From The NY TImes:
...But then came digital. And suddenly the film industry is wrestling again with the possibility that its most precious assets, the pictures, aren’t as durable as they used to be.
The problem became public, but just barely, last month, when the science and technology council of the Academy of Motion Picture Arts and Sciences released the results of a yearlong study of digital archiving in the movie business. Titled “The Digital Dilemma,” the council’s report surfaced just as Hollywood’s writers began their walkout. Busy walking, or dodging, the picket lines, industry types largely missed the report’s startling bottom line: To store a digital master record of a movie costs about $12,514 a year, versus the $1,059 it costs to keep a conventional film master.
