The Grammy Awards Sunday night were watched by 26.66 million viewers, the largest audience for the ceremony in 11 years. Viewership was up by three percent from 2010, and the broadcast performed better in the 18-to-49 demographic than it had since 2004.

Unsurprisingly, the large audience resulted in a sales bump for some of the big winners and less famous acts featured in the broadcast. Full sales figures will not be available until next week, but according to Eric Garland of the digital research firm Big Champagne, preliminary data from iTunes reported spikes in sales for Song of the Year and Record of the Year winner Lady Antebellum, Album of the Year winner Arcade Fire and surprise Best New Artist winner Esperanza Spalding.

The British folk rock group Mumford & Sons also saw a significant boost in digital sales after their performance with Bob Dylan and the Avett Brothers. According to their American label Glassnote Entertainment, sales of the band's album Sigh No More increased significantly, pushing it to the top of both iTunes and Amazon's digital album charts.
