The first derivative, the actual sales delta from last year to this year, shows that digital TV sales are fairly even. Flat, in other words. Whereas analog TV sales are in steady and relentless decline. The second derivative, acceleration in sales, shows that the rate of change of sales for digital sets has gone from slight increase to slight decrease. And you and Mark are assuming that this second derivative will continue on this trend. As of today, however, the simple fact is that analog sales are way off compared to last year, whereas digital sales are only slightly less. Brinkley said over 23.4 percent less analog sales (hint: that means 3 sets sold this year for every 4 sets sold last year) and 1.7 percent less in digital sales (hint: that's 98 sets sold this year where 100 were sold last year). > But then a real statistician might detect that the rate of > change is not just increasing but that it is accelerating and > then all bets are off.

Brinkley's point was, if you bother to read his column, that the boom in digital sales has not happened. He has not made any claim about digital sales going down the tube, or are worse than analog sales. Quoting what Brinkley actually wrote: "Most interesting to me are these conclusions derived from the CEA figures. So far this year, 21 percent of all TV sets sold have been digital. But for the most recent week, ending Nov. 4, the percentage was just 20 percent. "This is just one week, and the difference is almost meaningless. But that, plus the drop in overall sales, does show that the public is not running en masse, in every greater numbers, to buy digital televisions. That makes me wonder about the Parks Associates claim that 'consumers are beginning to see the true benefits of HDTV.' That's easy to say, impossible to prove." My conclusion is that people are not interested in the boring old big analog CRT sets, or fuzzy RPTVs, but at the same time, they aren't seeing the prices of the new "digital" sets low enough yet to replace their big old analog TVs that cost only $200. Case in pooint, the 26" set I bought last year, for over $1200, still costs $900 this year. Hardly cheap enough to be seen as a replacement for an analog set that would cost less than $200 today.
