The Bloomberg terminal is the perfect example of a lock-in effect
reinforced by the powerful conservative tendencies of the
financial ecosystem and its permanent need to fake complexity.
Simplifying the interface of the terminal would not be accepted by
most users because, as ethnographic studies show, they take pride
on manipulating Bloomberg’s current “complex” interface. The pain
inflicted by blatant UI flaws such as black background color and
yellow and orange text is strangely transformed into the rewarding
experience of feeling and looking like a hard-core professional.
