The Wireless Festival takes place every year in London, England. It is owned and managed by Live Nation. While it started as primarily a rock and pop festival, in recent years it has focused on hip-hop and other urban music. Headline acts since 2010 have included Jay-Z, Kanye West, Justin Timberlake, Rihanna, Bruno Mars, and Stormzy.
From its inception in 2005 until 2008, the festival was sponsored by telecommunications company O2, and was called the O2 Wireless Festival. From 2009 to 2012, the main sponsor was Barclaycard and the festival renamed to Barclaycard Wireless Festival. For 2013, the sponsor changed to Yahoo!, and was renamed to Yahoo! Wireless. Since 2015, the sponsor has been the fashion retailer New Look.
