How the Bloomberg Terminal Changed Wall Street Forever

A Brief History of the Bloomberg Terminal

How the Bloomberg Terminal Changed Wall Street Forever

In 1981, after being fired from Salomon Brothers, Michael Bloomberg founded Innovative Market Systems to build a terminal that combined real-time data with instant analytics. The first Market Master terminals, delivered to Merrill Lynch in 1982, gave traders an unprecedented window on global markets. The terminal evolved from a closed network with a custom keyboard to a subscription-based service costing over $32,000 a year, becoming an icon of financial power.

For nearly two decades, Bloomberg Terminals commanded an aura of power and financial prowess. They were emblems of market mastery, with a brand that was distinct from other office computers.

    I have the highest regard for these terse, but information-dense displays that enable humans to quickly grasp all information they need to do their jobs, and nothing more. This is also something avionics provide - a modern cockpit displays are a work of art in layering needed information for what is happening at the time, both the dense PFD and the much specific that communicate aircraft status.

    For completeness' sake, here's also a history of competitor REUTERS' terminal:

    The modern Terminal is based on a private fork of Chromium to give it the look and feel of a VT100 terminal, and integrate their private networking and security technologies. The BBT predates HTTP, and backwards compatibility is hugely important to the company- they have a museum where a second-generation Terminal from ~1985 shows the current news, because they are so dedicated to backwards compatibility that they still can support the 1985 hardware.
