A few seconds of an ad here, a few seconds of a newscast there, combined with Jon Stewart's comedic commentary -- and voila! A modern-day mash-up that samples digital bits and pieces to create something new.
But where does one person's creation end another person's begin?
Though copyright holders certainly have the right to protect what belongs to them, in some cases, the so-called fair use doctrine allows the limited use of copyrighted material.
To be sure, fair use legalese is complicated stuff. But digital rights advocates, like the Electronic Frontier Foundation, argue the importance of defending the use of copyrighted video, music and other media when it's used for criticism, commentary, teaching and other creative uses.
In fact, it's so important that they've now turned to a tried-and-true weapon – public shame – to hit back at companies that they say overstepped their bounds.
EFF's online " "Hall of Shame" spotlights high-profile examples of what it considers violations of copyright and trademark law.
"Free speech in the 21st century often depends on incorporating video clips and other content from various sources," EFF staff attorney Corynne McSherry said in a statement. "It's what 'The Daily Show with Jon Stewart' does every night. This is 'fair use' of copyrighted or trademarked material and protected under U.S. law. "
Sometimes companies are justified in asking Web sites to take down content that belongs to them. But online rights advocates argue that, increasingly, they are going too far, demanding the removal of Web videos or music even when they could have been protected by fair-use and free speech laws.
"The fact of the matter is takedowns are happening all over the place for all sorts of things," said Richard Esguerra, a spokesman for EFF. "The Hall of Shame is meant to highlight some of the most egregious – the situations where the copyright owner really should have known better or a copyright owner is being particularly bullying."
Whether or not the "Hall of Shame" discourages takedown abuse remains to be seen. But the Electronic Frontier Foundation says it will update the list regularly, and help people served with takedown notices learn if and how they might be able to dispute a removal request.
Here are a few of their "honorees":
First up: National Public Radio, for contesting last week the use of an excerpt of one of its reports in an ad produced by Stand for Marriage Maine.
The report, "Massachusetts Schools Weigh Gay Topics," originally aired in 2004, but was used in a recent ad meant to encourage Maine residents to veto a same-sex marriage law in an upcoming vote.
After a listener pointed out the ad, NPR sent takedown notices to YouTube, Stand for Marriage Maine and others. Though the advocacy group complied with part of NPR's request, the ad is still on the organization's site and on YouTube.
EFF maintains that the ad would be protected by fair-use standards as an example of free speech.
But NPR argued that because the ad relied so heavily on its content, and had the effect of undermining the journalistic value of the work, it did not meet fair-use standards.
