And about film

=========

Those who could afford such luxuries could buy a 16 mm or 8 mm film projector and rent or buy home-use prints of some cartoons, short comedies and brief "highlights" reels edited from feature films. In the case of the 16 mm format, most of these were available with an optical soundtrack, and even some entire feature films in 16 mm could be rented or, at a steep price, bought. 8 mm films almost never ran longer than ten minutes, and only a few were available with a magnetic soundtrack late in the life of the format; the rest were silent. The Super 8 film format, introduced in 1965, was marketed for making home movies but it also boosted the popularity of show-at-home films. Eventually, longer and longer edited-down versions of feature films were issued, increasingly with a magnetic soundtrack and in color, but they were quite expensive and served only a small niche market of very dedicated or affluent film lovers.

Blu-ray has failed, because it has not replaced DVD's, or become the primary format for most releases. Digital releases have, and will overtake it.
