History

Historical Context

In March 2016 Microsoft launched Tay, a Twitter chatbot that learned from user interactions. Within 16 hours coordinated trolling forced it to spew racist and hateful messages, leading Microsoft to suspend the account and permanently shut the bot. The incident sparked ongoing AI safety debates and informs current regulatory pushes such as the 2018 EU AI Act proposal.
