How has the media contributed to prejudice and discrimination against Asian Americans? How might these problems be remedied?

In American media and film industry, Asian/Asian American males are portrayed as either unscrupulous, geeks, or feminine. On the other hand, Asian/Asian American women are portrayed as submissive and are often sexualized. In period films, particularly pertaining to World War II, the Vietnam War, and the Korean War, Asians as a whole are seen as aggressors and fascist. These stereotypes existed before the advent of film and television.
In fact, Asian immigrants faced hostile racism during the nineteenth and twentieth centuries. For instance, Chinese immigrants were pressured into living in ghettos during the early days of California's statehood, which eventually became the modern Chinatown. Likewise, Japanese Americans born and raised in the United States were forced to live in internment camps during World War II simply based on their ethnicity. Later on, films such as Sixteen Candles and Breakfast at Tiffany's perpetuated Asian stereotypes.
One of the most effective ways of remedying decades-old stereotypes about a particular culture is by showing the actual lives and perspectives of Asians and Asian Americans. Films and television shows such as the modern remake of Hawaii Five-O and The Walking Dead prominently feature actors/actresses of Asian-descent who don't fit into stereotypes.
As with famous African American actors/actresses--e.g. Will Smith, Denzel Washington, Morgan Freeman, Anthony Mackie, et al.--who have universal appeal, Asian American entertainers can take on roles that don't fit a stereotype. For instance, in Inside Man, Denzel Washington isn't a black detective, but just a New York Police Department detective. Will Smith isn't a black Air Force pilot in Independence Day, but just a soldier who saves the world from aliens. Likewise, Asian Americans should be given opportunities to play general characters.
