It is more and more common to use the internet to do research. While citing an article from the internet, you include the first thing that occurs in the works cited entry for that article. This can be the name of an author, the name of an article, a website name, or a film name. In this case, since the works cited entry starts with the article name, that is also what needs to be included in our parenthetical citation.
