Justin Bieber became the first in a series of music artists to feature in a new digital outdoor campaign by Universal Music and Global Radio's Capital FM. The campaign, which broke last week on Outdoor Plus-owned digital billboards, promotes artists signed to Universal's label and will give commuters real-time updates when they are playing on Capital FM. The ads will run in conjunction with the Capital playlist, rather than on a timed digital out-of-home ad loop, which Global says is the first time this has been done.
