WHEN ANTITRUST MET FACEBOOK
Christopher S. Yoo'
INTRODUCTION
Social networks are among the hottest phenomena on the Internet. Fa-
cebook eclipsed Google as the most visited website in both 2010 and 2011.'
Moreover, according to Nielsen estimates, as of the end of 2011 the average
American spent nearly seven hours per month on Facebook, which is more
time than they spent on Google, Yahoo!, YouTube, Microsoft, and Wikipe-
dia combined.2 LinkedIn's May          19, 2011 initial public offering (IPO)
surpassed expectations, placing the value of the company at nearly $9 bil-
lion,' and approximately a year later, its stock price had risen another 20
percent.' Facebook followed suit a year later with an IPO that placed the
value of the company at over $100 billion.' Other social networking sites
remain hot properties, and other Internet companies are struggling to catch
up.
In what may be considered a rite of passage previously faced by such
high-tech giants as IBM, AT&T, Microsoft, and most recently Google, so-
cial networking companies are now facing increasing scrutiny under the
antitrust laws.' Early private antitrust cases have begun to appear.'

achieved a $100-plus billion market value with its May 18, 2012 IP0, but noting that the lack of a
big 'pop' for the stock during initial trading suggests this valuation may fizzle over time).
