It's a mouthful for announcers to get their tongues around the dual branding that still exists on B105, 2Day and Fox, since the launch of the Hit brand for SCA's Today Network.
"B105 Hit 105.3" is clumsy no matter how carefully you say it, and so is the reversal "Hit 105.3 B105."
But announcers in Brisbane may not have to worry about the dual branding too much longer.
