Sure, I wouldn't argue the businesses were identical, though I don't expect that the DVD rental Netflix looked anything like the streaming Netflix.
Where Blockbuster would have moved from brick and mortar to streaming, Netflix would have been moving from mostly a logistics business with warehouses in the middle of nowhere to a streaming/tech business.
