Audible sells digital audiobooks, radio and TV programs, and audio versions of magazines and newspapers.

To drive new memberships, Audible ran a multichannel campaign that offered a free 30-day trial plus free audio book. StarStar Mobile boosted the campaign by powering **AUDIBLE, which callers dialed to redeem Audible's promotion.

Audible included **AUDIBLE as an easy-to-remember CTA in television and radio ads.
