[Air-L] Maybe Off-topic: Ageism and Media

[NQ]

Hello, 
This may be a bit off-topic, but I was wondering if anyone on this list
knows of an expert/researcher who's looked at ageism in the media, more
specifically negative stereotypes of older people in media representations,
including countries other than the US.  If so, could you please forward some
names to me?  I am looking for a speaker to propose for a US event in New
York.
Thanks,
Nelida
