I attended the IBM Connections conference in Vegas shortly after the Jeopardy! thing and just after IBM started using Watson as a brand under which it lumped a bunch of analytics products. From questions and comments made, during some of the sessions I attended, it became clear that large portion of the attendees (mostly the business people) wrongly assumed that the technology that won Jeopardy! was now being used inside everything labeled with "Watson". People were very excited by this. I never heard anyone from IBM making any attempt to try and rectify this misconception, they just smiled, nodded and played along.
I disliked IBM and their corporate marketing BS even more after this.
