TODO: Write it

"Consumer technology" meaning that the technology was generally available to the public for a reasonable cost. The Concorde example stretches this definition, but I'm leaving it.

Examples:
* '''Photography''' was cheaper but worse quality in the late 90s and early 2000s. Even in the 1920s, consumers had the ability to create extremely sharp photographs ([https://www.shorpy.com/node/27756 an example]).
* '''Music sound quality''' dropped in the late 90s and early 2000s because people used peer-to-peer networks to download 128kbps MP3s, rather than CDs.
* '''Transatlantic crossing times''': When the Concorde was flying, London to NYC was 3.5 hours. When it was decommissioned, the fastest that a member of the public could get between the two cities went up to 8 hours.
