Watch the piece about our Facebook Smile research on ABC's World Tonight with Diane Sawyer: It was the "finale" of the program

Diane talked about the research repeatedly during the program...and they closed the broadcast with this nicely-executed piece. It's "light" (i.e., it does not really get into the complexity of our findings), but fun. Thanks to Diane--and to Cecilia Vega who produced and narrated the segment.
