3Com's Decline: Bad Strategy and Price Wars Killed a Networking Giant

3Com dominated network card sales during the 1980s and 1990s, commanding a $5.8 billion valuation at the dotcom boom’s peak. Founded in 1979 by Bob Metcalfe, co-inventor of Ethernet, the company built its reputation on expensive but reliable cards with strong driver support and U.S. manufacturing. The brand was so established that some enterprises restricted purchasing to only three approved vendors: 3Com, Cisco, and Intel.

The company’s decline began with a retreat from enterprise networking equipment, a move that generated no cost savings while alienating customers forced to switch to competitors like Intel. 3Com then invested heavily in dial-up modems and acquired US Robotics, paying premium prices for technologies with limited remaining market life. Between 2000 and 2005, the company posted no profits. Intel’s aggressive pricing eventually undercut 3Com’s expensive cards, eroding the very market segment that once generated half the company’s revenue. Partnerships with Huawei and manufacturing moves overseas proved insufficient to reverse the company’s decline.

Hewlett-Packard acquired 3Com for $2.7 billion in late 2009, with the company ceasing operations on November 11, 2009. HP discontinued the 3Com brand, using Aruba as its alternative networking label. When HP sells network cards under its own brand today, they are typically Intel cards with HP logos—a symbolic reversal for the company that once manufactured its own premium networking hardware. 3Com’s vintage cards remain popular with retro computing enthusiasts for their reliability and historical authenticity.
