FactSet

An old proprietary database where mostly Wall Street investors and management consultants would find data.

FactSet housed the sellside analyst reports when they came out to the world, changing their earnings estimates from 14 cents next quarter to 18 cents. FactSet would have enough granular detail to basically "show the work" of the analysts who generated those spreadsheets. But alas, the internet came along and data distribution grew very liquid, so today, brokers more or less just email their clients with the info they want them to have, and both people who still use FactSet find its servers very fast.
