[Athen] correct terminology -- audio description or video description

[Jennifer Sutton]

Greetings, ATHEN list folks (along with a few others I've bcc-ed):


I'm sorting through my resources, and I'm confused about what the 
correct term is for adding audio to videos to help explain visual 
elements for blind people.


I know that we initially called it "audio description," but I had in 
mind that the term was shifting to "video description" since that 
describes better what it is, at least to a degree.


At the same time, I still see current articles and sites calling it 
"audio description."


Does anyone have the definitive "scoop?"


I'd welcome links/citations in support of responses.


Is this, perhaps, one of these situations where we might *like* the term 
to change, but the term "audio description" is so prevalent that 
progress is slow?


Are there legal ramifications, i.e. maybe some state laws refer to it in 
different ways?


Thanks in advance. I'm updating some things, and I'd like to get it right.


If it doesn't matter/they're now considered simply synonymous, I'd like 
to know that, too.


Best,

Jennifer
