I used to work for Thomson and we made specific RCA models for WalMart Black Friday sales. The TV's were feature stripped. Less input Sockets, features not existing in the software, no picture in picture, freeze etc. A bunch of the picture enhancement circuitry was not fitted on the PCB and the software would not offer the options. Anything that could be removed to give adequate performance for their price point was. So when you buy something in the Black Friday crush you are buying depreciated stuff, be it laptops, TV's or whatever. We had to get the software tested and ready to go for those TV's by the previous August to give the factories time to build the units to be shipped to WalMart. I asked why they did this and was told sales and marketing and anyone in the finance department just could not turn down an order for several 100,000 specially made TV sets. Ah the good old days.
