No Bell Atlantic in those days. It was "AT&T and Associated Companies" though it may also have been spelled out as "American Telegraph and Telephone."
Yes, operator was a very tough job, though for a lot of people, they considered it dues to get into the Bell System which was a GREAT place to work. Heck, I went to work at the Labs and expected to spend my whole life there. (At the announcement of splitting into AT&T, Lucent, NCR in 1996, I left, believing that they were history. They were but it took a few years to get there.
Yes, there were other companies; three that come to mind were "General Telephone" (GTE) mentioned above, which was a separate company, and others such as Cincinnati Bell and Southern New England Telephone (SNET) that were partially owned by AT&T.
Yeah losing Central...Direct Distance Dialing came to the USA in the early 1950s, and International DDD came in in the 1960s. Progress, progress...imagine if you had to phone an operator to make a cell call ;-)
AT&T had phenomenally bad management who could not transition away from a regulated monopoly. The company called AT&T is not -- it is Southwestern Bell who BOUGHT the corpse of the old long distance company, which had once been the largest manufacturing company in the world, and the world's largest employer.
