Kerrang! began as a one-time issue in 1981 focusing on heavy metal music like AC/DC. Due to high demand, it became a monthly magazine published by Bauer Media. Originally focusing on thrash metal and glam rock, Kerrang! adapted to grunge in the 1990s and nu metal in the 2000s. When nu metal declined, Kerrang! shifted to emo and metalcore, receiving criticism for moving with trends. Now Kerrang! covers various rock genres to appeal broadly without tension between groups, though some criticize its promotion of bands like Black Veil Brides.
