The book's introduction is insightful and confusing with its many phrases and ideas about how La Revolución came to be Mexico's master narrative. Benjamin writes that many voices (a collective memory) contributed to Mexico's invention as a country and this master narrative is the "shared past" that unifies the members. After reading page 14, I formulated this question, was the revolution the act through which Mexico created itself?

Radio was largely democratized in the Obregon presidency…until a rebellion sprung up against him. Then radio was censored yet again. Even after the revolution, and despite the contextual differences between them, subsequent Mexican presidents used radio in a very similar way to Porfirio Diaz.
