It's an interesting parallel because part of the unspoken agreement between AT&T and the feds was that they had their monopoly, but had to use the funds for some kind of public good. Bell Labs was part of the public good - and why they employed multiple physicists and materials scientists whose employment involved basically researching whatever they wanted as long as it had some link back. Shannon was hired after his master thesis (which basically created the field of information theory) and, among other things, had a side project involving the application of computers to chess. They constructed the New Jersey lab specifically to encourage watercooler conversations and deliberately had greenhorns to work with the most senior researchers like Shannon. Bell Labs solved engineering problems needed by AT&T and Westinghouse, but they had the financial security to spend money on incredibly theoretical projects like transistors, operating systems (unix), and programming (C). Those pie in the sky projects would both benefit AT&T through automation, and covered the public good requirements of their monopoly.

AT&T (owner of Westinghouse and Bell Labs) then proceeded to take their monopoly and patent factory, and started buying up competitors and new small companies. Eating their golden goose in this way is what caused the government to break them up.

Bell Labs was independent for a few years doing... Stuff. Spent their remaining prestige on falsification scandals because of the publish or perish culture this new profit motive created. They were bought by Nokia a few years ago (now called Nokia Bell Labs) and now only employ a couple theoretical physicists last I read. The lab that put into practice the foundations of modern tech (Unix and C are in almost every non-consumer-facing device) just does some Nokia product development nowadays. What a loss.
