Words have meaning. Proper word selection is integral to strong communication, whether it’s about relaying one’s feelings to another or explaining the terms of a deal, agreement, or transaction.
Language can be confusing, but typically when something is available to “buy,” ownership of that good or access to that service is offered in exchange for money. That’s not really the case, though, when it comes to digital content.
Often, streaming services like Amazon Prime Video offer customers the options to “rent” digital content for a few days or to “buy” it. Some might think that picking “buy” means that they can view the content indefinitely. But these purchases are really just long-term licenses to watch the content for as long as the streaming service has the right to distribute it—which could be for years, months, or days after the transaction.
