Founded in 1979, 3Com initially focused on developing networking products based on the Ethernet protocol. It became a pioneer in the field of local area networking (LAN) and introduced several groundbreaking products over the years. The company's prominence grew during the 1980s and 1990s, especially with the rise of networking in businesses. However, after facing increased competition and market challenges in the 2000s, 3Com underwent several changes, including acquisitions and eventual divestitures. In 2010, 3Com was acquired by Hewlett-Packard (HP), marking the end of its independent operations.
