With the Puerto Rican diaspora of the 1940s, Puerto Rican literature was greatly influenced by a phenomenon known as the Nuyorican Movement. Puerto Rican literature continued to flourish and many Puerto Ricans have since distinguished themselves as authors, journalists, poets, novelists, playwrights, essayists, and screenwriters. The influence of Puerto Rican literature has transcended the boundaries of the island to the United States and the rest of the world. Over the past fifty years, significant writers include Ed Vega (Omaha Bigelow), Miguel Piñero (Short Eyes), Piri Thomas (Down These Mean Streets), Giannina Braschi (Yo-Yo Boing!), Rosario Ferrer (Eccentric Neighborhoods). and Esmeralda Santiago ("When I was Puerto Rican)."
