📡 Bell System at Its Peak

The Bell System (AT&T and its regional Bell companies) was a government-regulated telecom monopoly until its breakup in 1984.

• Revenue (early 1980s): ~$70–80B/year
  → ~$220–250B today, inflation-adjusted
• Employees: Over 1 million
• Market Cap (est.): ~$100–150B in 1980s
  → ~$300–400B today
• Market Share: ~90% of U.S. phone service
• R&D: Bell Labs (invented transistor, UNIX, lasers, info theory, etc.)

In short: Bell controlled the entire U.S. telecom backbone and set the pace for global innovation.
