The soulful 2007 album "Back to Black" by the late Amy Winehouse was the highest debut for a British solo female singer on the Billboard chart -- until Joss Stone charted even higher just one week later.
2007 was the year that digital downloads became eligible for the UK singles charts even without a physical release. Big winners from that change included Nelly Furtado's "Man-eater", which returned to the charts and went gold thanks to downloads.
The new chart rules meant in theory any song available digitally could feasibly chart, given enough support. So British DJ Chris Evans mobilised his listeners behind "Honey to the Bee" by Billie Piper -- released in 1999 when she was a teen pop star, long before "Doctor Who" -- and the song duly surged to No. 17 on digital sales alone.
One step ahead of the explosion in digital communication heralded by the iPhone, US President George W Bush signed a law that allowed spies to eavesdrop on American citizens without a warrant. Of course, thanks to Edward Snowden we'd later learn that this was just the half of it.
Following Britney Spears' performance at the 2007 MTV Video Music Awards in September, fan Chris Crocker posted a tearful video titled "Leave Britney Alone!" on YouTube. It became an early viral video hit.
