2011 pushes one demographic segment into the next -- confounding marketers.  The terms 'seniors' -- and senior citizens, elderly, aged, older adults -- and various other monikers have been around for a long time. But it's a new year. This year, as 10,000 per day (680,000 this year so far) of those trend-shaking baby boomers turn 65 and become eligible for Medicare, seize on any remaining 'senior citizen' discounts, and view next year's eligibility to take full Social Security, the pre-senior baby boomer population will dwindle by more than 3 million. And so on for the next 18 years.  How can marketers straddle both sides of the boomer-senior divide at the same time? Perhaps they will attempt euphemistic subtlety - especially since everyone knows that baby boomers don't want to see themselves as old (or as represented by any of the above terms). So step one for vendors -- stop describing and marketing products by age category, so required and peculiar to the tech industry. Unlike cars, light bulbs, washing machines, radios, even bicycles with comfortable seats, where vendors don't know who might buy them, they market to all ages to be safe.

Watson: that Jeopardy win was a good beginning -- real win is ahead.  In a computer science building at Carnegie Mellon University last week, it was cute to watch the students file into a room to watch the last Jeopardy round on TV. So by now you know that IBM's super computerized multi-year Jeopardy effort paid off and Watson handily beat the two best human Jeopardy players. So what's Watson's next act? Soon, say IBM folk, Watson's tech will be commercialized within healthcare apps: "We're going to look at creating a product offering in the next 24 months that will help empower doctors to do higher quality decision making and diagnoses."  Interesting -- and even more so while thinking about Andy Kessler's WSJ analysis of the types of jobs threatened by technology, including the roles of today's doctors.
