What does Broadcom actually make, and why does it seem to affect so many tech products when something goes wrong with the company?

Broadcom is a semiconductor and infrastructure software company that designs and sells chips and software used deep inside the products that most consumers and businesses rely on every day. On the hardware side, they make networking chips, Wi-Fi and Bluetooth controllers, storage controllers, fiber optic components, and specialized processors used in data centers, routers, smartphones, and enterprise equipment. On the software side, after acquiring CA Technologies and Symantec's enterprise division, they also sell mainframe software, cybersecurity tools, and IT management platforms used by large corporations and governments. The reason disruptions at Broadcom ripple so widely is that their components sit at critical junctions in technology infrastructure rather than in consumer-facing products. When your home router connects to the internet, there is likely a Broadcom networking chip handling that traffic. When a data center processes cloud workloads, Broadcom switching chips are often moving data between servers. Apple has used Broadcom chips for Wi-Fi and cellular components in iPhones for years. Essentially, Broadcom occupies chokepoints in the supply chain where a single chip design might end up in products from dozens of different manufacturers. Their 2023 acquisition of VMware added another layer of reach, since VMware's virtualization software runs a substantial portion of the world's corporate server infrastructure. Many businesses run their entire IT operations on VMware products, so changes to licensing or pricing after the acquisition caused significant concern across industries. This combination of being embedded in physical hardware and controlling essential software platforms means Broadcom's business decisions or any operational problems can cascade across an unusually broad range of technology products and services simultaneously.
