Downloads grew steadily in popularity after first being integrated into the chart in 2004. In early September the UK Official Download Chart was launched, and a new live recording of Westlife's "Flying Without Wings" was the first number-one. The first number one to chart without ever receiving a UK physical release was Coldplay's "Viva la Vida" in June 2008. As of 2012, very few songs are given a physical release, and almost the entire chart is released solely on digital download.
