The five most important moments for digital music

Napster starts it all
In 1999 Napster became first music file-sharing service to make digital downloading a viable, and illegal, option for finding new music. The end came in 2001 after a law suit from the Record Industry Association of America, though Roxio resurrected the name in 2003 in an all new legal (ie paid for) format.
iPod launched
Though Rio had dipped their toes in the digital audio player market, it was the iPod’s launch in 2001 that made an entire record collection pocket-sized. iTunes followed soon after, selling 70 million songs in its first year. That number’s now up to 4 billion in total, though half of those are Coldplay.

Downloads take over the charts
2005 saw the industry wake up to increased online purchases with downloads now contributing towards the UK Singles Chart. Gnarls Barkley became the first act to get to number one on downloads alone with ‘Crazy’ in 2006, though it’s Lady Gaga’s ‘Pokerface’ that holds the title for the UK’s most downloaded song. Technology doesn’t come with taste.
Radiohead release In Rainbows
Never ones to play it safe, Radiohead become marketing innovators on sixth album, In Rainbows by letting fans choose their own download price. Being Radiohead, millions lap it up, with an average price of £4 paid for the Grammy winning album. Contemporaries like Nine Inch Nails follow suit, though Blue are undecided.
The dark side
After copy protection on CDs proved unworkable for the big four record labels, they, along with the RIAA, take to the courts to protect their music. June 2009 saw Minnesota mother of four Jamie Thomas-Rasset ordered to pay $1.92 million for violating copyrights on 24 songs. That’s $80,000 a song. Even the one by Linkin Park.
