This document discusses the rise of social media and its impact on business. It notes that social media has transformed one-way communication into two-way dialogues, democratizing information by allowing people to publish content. The document outlines key statistics on the growth and usage of major social media platforms like Facebook, YouTube, and Twitter. It also discusses how social media is shifting how people discover, read and share news and content. The rise of user-generated content and new business models like blogs are transforming industries like media and photography. The document cautions that while social media provides many free services, users are still "the product being sold" through their personal data.
18. Social media…At its most basic sense, social media is a shift in
how people discover, read and share news, information and
content. It's a fusion of sociology and technology, transforming
monologues (one to many) into dialogues (many to many) and is
the democratization of information, transforming people from
content readers into publishers.
(Wikipedia, May 2009)
39. "A unit of cultural inheritence,
hypothesized as analogous to the
particulate gene, and as naturally
selected by virtue of its
'phenotypic' consequencies on its
own survival and replication in the
cultural environment".Richard Dawkins
(The Selfish Gene 1976)

Most Retweets Happen in the First Hour
We discovered that 92.4% of all retweets happen within the first hour of the original tweet being published, while an additional 1.63% of retweets happen in the second hour, and 0.94% take place in the third hour.
This means that if a tweet is not retweeted in the first hour, it is very likely that it will not be retweeted.
The graph below shows the fraction of tweets from the second hour onwards - the x-axis shows the time in hours since the original tweet, while the vertical axis shows the fraction of retweets within a particular hour. The 92.4% of all retweets, which happen within the first hour, are not displayed in the chart. 1.63% of retweets happen in the second hour, and 0.94% take place in the third hour.

Google automatically scans e-mails to add context-sensitive advertisements to them. Privacy advocates raised concerns that the plan involved scanning their personal, assumed private, e-mails, and that this was a security problem. Allowing e-mail content to be read, even by a computer, raises the risk that the expectation of privacy in e-mail will be reduced. Furthermore, e-mail that non-subscribers choose to send to Gmail accounts is scanned by Gmail as well, even though those senders never agreed to Gmail's terms of service or privacy policy. Google can change its privacy policy unilaterally and Google is technically able to cross-reference cookies across its information-rich product line to make dossiers on individuals. However, most e-mail systems make use of server-side content scanning in order to check for spam.[41][42]
Privacy advocates also regard the lack of disclosed data retention and correlation policies as problematic. Google has the ability to combine information contained in a person's e-mail messages with information from Internet searches. Google has not confirmed how long such information is kept or how it can be used. One of the concerns is that it could be of interest to law enforcement agencies. More than 30 privacy and civil liberties organizations have urged Google to suspend Gmail service until these issues are resolved.[43]
Gmail's privacy policy contains the clause: "residual copies of deleted messages and accounts may take up to 60 days to be deleted from our active servers and may remain in our offline backup systems". Google points out that Gmail adheres to most industry-wide practices. Google has stated that they will "make reasonable efforts to remove deleted information from our systems as quickly as is practical."[44][45]
Google defends its position by citing their use of email-scanning to the user's benefit. Google states that Gmail refrains from displaying ads next to potentially sensitive messages such as those that mention tragedy, catastrophe, or death.[4
