MLA style requires you to cite a television newscast by beginning with the name of the news program (italicized), followed by a period. Then, you state the name of the network which produces the show, followed by a period. Next, MLA style says to identify the call letters of the network, followed by a comma, and then the city, followed by a period. The original airing date then follows, with the day, month (abbreviated if over four letters long) and year listed. Lastly, the medium of publication is stated, followed by a period. For example: ABC World News Tonight (italicized). American Broadcast Network. ABC, New York. 15 Apr. 2013. Television.
MLA allows in-text citations for newscasts to be handled in several different ways. The author may make reference to the newscast within the body of the text. For example, "According to ABC World News Tonight, Barack Obama consistently led in the 2012 presidential polls." The title of the newscast would be in italics. Or, an in-text citation can be referenced by identifying the newscast in parentheses. For example, "President Obama consistently led in the 2012 tracking polls" (ABC World News Tonight). Again, put the title of the newscast in italics.
