Striking the 1976 act
Jason Schultz has done more amazing work calculating any “chaos” that would come from striking the 1976 Act. Using the Internet Movie Database, he confirmed the Copyright Office’s numbers that about 37,000 movies were released in the period 1927-46. (IMDb reports 36,386). Of those, only 2,480 are currently available in any format, or 6.8%. 93.2% of the films during that period are are commercially dormant.
