It means that Netflix understands it’s not in the “business” of delivering DVD’s to your mailbox. It’s in the business of delivering movies to you. However, whenever, and wherever you want them.
How you define your business has everything to do with whether or not opportunity is obvious or elusive.
If satellite radio, for example, thinks its in the business of getting radio to listeners by satellites, it’s mistaken.
If the radio industry believes its in the business of owning towers or FCC-granted licenses, it is likewise mistaken.
Can you read between the lines the way Netflix did?
