Apple was true to its word and has shut down the ad supported free iTunes Radio service. The iPhone and iPad maker warned listeners the service would be shutting down as of January 28th and 29th, and that's exactly what happened.
iTunes Radio lives on in Apple Music, but the free ad supported version is gone.
The streaming Internet stations are still available, but now require an Apple Music subscription. Apple's only free streaming music option now is Beats 1 Radio.
Any stations you made prior to the demise of the ad supported iTunes Radio are still available through your Apple Music subscription, and you can continue to make more stations, too. Trying to make new radio stations, or listen to those you already made, shows the Apple Music signup option instead.
An Apple Music subscription costs US$9.99 a month, or $14.99 for a family, and Apple offers a free three month trial so you can try it out without committing to monthly payments.
