Japan's win over USA in the Women's World Cup final set a record 7,196 tweets per second (TPS). It was followed closely by the 7,196 TPS generated by the Brazil vs Paraguay in the closing minutes on the same day.
In comparison, the previous record set on New Years Eve in Japan in 2010 produced 6,939 TPS at its peak. Kate Middleton and Prince William's nuptials in April saw 3,966 TPS. Other huge volume events were the 2011 Super Bowl and this year's devastating earthquake and tsunami in Japan.
These records will probably be eclipsed soon enough with the fact that 600,000 new users sign up daily for Twitter. It is interesting to note that the 2010 Men's World Cup finals did not figure in these records even though that match had its share of non-football related dramatic moments.
