I think they would be less prominent in the USA if stations weren't required to identify. We have a station in Phoenix that identifies as KISS FM, a brand that originated with KIIS-FM out of LA. But every once in a while they will say their real callsign KZZP.
Same on TV, when I was a kid our PBS stations always went by KAET, later on they went by the channel number Eight. Now that people might not even be watching on a channel (streaming) they just go by Arizona PBS, but every once in a while they show their station callsign and the call sign of all the translators (stations that transmit identical signal in other parts of the state)
