A "Cinematic Universe" refers to a series of interconnected films and television shows that share common characters, settings, and storylines. This concept allows for a cohesive narrative across multiple media, creating a larger world that fans can explore. Popular examples include the Marvel Cinematic Universe and the DC Extended Universe. In a Cinematic Universe, characters can appear in different films, and their stories can intertwine, leading to crossover events. This approach encourages audience engagement and loyalty, as viewers become invested in the overarching plot and character development across various installments.
