LONDON — The knowledge of results of competitions has driven increased viewership of Olympics coverage on television says Alan Wurtzel, President of Research and Media Development at NBCUniversal, in this video segment provided by NBC.

He says that NBC is besting the Beijing Olympics in primetime in 12 of the past 13 nights, with average viewship of 32.5 million.

Wurtzel says that streams are up to 45 million vs. 14 million for the Beijing Games.  He points to the proliferation of tablets and advanced smart phones.   He says the viewership of these Olympics via digital has skewed to a younger demographic.
