Almost11 years ago, stores likeTower Records and WherehouseMusic were mobbed withover 2.4 million people waiting to purchase N'Sync's NoStringsAttached album.
Today,music stores like those are almost non-existent, and those that arestill in business do not receive much foot traffic in theCD aisles.
The sales ofcompact disc albums have seen a significant decline since that record week in 2000. Nielsen SoundScan reported thatover 730 million units sold in 2000. In 2010, album sales hit anall-timelow of326 million units sold, includingdigitallydownloaded albums.
"Nobody wants togo through the trouble ofgoing to amusic store, finding and buying aCD, opening the package,etc. Now we justclick a buttonon theInternet and instantly havemusic," said KeeganGogerty, 22, a singer/songwriter and radio-TV-film student.
Digitallydownloadingmusichas played amajor role in the decline ofCD sales, but the biggestfactor is the illegaldigitaldownloading ofmusic.
Piratingmusichas beenon therise sinceNapster launchedits peer-to-peer file-sharingsoftware in 1999.Napsterwas known forallowing users toshare and trade theirMP3 files withoneanotherover theInternet for free.
Napsterwas later shut down after multiple lawsuits, butmore peer-to-peer outlets surfaced, suchasKazaa, Morpheus andLimeWire.
Peer-to-peer sharinghas grown fromMP3 sharing to multiple-file sharing andtorrent sharing.
"Idon'tblame people for not wanting to purchasemusic. If I want to support a band,I willattend their concerts or buy a T-shirt. That is where they receivethe most royalties anyway," saidCharlie Hatano, an advertising graduate student.
"Welive in a generation of simple living, thedigitalage,"Gogerty said.
Onlinemusic stores suchasiTunes andNapster give consumers the option to purchasemusicat theclick of a button.
However,Ashley Sutton,24, a psychologymajor,still buyscompact discs.
"Nothingbeats getting a newCD, reading the booklet and reading the lyrics," said Sutton. "I agreeInternetdownloading ismore convenient, but I find owning a physicalCD collection rewarding, rather than clogging up my computer withmusic Idownload."
The music industryhas tried to crack downon the peer-to-peer file-sharingsoftware programs, but people arestill using different forms of illegallydownloading or sharingmusic.
"I'll admit that I have hadfriends burn an album for me or copy them into my computer for myiPod," Sutton said. Making copies ofCDs, illegallydownloading the album and sharing,it isall the same.
In aninterview with USAToday.com, the Recording IndustryAssociation of America's (RIAA)CEO said illegalmusic sharinghas been "contained."
"I remember peopledownloadingone songat atime withNapster.More recently I have seen peopledownload10 albumsat the same speed they coulddownloadone song in 1999," Hatano said.

京都府警がWinnyを摘発して金子さんから「もうメンテしません」と念書を取ったりしている間にKaZaAをつくったNiklas ZennstromとJanus FriisはSkypeをeBayに売り抜けてJoostで快進撃。中国ではBlin.inがBitTorrentの50倍速いかはさておき、ユーザーベースを拡大し技術を磨いてる。日本の家電メーカーがデジタル化だ情報家電だダビング10だと役所や既得権者に振り回されている間にAppleや任天堂に追い越され、たっぷり税金を注ぎ込んだ東大や未踏ソフト事業で育った技術者はGoogleやIBMに吸い込まれ、といった構図を俯瞰してみると考えさせられる。
