Have you ever gone into a Best Buy or similar and seen the cable selection? The "cheap" cables are $50, and the Monster cables are sold right beside them. Many people compare prices on the TV before coming into the store, but are not armed with good information when the salesperson tells them that their $1200 TV is worthless without $250 in cables.
It's more insidious at a Best Buy where large purchases like HDTV with accessories are often financed and the salesperson says they can have the best without paying for it (right now).
The average consumer has no clue and doesn't want to learn that digital is digital, not like analog. All they know is when there is poor signal they get nothing on their TV (or blocky) where on their old TV they at least got a viewable picture with noise.
