The DRM graveyard part 2: A brief history of digital rights management in video and TV
A few months ago, we outlined a few of the major moments in the history of digital rights management (DRM) in the music industry. This time, we're talking about TV, video, and the events in the ongoing fight over copying. We're still calling it the "DRM graveyard"--but as you'll see, the failures that DRM has seen in the music world aren't quite yet as plentiful when it comes to video.
President Franklin D. Roosevelt signs the Communications Act of 1934, creating the Federal Communications Commission (FCC) to regulate broadcasting.
Sony introduces the Betamax video recorder, which Sony founder Akio Morita describes as enabling consumers to "time-shift" their television watching.
In what becomes known as "the Betamax case," Universal Studios and Walt Disney Productions file a lawsuit against Sony for copyright infringement by the Betamax device, seeking to prevent its sale. The court rules in favor of Sony, stating that private recordings are fair use. Annual sales of VCRs are around 30,000 for the year.
The US Court of Appeals reverses the decision in the Betamax case. Annual sales of VCRs have reached 1.4 million (and shifted largely to VHS format over Betamax).
The Home Recording Rights Coalition forms on October 22 (the day after the decision that makes selling the Betamax VCR illegal) to "preserve consumers’ rights to record and to share in the benefits of technological advances."
Macrovision forms. This company develops anti-recording technology for VHS (Betamax is unaffected by their technique).
The Supreme Court rules in Sony Corp. of America v. Universal City Studios, Inc. that recording TV shows to watch later does not constitute copyright infringement and that the makers of the recording devices--i.e., VCRs and Betamax--cannot be held liable for infringement.
The film The Cotton Club is the first video to be encoded with Macrovision protection.
The motion picture industry pushes Congress to enact legislation to require anti-recording electronics in VCRs as a part of a larger anti-recording effort that is mostly related to DAT recording and devices.
Senator Herbert Kohl (D-WI) and Representative Howard Berman (D-CA) introduce the eventually unsuccessful Motion Picture Anti-Piracy Act, which would amend the Electronic Communications Privacy Act to make it illegal to manufacture devices or do anything to "avoid, bypass, deactivate, or otherwise circumvent the process, treatment, mechanism, or system used by the owner of a copyright to prevent or inhibit recording."
The National Information Infrastructure (NII) Copyright Protection Act of 1995 (H.R. 2441 and S. 1284) is introduced. It would make it illegal to import, make, or sell any device whose primary purpose is circumventing anti-copying measures and effectively reverse the Betamax case decision. It fails in October 1996.
Content Scramble System (CSS) is introduced with a 40-bit key size. It has long been used on most commercial DVDs, although newer DRM techniques are now often employed.
The World Intellectual Property Organization (WIPO) Copyright Treaty is signed, creating additional copyright protections not covered previously due to technological advances. It becomes effective in March 2002.
Intel, IBM, Matsushita, and Toshiba join together as 4C and create Content Protection for Recordable Media (CPRM).
ReplayTV and TiVo unveil their digital video recorder (DVR) products at the Consumer Electronics Show.
President Clinton signs into law the Digital Millennium Copyright Act (DMCA), making DRM circumvention and circumvention tools illegal.
Jon Lech Johansen ("DVD Jon") and two anonymous collaborators ("mdx" and "the nomad") reverse engineer CSS and create DeCSS, releasing it on the Linux Video (LiViD) mailing list.
President Clinton signs into law HR 3456, the Digital Theft Deterrence and Copyright Damages Improvement Act of 1999. It increases the minumum statutory damanges for copyright infringements from $500 to $750 and the maximum from $20,000 to $30,000. For willfull infringement, the maximum increased from $100,000 to $150,000.
One of the earliest lawsuits testing the DMCA is filed: Universal City Studios, Inc. v. Reimerdes. Universal, Paramount, MGM, Tristar, Columbia, Time Warner, Disney, and Twentieth Century Fox sought an injunction against the publishers of 2600: The Hacker Quarterly for distribution of DeCSS.
Studios awarded an injunction in Universal City Studios, Inc. v. Reimerdes. The decision is affirmed by the US Court of Appeals in 2001.
The DMCA's prohibition on circumventing access control becomes effective. The Library of Congress (with direction from Congress and the Register of Copyrights) in the first of its every-three-years rulemaking sessions, declares two classes of works exempt from this anti-circumvention provision. The two classes are "compilations consisting of lists of websites blocked by filtering software applications" and "literary works, including computer programs and databases, protected by access control mechanisms that fail to permit access because of malfunction, damage, or obsoleteness."
The Broadcast Protection Discussion Group forms to create a proposal for how electronics manufacturers can build in protection for digital boradcasts. The result comes to be known as the "broadcast flag."
Scott Crosby of Carnegie Mellon University with Ian Goldberg, Robert Johnson, Dawn Song, and David Wagner present a paper at the ACM-CCS8 DRM Workshop titled "A Cryptanalysis of the High-bandwidth Digital Content Protection System." In it they examine the weaknesses of HDCP and explain how to eavesdrop on data, clone devices, and more.
Senator Ernest Hollings (D-SC) introduces the Consumer Broadband and Digital Television Promotion Act (S. 2048), which requires electronics that receive, record, or even store copyrighted data to honor the copy protections on that content. Penalties for manufacturers or consumers could include up to five years in jail or $500,000 in fines. It fails after significant opposition from the IT industry, led by Intel.
By the DMCA, all VCRs must be manufactured with Automatic Gain Control circuitry, and thus be affected by Macrovision copy controls.
The European Parliament passes the Copyright Directive to implement the WIPO Copyright Treaty, similar to the DMCA in the US, with narrow exceptions to anti-circumvention measures.

Jon Johansen works further on various video formats and programs, including DeDRMS, FairKeys, and support for FairPlay and WMV9 in VLC.

Senator Orrin Hatch (R-UT) introduces the Inducing Infringement of Copyrights Act (INDUCE Act), which targeted peer-to-peer filesharing, stating, "Whoever intentionally induces any violation identified in subsection (a) of this section shall be liable as an infringer."

The exemptions now include "audiovisual works included in the educational library of a college or university’s film or media studies department, when circumvention is accomplished for the purpose of making compilations of portions of those works for educational use in the classroom by media studies or film professors" and "sound recordings, and audiovisual works associated with those sound recordings, distributed in compact disc format and protected by technological protection measures that control access to lawfully purchased works and create or exploit security flaws or vulnerabilities that compromise the security of personal computers, when circumvention is accomplished solely for the purpose of good faith testing, investigating, or correcting such security flaws or vulnerabilities."

AACS has spent months issuing letters demanding sites that publish the HD-DVD key to remove it and links to it. Digg began revoking user account and taking down posts about the key. Its community had an overwhelming response. (Digg stopped deleting users and stories about the keys.) The key then made its way into art, comics, t-shirts, tattoos, and more, in a popular example of the "Streisand effect".
