The story
"Invisible" is a song by Irish rock band U2. Produced by Danger Mouse, it was released as a non-album single on 2 February 2014. The song was unveiled in a Super Bowl XLVIII television advertisement, launching a promotion that offered the song as a free digital download in the iTunes Store from 2–3 February. For each download of the track, Bank of America donated $1 to (RED), an organisation co-founded by lead vocalist Bono, to fight HIV/AIDS. Ultimately, $3.1 million was raised during the 36-hour promotion. Since 4 February, "Invisible" has been available as a paid download that continues to benefit (RED).
