The monolithic, three-story media wall in the lobby of Wallis Annenberg Hall serves as an easy visual metaphor: Its towering presence always conveys that you’re at the center of something. When big news is breaking, USC Annenberg students, faculty and staff know they can gather to witness it here — especially if that news is about national politics. During the 2016 election season, all three presidential debates were shown live on the media wall, with students packed onto three floors engaging with faculty in post-debate discussion.
