A great paragraph from Henry Jenkins
History teaches us that old media never die. And before you say, “What about the eight-track,” let’s distinguish among media, genres and delivery technologies. Recorded sound is a medium. Radio drama is a genre. CDs, MP3 files and eight-track cassettes are delivery technologies. Genres and delivery technologies come and go, but media persist as layers within an ever more complicated information and entertainment system. A medium’s content may shift, its audience may change and its social status may rise or fall, but once a medium establishes itself it continues to be part of the media ecosystem. No one medium is going to “win” the battle for our ears and eyeballs.
