The DRM industry (recording companies, RIAA, Macrovision) have been awfully scarce on public benefits of the technology, but there's a quote snippet from 2003:
To make the new discs more palatable, Adam Sexton of Macrovision Corp., which makes copy-protection technology for music and movies, says they should be loaded with extras, such as live recordings or music videos. Consumers should expect to receive more when they put the disc into a computer, not less, said Sexton, a marketing vice president.

That's what I've come up with by digging into old mentions on sites, in HN discussions, and Google Books. Actual benefits discussion is very hard to find, and criticisms began quite early.

Update:
There's also Macrovision's response to Steve Jobs, following Apple's decision to exclude DRM from the iPod (arguably a major factor in the latter's popularity, and path-paving for the iPhone):
DRM increases not decreases consumer value -- I believe that most piracy occurs because the technology available today has not yet been widely deployed to make DRM-protected legitimate content as easily accessible and convenient as unprotected illegitimate content is to consumers. The solution is to accelerate the deployment of convenient DRM-protected distribution channels—not to abandon them. Without a reasonable, consistent and transparent DRM we will only delay consumers in receiving premium content in the home, in the way they want it. For example, DRM is uniquely suitable for metering usage rights, so that consumers who don't want to own content, such as a movie, can "rent" it. Similarly, consumers who want to consume content on only a single device can pay less than those who want to use it across all of their entertainment areas – vacation homes, cars, different devices and remotely. Abandoning DRM now will unnecessarily doom all consumers to a "one size fits all" situation that will increase costs for many of them.
