A Compendium of Rio 2016 Olympics Stats

Snapchat viewing 
"Almost 50 million people have watched the Olympic Games on Snapchat so far, as broadcasters including NBC and the BBC use the app to reach a millennial audience.
Nearly one in three daily Snapchat users has viewed the clips in Live Stories, showing that the app could challenge other social sites such as Facebook and Twitter for dominance in live events.
The LA-based start-up partnered with broadcasters in seven countries including the US, the UK and Brazil to show stories that include footage from the games and from the crowds in the last 24 hours.
In the first seven days to last Thursday, 49 million unique visitors viewed Olympics content on Snapchat, almost a third of the 150 million daily active users of the app."

Over 5bn viewers globally
"Heading up this vast operation is Yannis Exarchos, who runs Olympic Broadcast Services on behalf of the International Olympic Committee, and says that the Rio Games saw internet and on-line viewership as big a factor as [conventional] television. He added that social media helped drive this digital audience to Rio, and took this year’s viewing numbers to a record 5 billion users. Within the first 4 days of competition more people had watched Olympic activity on second screens than during the whole London Games of 2012.
Within 10 days of the start of the Rio Games the on-line streaming numbers had passed the two previous Olympics (London and Sochi). Ratings agency Nielsen said more than 2 billion minutes (33 million hours) were consumed in the US alone in the first 10 days of competition.
Exarchos also said that this year’s experimental Virtual Reality (VR) programming was also a huge hit with viewers, and by Tokyo in 2020 VR and 360-degree material could be a very important factor for consumers and where viewers are at the centre of the action right alongside the athletes."

NBC's US TV viewing fell 15% vs London 2012
"While Mr. Burke's nightmare scenario didn't play out to the letter, the final Nielsen numbers were fairly grim. Through the 17 nights of ceremonies and competition, NBC averaged 26 million viewers and a 14.9 household rating, which marked a 15% decline from the 2012 Summer Games' draw of 31.1 million viewers and a 17.5 rating. (Rio's ratings reflect NBC's Total Audience Delivery, a metric that blends broadcast and cable prime-time deliveries with streaming data.)
More importantly, NBC missed its ratings guarantees by 3.1 points, or 17%, a result that found the network working overtime to make its advertisers whole through Sunday's closing ceremony. Media buyers last week said they were satisfied with NBC's make-good efforts but said that they expected some high-end clients to receive complimentary units in the network's Sunday and Thursday night football packages as a goodwill gesture. (UPDATE: NBC said that all of its Olympics advertisers were made whole within the Games themselves and that the network would not be offering so-called audience deficiency units in the fall."

NBCU on TV and Snapchat
"NBCUniversal decided to turn over the keys to its Snapchat account to BuzzFeed for the Olympics. The move seems to have paid off to the tune of 35 million viewers over two weeks.
In April, the media giant announced a partnership with Snapchat, under which it would distribute Olympics-related content on the media and messaging app. The content was available in two ways: a pop-up Snapchat Discover channel and multiple daily Live Stories. Across both, NBCU totaled 2.2 billion views and 230 million minutes of consumption, the company said.
With the Discover channel, NBCU gave near-total editorial control to 12 BuzzFeed video producers it had invited down to Rio (NBCUniversal invested $200 million in BuzzFeed last year). “We would talk to them every morning — what we were focusing on and the stories that were emerging, and there would be some coordination that way,” said Gary Zenkel, president of strategy and operations for NBC Sports Group and president of NBC Olympics. “But we did not want to impair their ability to exercise and flex their creative muscles for that day’s edition."

7.5bn video streams watched in China
"Shanghai-based Alisports, a division of e-commerce giant Alibaba Group, said it saw similar success streaming the Olympics in China through a partnership with online video hub Youku Tudou.
A total of 7.5 billion streams were watched by Olympics fans in China, according to newly released figures from Alisports.
Alisports last month had announced a licensing agreement with Chinese state-owned CCTV to stream the Rio Olympics via Youku, which is also owned by Alibaba, albeit with a 30-minute delay to CCTV’s own broadcast. About 380 million viewers logged on to watch, Alisports said. That’s almost half the size of the traditional television audience of 793 million claimed by CCTV."
