But in the historical context that the word "Broadband" was used,
a print-ad from almost 40 years ago in late 1968, I don't see anything
wrong with such use!
At that time, 56K WAS INDEED considered BROAD-band by those who used
such capabilities. Back then during the 1960s and even into the 1970s,
Bell Labs, AT&T Long Lines, and the BOCs were trying to expand on
a *switched* 56K digital data service, but at the time, the only
active customer, with the possible exception of some specialized
government/military departments, was Maw Bell herself, to exchange
billing data among the various toll offices and RAOs, and AT&T's
Kansas City MO Traffic Routing Administration HQ, for processing
long distance charges to appear on customers' bills.
AT&T actually wanted to be THE provider of switched 56K high-speed
(at the time) data, with these highly specialized dataphone modems
and a "Special Area Code" to be assigned, as well as special routing
and trunking, similar to what was in place for still-at-the-time
AT&T owned-and-provided TWX, and what AT&T also hoped to provide for
a switched 2-way Picturephone service.
There was very little customer interest at that time for such a
switched high-speed data service, although PRIVATE LEASED use was in
demand, and also Antitrust got involved to try to prevent AT&T from
having an almost total monopoly on providing both the SWITCHED aspects
of a public broadband or high-speed network, as well as the dataphone
modems for such. With the exception of AT&T's own "in house" use of
*switched* 56K data service for routing billing messages back and
forth between AT&T-LL in KC MO, and the BOCs and some of the larger
independents, such *switched* 56K data really didn't get off the
ground that much until the mid-1970s.
And even though today, most of us wouldn't consider 56K to be "broad"
band, back then in the 1960s, 56K *WAS INDEED* "broadband", and it
did begin the continued development of higher speeds and larger
bandwidth over time.
