[15] Between 2002 and 2004, Mason connected RWD's online director Lex Johnson and illustrator Art Jaz to create the animated adult sitcom series The Booo Krooo.

[16] In 2005, Mason moved to New York and began working on his first book, The Pirate's Dilemma, watch was published by Simon & Schuster in the US[17] and Penguin in the UK[18] in early 2008.

[25] In the book, Mason makes the case that the best way to beat piracy is to compete with it, by determining the value pirates are creating and coming up with legal alternatives.

Linkin Park used bundles to distribute a free trial of its recording software, StageLight, and soon after saw a 200% increase in the number of upgrades to the paid version.

[39] The company anonymously posted billboards in San Francisco, New York, and Los Angeles depicting controversial statements such as "Your Data Should Belong to the NSA" and "The Internet Should Be Regulated".

[40] After several weeks of media confusion, including an investigation by the LA Times,[41] Mason revealed in a blog post that BitTorrent was behind the ads.

"With the reveal, we are showing people that things don't actually have to be like that", Mason told Mashable in an interview, referring to the original bleak messages.
