History of shadow profiles

  • 1990s – early 2000s: In the early stages of the internet, user data collection was narrow and straightforward. Websites tracked basic info like visit counts, and user profiles were based on the data knowingly provided by the users.
  • Mid-2000s: Social media platforms, like Facebook, MySpace, and LinkedIn, brought in a significant shift. They encouraged people to share vast amounts of personal info, laying the groundwork for more detailed user profiles.
  • Late 2000s: Advances in technology made it easier for companies to gather and analyze more diverse data, like where people go and what they do online.
  • Early 2010s: The term “shadow profile” started gaining traction in the early 2010s. People started to notice and talk about how companies, especially Facebook, were collecting lots of data, not only from users but also from their friends.
  • Late-2010s to present: After major scandals like Facebook-Cambridge Analytica, people became more aware of these practices. New laws like GDPR in Europe and CCPA in California were introduced to help internet users have more control over their data.
