There are few franchises in the silicon business where one vendor so completely dominates the market. Everyone can name Intel’s CPU business as one. But can you name another?
Infineon/TI (IFX) in DSL is a contender. Conexant (CNXT) in PC modems (but little profit to show for it). Netlogic (NETL) in exotic CAM’s (but beholden to one sugar daddy customer - Cisco).
But nothing approaches the complete and total dominance of Broadcom’s (BRCM) grip on Ethernet switching silicon.
