorite when the movie studios had released their films on laser disk. When the price point for a laser disk at approximately $100 per disk moved to $20 per disk at retail, this luxury feature became available for mass consumption. Simultaneously the movie studios decided to change their home entertainment release model from a rental model to a for purchase model. This allowed all fans to become collectors and pushed the movie DVD into a demand position that essentially made it the most successful consumer product of all time. (from Wikipedia.org)
