MNN, the Monster News Network, is a CNN style broadcasting channel in Sesame Street Stays Up Late!. The network's motto is "We cover the globe," as exemplified by two monsters who serve as MNN's logo. The network offers a special global broadcast on New Year's Eve. Elmo is the chief anchor in the United States of America, with Cookie Monster as science reporter, Prairie Dawn as special Sesame Street commentator ("I'm not really a monster but it is a job in communications"), and a slew of special international correspondents, including Cousin Pepe and Rosita, Elmo-noske, Moishe Oofnik, Samson, and Max Mekker.
