In 2013, 'Frozen' became a global juggernaut, grossing $1.28 billion and becoming the highest-grossing animated film at the time. Its success was fueled by the massive popularity of its soundtrack, particularly the song 'Let It Go.' Disney's marketing transitioned from traditional ads to encouraging fan-made 'sing-along' videos on YouTube, which kept the film in the cultural conversation for over a year. It proved that modern animated blockbusters could still dominate the zeitgeist through music and 'emotional resonance' just as effectively as the Disney Renaissance films of the 1990s.
