As 'Best Buy' gears up for its important high-definition TV sales months, a new survey from the No. 1 electronics retailer reveals that almost 90 per cent of Americans still don’t understand HDTVs – and close to 50 per cent underestimate the cost of buying one.

“We were getting a lot of anecdotal evidence that showed consumers were frustrated with their HDTV purchases,” Mike Mohan, vice president of merchandising at Best Buy, told CNNMoney. “We felt that we had some gaps in key area of consumer education. That’s why we decided to commission this study and really understand where the issues were.”

The survey, which polled 1,012 consumers nationwide found that 89 per cent of people said they lacked a complete understanding of HDTV technology. Best Buy also said 48 per cent of consumers didn’t budget appropriately for the “entire” HD experience.
