AD AGE - Feb 14 - Online Dating is clearly big business: In the U.S. alone, internet dating is a $1.3 billion market, and PlentyofFish alone had 122M visits in January, according to Experian. The number of people scrambling for romance via online dating starts growing in November and peaks at Valentine's Day. "People realize sitting around the Thanksgiving table with their family and think, 'Hey, I don't have my other half' or 'My sister's married and I'm not,' so it's a cyclical event," said Mark Brooks, dating industry consultant at OnlinePersonalsWatch.com. The sector has also seen some matchmaking of its own: Just a few weeks ago, Match.com purchased OKCupid. Mr. Brooks said that Match.com has been acting like the Google of the dating world and gobbling up smaller dating sites at a quick pace.
