The volume of data, and the required speed of transmission to stay
more-or-less current with the actual market conditions outstripped the
capability of 'tape' printers.

Just as _telegram_ printing shifted to roll-feed wide paper, from the
tape, what remained for dedicated mechanical printers did similarly.

In the 60s, early-70s ...

Bunker-Ramo came out with electronic quote display terminals, and
practically owned the _broker_ market for a number of years.

Telerate also came out with a CRT display supporting many, _many_
'pages' of display data -- everything from news stories to lists of
latest market prices -- either as groups displayed simultaneously on a
single 'page', or single issues as a streaming 'ticker' across the
bottom of the screen.
