USENET news was originally distributed via UUCP and dial up modems.
The first USENET connection to the ARPANET was through UC Berkley in 1980.
It wasn't until the late 80's that USENET started to migrate away from
UUCP and modems to NNTP and network links.
FWIW, I was a UUCP leaf node in the early 80's.
Wrong answer. Usenet was started under ARPANET in the early to mid
70's. Before that ARPANET was used mainly for email and ftp. The email
evolved into email lists, but something more was needed, which lead to
the forerunners of NNTP servers.
You have that exactly backward.
USENET started on dial up modem and as I said the first "network" connection
was through UC Berkley which had both. It took almost a decade for USENET
to transition to primarily network feeds.
These were very basic; really not much more than an open email reader.
No threading, for instance. But it served its purpose in that it
allowed people to post a message and have it retrieved. Later came some
niceties such as threading.
Pure babble.
You may have accessed it via a modem, but those of us who were on
ARPANET had direct access to it.
Yeah, after USENET had been around for years and years.
