Tow Center: Platforms and Publishers: A Definitive Timeline
Editor’s note: Columbia Journalism School’s Tow Center for Digital Journalism has produced a timeline of developments at major platforms such as Google, Facebook, Instagram, Snapchat and so on. It goes back to 2000. This is a good resource for keeping tabs on how what these major platforms are developing.
