Final answer:
The 1970s saw a shift in the portrayal of Asian men in media, greatly influenced by actors like Bruce Lee, who introduced a strong, skillful image contrasting with previous stereotypes.
Step-by-step explanation:
During the 1970s, the image of Asian men in media began to change, which coincided with periods of increasing immigration from Asia and rising national attention. Previous stereotypes in film and television often depicted Asian men according to narrow, caricatured roles, but this began to shift as certain Asian actors started to take on more diverse and leading roles. For example, actors like Bruce Lee broke away from traditional stereotypes and presented a new image of Asian men as strong, charismatic, and skilled, particularly in action films genres. These changes also reflected broader cultural and societal shifts during the time regarding race relations and media representation. However, it's essential to acknowledge that despite some progress, stereotypical portrayals continued for some time and there is ongoing dialogue about the visibility and representation of Asian identities in media.
