1977 - Development of the VCR

The first magnetic videotape recorder was demonstrated by Bing Crosby Enterprises in 1951.   Its use was purely for movie production purposes.  Although it performed poorly, it was predicted that such a recorder would eventually allow full color pictures and sound to be recorded on one strip of tape. RCA followed the next year with a demonstration of a color videotape recorder, but this demonstration was quickly overtaken by consumer interest in the television market.

Sony introduced its first Betamax machine for mass consumer use in 1975 for an initial price of $1,300.  With this introduction, consumers had the opportunity to record their own programming and move into the world of home movies. In 1977, Sony's monopoly ended when Japan Victor Company (JVC) introduced the VHS format video cassette recorder (VCR), that allowed consumers to record up to six hours on a single tape. RCA introduced VHS machines and were shortly joined by Panasonic (Matsushita). These machines offered a cassette format that was technically incompatible with Sony's Beta machines, forcing consumers to make a choice between the two formats

2015 - Digital Movie Purchase and Rental

With the gains in information transfer (BK3 Technology) at speeds of 2.0 megs per second and the success of the Internet dollar, consumers now purchase and rent digital films and music solely through the web.  The local Blockbuster or hometown video store has been overrun by the ease of BK3.  Consumers "shop" for titles and can rent with the option to purchase within 10 days.  After this 10 day wait, the film self deletes if the user does not enter the mastered code.  Download time for films are 2-3 minutes and are saved on hyper-CDs.  This change in industry sales saved retailers like Blockbuster millions of dollars, and continues the downward spiral of American physical fitness, as they sit in front of their grid and pig out on the new fad: Bologna flavored Doritos.
