  16. 16. WHAT DO PEOPLE ILLEGALLY DOWNLOAD?<br />People tend to download mostly entertainment products such as music, movies, television shows and games. <br />All types of music is downloaded by people for free using trojan sites or open sharing. <br />Movies are posted on the internet usually from people in the United States and then they are easily accessed freely by people with an internet connection. <br />
  17. 17. Illegal downloading is not just restricted to visual entertainment. Audio and electronic books are accessed in this same manner. <br />The illegal downloading of text is becoming more and more of a problem. Harry Potter was released on the internet through sources still unidentified, that leaked vast slabs of text that were then downloaded and distributed. <br />Software is being illegally downloaded and is being used to service the stealing of documentations, passwords, bank details, personal details and supposedly secure information. <br />
  18. 18. Private documentation has also been leaked onto the internet and illegally downloaded by the wrong people, who have gone on to use the information for unsavoury purposes. <br />Not all illegal downloading is for the wrong reasons. Entertainment purposes tend to warrant people wanting to obtain music, movies and games earlier than their release date, because the dates are varied from country to country. Meaning there is an opportunity for people to do so. <br />
