An advertising campaign for John Campbell's new show on Radio New Zealand had to be altered after using a trademarked phrase.
The line "Radio with Pictures," which featured prominently on two Auckland billboards, on air and across social media channels, had already been trademarked by content creation company Tandem in 2015.
In a detailed blog, the Christchurch business said they were willing to "defend and protect" their territory.
"I'm a big fan of John Campbell and RNZ but unfortunately our company registered the name for our new multimedia digital sales package for use on radio and online last year," Tandem managing director Dave Dunlay said.
"Radio with Pictures is an exciting new package our business is offering and consequently we had to defend and protect the trademarked name."
