My first thought was Bell Labs here. The lack of time pressure for research results sounds like a big reason why so much innovation happened—people could pursue projects that may not have immediately benefitted the company's bottom line, because Bell had money to throw. I think UNIX was an example of this, because MULTICS was a failure and Bell was wary of similar projects, but I might be wrong.
According to Kernighan in UNIX: A History and a Memoir, the Unix team was constrained with regards to hardware capital at the time of Unix's creation. The Multics team got to use a fancy GE-645 (36-bits!) while the Unix team had to beg for "cheaper" systems like the PDP-7 and eventually an 11. Thompson has a great quote about how ultimately he was thankful they didn't have as much money to play with as the Multics team did but at the time he was annoyed he had to beg for a PDP-11. Fun book!
Most of the Bell Labs fundamental breakthroughs had no path to commercialization at the time of their discovery. The transistor was discovered 12 years into Shockleys research on fundamental properties of semiconductors.
If commercialization had been considered before funding, the project would have never been approved.
Instead, Bell management took the view that they could find everything, and some of it might become a new market, maybe.
