Nearly 150 issues of Nintendo Power were pulled from the Internet Archive after Nintendo issued a DMCA notice. The issues, which included comics, walkthroughs, tips, cheats, and more, were uploaded seemingly without the company's knowledge by digital archivist Jason Scott and have since been removed. Though a common practice for old, out of print magazines, the Nintendo felt that allowing the archive to remain in operation would hinder its ability to protect its copyright.
Nintendo's official statement reads:
Nintendo’s broad library of characters, products, and brands are enjoyed by people around the world, and we appreciate the passion of our fans. But just as Nintendo respects the intellectual property rights of others, we must also protect our own characters, trademarks and other content. The unapproved use of Nintendo’s intellectual property can weaken our ability to protect and preserve it, or to possibly use it for new projects.
While taking down this piece of inaccessible gaming history might seem like a dirty move on Nintendo's part, the fact is that copyright law in the United States is largely incomprehensible and insane. Intellectual property doesn't enter the public domain for 70-120 years after the death of the original creator (in fact, the work of novelists who died in 1945 are only now entering public domain!). If Nintendo did allow the archive to remain up, it could open a crack in their defenses if they need to protect their copyright from profiteers in the future.
