popular TV show + new Southeast Asian character + bone marrow donation info
This is definitely building on "House, Anyone?" (Inspiration 172) and "Jai Ho! The Bollywood influence" (Inspiration 191). I know Glee has a huge following and they often bring awareness to different issues, such as STD awareness or responsible drinking.
I'm currently working in the Philippines and I noticed when they had a Filipino actress guest star on the show, the number of Filipino viewers went up drastically. Maybe a mainstream TV show could get a popular Southeast Asian actor/actress to guest star, and include information/plot about bone marrow donation. It could end with a brief on how one can take action.
A popular TV show, like Glee, could be the perfect media spot to educate and encourage more people to donate.
