Q. A Jolly Roger formed from the silhouette of a Compact Cassette along with the words "And It's Illegal" (as depicted in the picture) was the logo of an iconic 1980s anti-copyright infringement campaign by the British Phonographic Industry (BPI), a British music industry trade group who promulgated their campaign with a catchy slogan "Home Taping Is Killing Music" as they feared that people being able to record music from the radio onto cassettes would cause a decline in record sales.
Funnily enough, the "Home Taping Is Killing Music" logo is a striking feature in the logo of one of the most popular and controversial internet file-sharing website, even though it completely defies the ethics of the campaign, thereby creating an interesting specimen of irony. Which website am I talking about?
