Bloomberg Terminal launch (1981)
1981What Happened
Michael Bloomberg launched the Innovative Market Systems terminal in 1981, charging roughly $24,000 per year for a workstation that combined real-time bond pricing, news, and analytics. Salomon Brothers signed on as the anchor customer, validating the product. The terminal bundled data, workflow, and proprietary tooling into a single subscription.
Outcome
Adoption spread across Salomon's competitors within years as traders found themselves unable to interoperate without the terminal.
More than 325,000 terminals are in use globally by the mid-2020s, generating tens of billions in annual revenue and entrenching Bloomberg as Wall Street's default infrastructure.
Why It's Relevant Today
Anthropic is attempting a structurally similar play: bundle a model, third-party data, and workflow integration into a subscription that becomes infrastructure. The Moody's deal mirrors Bloomberg's data moat strategy.
