Based on analysis of Social media chatter around Olympics, we found that Gymnastics is the most popular sport,
followed by cycling, basketball, swimming, equestrian, rowing, archery and judo.
A sample of 43,048 tweets across 27,683 users were
collected between July 29th and July 31st.
Concentration across the US, Europe and Australia.
Popularity of games & sports such as Gymnastics, Swimming, Equestrian, Rowing, Archery and Judo is an
opportunity for corporates to associate their brands with them.

Social Media & The Tale of Two Storms:
Hurricane Sandy & Cyclone Nilam
Social media destinations such as Twitter, Flickr and Facebook were leveraged extensively to
spread information during the Victorian bushfires in Australia in 2009.
Social Media sources have played a key role in disaster reporting, relief and rescue efforts.
We try to explore the role played by government, civic authorities, law and order, general
public, celebrities, activists, journalists and media in the advent of two natural disaster
situations: Hurricane Sandy and Cyclone Nilam.
Sandy & Nilam
Hurricane Sandy was the largest Atlantic hurricane on record, as well as the second costliest
Atlantic hurricane only surpassed by Hurricane Katrina in 2005.
Hurricane Sandy struck in late October 2012. In the United States, Sandy caused severe damage in
New Jersey and New York.
It claimed more than 50 lives, left millions without power and caused over US$ 50 billion in damage
in the United States.
Damages to life and property are spread across Jamaica, Haiti, Dominican Republic, Puerto Rico, Cuba
and The Bahamas.
Cyclone Storm Nilam, which struck India in late October 2012 caused damages across Indian
states such as Tamil Nadu, Andhra Pradesh, Karnataka and Odisha.
According to Semiocast, the United States has 141.8 million Twitter users, and India has over
15 million Twitter users
We collected tweets containing the hashtag #Sandy from Oct 30th until Nov 6th (500,036
tweets from 306,348 users)
We classified #Sandy tweets into four different sets based on the time interval when the tweets
Time Interval 1 has 180,489 Nodes and 232,578 Edges
Time Interval 2 has 60,351 Nodes and 65,842 Edges
Time Interval 3 has 31,033 Nodes and 31,039 Edges
Time Interval 4 has 14,550 Nodes and 13,350 Edges
We also collected about 1500 tweets with the hashtag #Nilam during 31st Oct 2012.
Sandy was 'Instagrammed': Number of #Sandy tweets originating from Instagram ranked fourth, preceded
only by Tweets originating from iPhone, Web and Android and in the case of Nilam, Twitpic scored high.
In disaster scenarios, visual means of message propagation assume prominence.
This is in contrast to our observations with regard to message propagation during the Olympic Games, where Tweets
originating from Instagram scored very low
News Media leveraging Social Media: Journalists and News Media extensively leveraged Social Media for
news propagation and for news amplification. News Media sources and Journalists were the heaviest users
of Social media in the events of both Sandy and Nilam.
Government and officials leveraging Social media: @NYGovCuomo, which is the Official Twitter account
for the Governor of New York State, Mr. Andrew Cuomo consistently emerged as one of the most
important entities. No such trends in the case of Cyclone Sandy where we did not see even a single tweet
from a government official or utility.
Individual Journalists leveraged their Twitter follower base to spread messages faster and they invariably
figured higher up in the network centrality measures as against the twitter accounts of Media houses
which employ them.
Cyclone Nilam saw a low overall coverage in Social Media in India and surrounding affected regions.
Celebrities in the United States were active in social media during Hurricane Sandy as against celebrities in
India who chose to ignore Cyclone Nilam.
Measures of centrality, can show who creates the most connections in the network.
Lists of words frequently used in the network of those who mention #sandy & #nilam can be clustered by
their closest affiliations and most commonly used words
In our case, the Twitter handles of NYC Guv and several leading journalists play this role
This can help trace communities within the network formed by the recurring use of particular words
Using the URLs used in Tweets from the entire network as well as from each of the smaller groups within
the network, we can trace a pattern of interests, values, and engagement that drew the most attention
across the network.
