Kerrang! is a British rock music magazine that has been published since 1981. It was originally a supplement in the Sounds newspaper and focused on hard rock and heavy metal genres. AC/DC appeared on the first cover. The magazine remains the top-selling music weekly in the UK. Kerrang! targets 16-25 year old rock music fans by featuring their favorite bands prominently and offering free posters and CDs to attract buyers. It keeps consumers informed about bands, concerts, and new music releases. Looking ahead, the magazine plans to create an online subscription version and app to capitalize on smartphone usage while continuing to offer freebies with the print edition.
