You need a playhouse of innovation, but you also need a pipeline of taking that innovation and making lots of money/practical applications. And you need the interaction between people doing practical work and feeling limitations and the playhouse trying stuff out.
Bell Labs worked because AT&T had huge field operations, a huge automation problem (telephone switching and billing), and a huge manufacturing arm for telco equipment and customer equipment, and a reputation for solving problems related to communication. Small innovations easily contributed to the bottom line, and large innovations enabled massive expansion of communication. Also, there's a huge benefit from research being connected to scale --- Bell labs innovations were likely to be applied in AT&Ts businesses quickly which informs future innovation; if you're an unconnected playhouse of ideas, it's hard to know if your innovations can be applied.
For better or worse, things are less integrated now. Telcos still have large field operations, but they don't usually manufacture the equipment. Automation of telephone switching is so complete, I don't know if there are any operators anymore. Billing for usage is very limited.
You see some companies developing the processors in equipment they use and sell, which is more integrated than when it was all Intel/AMD/Qualcomm.
