Access may be limited to one person or to a group of persons (for example, a family or a company). Alternatively, access may be limited to a particular computer, or to any computer accessed by a particular person or by a set of persons.
Grader A: hit
DRM that bound purchases to a person's account and a set of authorized computers was standard in 2009. Apple FairPlay limited playback to five authorized computers per account. The dominant stores all used such schemes.
Test: Routine use by at least 20% of the industry: FairPlay (iTunes, the largest US music vendor) limited access to five authorized computers per account.
Grader B: hit
This describes DRM access controls, and they were routine by 2009. Apple's FairPlay (2003-2009) limited purchased music to five authorized computers tied to a user's account, plus CD-burn limits. Access was tied both to a person (the account) and to specific machines. Group and family access schemes also existed, although Apple's own Family Sharing came later (2014).
Test: Mainstream test: 20% of digital media sales carry person- or device-bound access rules. The iTunes Store, the largest US music vendor by April 2008, sold all its music under FairPlay limits (five authorized computers) until January 2009.
