What is ActiveX? 

"ActiveX is the consumer brand name for all Microsoft COM-based technologies.... Tylenol is an easy-to-remember, more consumer-friendly brand name for a drug called Acetaminophen. In this same way, ActiveX is an easy-to-remember, more consumer-friendly name for COM. ActiveX certainly sounds much cooler than COM.

......

The reason so many people are confused by the name ActiveX is because the definition changed. Originally ActiveX was a brand name for all COM-based Microsoft technologies that had utility on the World Wide Web."

---- Alan Gordon (The COM and COM+ Programming Primer)

COM = Component Object Model
