At the start of the 1990s Canadian rock took a distinctive turn. Just as artists from the 1970s competed with disco, artists from the 1990s were competing with Canadian hip hop and American hip hop on the Video and Radio charts. Glam metal and arena rock had lost its position as Hip hop, alternative rock and grunge became the new sound of the next generation. Canadian publications devoted to Canadian rock and pop music, either exclusively or in tandem with more general editorial content directed to young readers, was expanding rapidly in the 90s. It was a decade of incredible nationalism, at least as far as English-Canadian music was concerned. The 1971 CRTC rules (25% Canadian content on Canadian radio, increased to 30 per cent in the 1980s) finally came into full effect and by the end of the decade, radio stations would have to play 35% Canadian content. This led to an explosion of Canadian bands ruling the Canadian airwaves unlike any era before. This includes The Headstones, The Tea Party, Matthew Good Band, Moist, Sloan, The Gandharvas, Change of Heart, Skydiggers, Eric's Trip, Limblifter, Salmonblaster, supergarage, Shyne Factory, Doughboys, Crash Test Dummies, The Lowest of the Low, 13 Engines, Odds, I Mother Earth, Big Sugar, Glueleg, Age of Electric, Rymes with Orange, Strapping Young Lad, Bif Naked, Rheostatics, The Watchmen, Moxy Früvous, Rusty, Our Lady Peace, The Philosopher Kings, Junkhouse, Wide Mouth Mason, Pure, Thrush Hermit, cub, The Killjoys, Sandbox, Treble Charger, Big Wreck, The Weakerthans, Propagandhi and The Planet Smashers.
