Glendale Life: Glendale Life is an Armenian-American reality television series that airs on USArmenia TV.  The series follows a group of Armenian friends living in Glendale, California and the surrounding communities of Los Angeles.  The first season starred Anna Victoria "AV" DerParseghian, Lucy Samuelian, Veha Tarious, Arabo (Elcid) Sarkisian, Arman Mardigian, Lola Sarkisyan, Edgar Rostomyan, and Nadia (Nadejda) Hovhannisyan.  The show received some backlash from members of the Armenian community for allegedly stereotyping.  However, the show draws heavily from American "reality" shows featuring singles and, with its predominant themes of sexuality and materialism, has little to do with the predominantly family-oriented lives of the vast majority of Armenian-Americans in the area.  It could thus be viewed more as an attempt to impose American stereotypes upon Armenians than of Armenian stereotypes, which in fact tend toward seeing the nationality as sexually conservative, hard-working, and business-minded.  The first season premiered on September 15, 2014 and ended on December 29, with the 2 reunion episodes airing on December 30, and 31, respectively.
