I can understand the confusion. I thought I could remember more technology companies with names ending in "com" (or "comm"), but all that come to mind are 3Com (now Cisco) and Worldcom (MCI). Others I can find are: Microcom, Freecom, Eurocom, Gericom, DASCOM, GENICOM, Dexcom, Omnicom, Paycom, Swisscom, Vodacom, Millicom, Mediacom, Bulsatcom, Escom, Vivacom, Classicomm, JCOM, and Finecom, but most of those I've never heard of.
