Before they became the huge success they are today, an early iteration of the Irish band U2 first performed on television as teenagers over 45 years ago.

On March 2, 1978, a band called The Hype played on RTÉ's young people’s program "Youngline."

Later, that month, however, The Hype changed their name to the one the world has since come to know, U2.

The band originally started when Larry Mullen Jr., who was just a teenager at the time, posted a notice at his school seeking musicians to form a band. The initial group that came together was called "Feedback" and included Bono, The Edge, and several other schoolmates. Over time, the band evolved and changed its name to "The Hype" before finally settling on the name "U2" in 1978.

During the same month as their television debut, they won a talent contest in Limerick. The prize included £500 and a recording session for a demo that would be heard by the record label CBS Ireland.

This was a significant moment for the band and escalated them forward in their career path.

Within four years of forming, they signed up with a record label and released their debut album.

In 1980, U2 released their debut album, "Boy," which received critical acclaim and started gaining them international recognition. The band's success continued to grow with subsequent albums like "War" (1983) and "The Joshua Tree" (1987), which catapulted them to global stardom.

Out of the four members of the rock band, their lead singer Bono (whose real name is Paul Hewson) is probably the most famous. Watching their television performance, you can see the raw talent in all the members, but especially in Bono who dances unconsciously and with an energy that fills the studio.

Today Bono lives in Dalkey, Dublin with his childhood sweetheart Alison Hewson and they have four children together.
