In the case of Blockbuster though, it wasn't quite their fault. The VHS market was controlled by "rental pricing" which basically kept tapes priced too high for the average consumer to purchase when they first came out (they were about 100 bucks). Only Dinsye and family movies would be priced at a reasonable sale price (about $20) because they felt there was a market for them. This allowed Blockbuster and otehr rental chains to thrive. When DVD came out though, the studios were swayed by the arguments of the big retailers like
Walmart and
Best Buy to price them at an attractive level to purchase. They could encourage people to collect them since they took up less space and had more features. People no longer wanted to rent a movie for 4 bucks when they could own if for 15 or 20. I suppose Blockbuster could have adapted to become more of a seller, but they would have just been one of many in the market, and not as large as the Walmart/Target/Best Buy type places.
