An attempt at blocking an HD-DVD key from being published on Digg caused uproar when cease-and-desist letters demanded that the code be removed from several high-profile Web sites. This led to the key's proliferation across other web sites and chat rooms, in various formats, with one commentator describing it as having become "the most famous number on the Internet". Within a month, the key had been reprinted on over 280,000 pages, and had appeared in a song on YouTube which had been played over 45,000 times.[15][16][17]
