What Happened to 3Com?

3Com was a dominant networking equipment manufacturer founded in 1979 that peaked at $5.8 billion during the dotcom boom, but declined after making strategic mistakes including abandoning its profitable enterprise networking business to competitors like Cisco. The company ultimately disappeared on November 11, 2009, after losing market share and profitability due to a series of poor decisions and competition from cheaper alternatives that eroded its once-trusted brand position.
