For the past year, and culminating with the holiday shopping spree, flat screen HDTV sets have been selling like hotcakes. Judging by how hammered the stocks of HDTV manufacturers and sellers got, one would expect a flattening of the adoption curve for a good part of 2007. Indeed, come 2008 and the obligation for HDTV programming will be fact. However, should the manufacturers want to do anything about sales in the meantime, why not offer trade-in options for the current owners of perfectly fine, yet older, TV sets? This way, the upgrade decision can be accelerated for those late buyers held back more by the psychological cost of replacing something that works than the marginal economic cost.
