How did U2 get their name?

Larry Mullen originally described it as "'The Larry Mullen Band' for about ten minutes, then Bono walked in and blew any chance I had of being in charge." The group settled on the name "Feedback" because it was one of the few technical terms they knew.

In April 1977, Feedback played their first gig for a paying audience at St. Fintan's High School. Shortly after, the band changed their name to "The Hype". Dik Evans, who was older and by this time at college, was becoming the odd man out. The rest of the band was leaning towards the idea of a four-piece ensemble. In March 1978, the group changed their name to "U2".

Steve Averill, a punk rock musician (with the Radiators) and family friend of Clayton's, had suggested six potential names from which the band chose "U2" for its ambiguity and open-ended interpretations, and because it was the name that they disliked the least.
