History

Historical Context

Google’s 2014 purchase of DeepMind for about $400 million marked the first major corporate acquisition of a pure-AI lab, prompting Google to embed DeepMind’s research into its services and spurring cloud-AI competition. That precedent underlies today’s multi-billion-dollar AI deals, such as Amazon’s $50 billion pledge to OpenAI and Microsoft’s revised revenue-share with OpenAI.
