Nickelodeon is getting into the radio business. The children’s entertainment network has joined forces with Clear Channel Media and Entertainment to create its own station on Clear Channel’s online iHeartRadio. Nick Radio launched Monday with “The Way” singer Ariana Grande — also star of Nick’s “Sam & Cat” — as featured guest DJ, along with another Nickelodeon act, Big Time Rush. With its entry into radio, Nick Radio will provide some competition for Radio Disney, Disney’s terrestrial and Internet radio stations. Like Radio Disney, Nick Radio will feature kid-friendly Top 40 music, stars from its network and celebrity interviews. Besides iHeartRadio, it will also be on Nickelodeon’s own website.
