Question: Along with the person that The One That Got Away is about, what notable pop artist started his career in adult contemporary radio?

Knowledge 1: The One That Got Away (Katy Perry song)
Originally titled ``In Another Life '', the song was produced by Dr. Luke and Max Martin, both of whom co-wrote it with Perry. It is a midtempo pop song positioned on the piece of E major and has a tempo of 134 beats per minute. Joanna Holcombe from Yahoo! Music noted that the song is about first loves. Leah Greenblatt from Entertainment Weekly, said that the song is`` a midtempo ode to a summer - after - high - school love with whom she recalls sharing Mustang makeout sessions to Radiohead '''. Michael Wood from Spin magazine said that the song is one of the album's quieter cuts and that it recall (s) ``Perry's singer - songwriter days at L.A.'s Hotel Café ''. The song follows the chord progression of E -- G ♯ m -- C ♯ m -- A, and Perry's vocal range spans from B to E. Kitty Empire noticed that Perry's vocal is wistful throughout the song and that the references to June and Johnny Cash were unexpected. Rob Sheffield from Rolling Stone stated that when Perry sings,' I was June, and you were my Johnny Cash, '`` it's understood that she's thinking of the scrubbed - up Hollywood version of June and Johnny, from Walk the Line.'' In 2017, the singer revealed that ``The One That Got Away ''was about Josh Groban. [SEP] Knowledge 2: Adult contemporary music
While most artists became established in other formats before moving to adult contemporary, Michael Bublé and Josh Groban started out as AC artists. Throughout this decade, artists such as Nick Lachey, James Blunt, John Mayer, Bruno Mars, Jason Mraz, Kelly Clarkson, Adele, Clay Aiken and Susan Boyle have become successful thanks to a ballad heavy sound. Much as some hot AC and modern rock artists have crossed over into each other, so too has soft AC crossed with country music in this decade. Country musicians such as Faith Hill, Shania Twain, LeAnn Rimes and Carrie Underwood have had success on both charts.

A notable pattern that developed during the 2000s and 2010s has been for certain pop songs to have lengthy runs on AC charts, even after the songs have fallen off the Hot 100. Adrian Moreira, senior vice president for adult music for RCA Music Group, said, "We've seen a fairly tidal shift in what AC will play". Rather than emphasizing older songs, adult contemporary was playing many of the same songs as top 40 and adult top 40, but only after the hits had become established. An article on MTV's website by Corey Moss describes this trend: "In other words, AC stations are where pop songs go to die a very long death. Or, to optimists, to get a second life."

One big impetus for the development of the AC radio format was that, when rock and roll music first became popular in the mid-1950s, many more conservative radio stations wanted to continue to play current hit songs while shying away from rock. These middle of the road (or "MOR") stations also frequently included older, pre-rock-era adult standards and big band titles to further appeal to adult listeners who had grown up with those songs.
