Twitter connected last night on its hashtag Hail Mary .
The social service set a new record for gameday activity during Super Bowl XLVI --12,233 tweets per second  at the end of the game. The second highest rate came during Madonna's Caligula-inspired halftime extravaganza: 10,245.
Compare that with past spikes. The Bin Laden raid topped out at 5,106 tweets per second and held steady at 4,000 sustained tweets. The MTV Video Music Awards topped out 2011  with 8,868. The biggest ever spike? the December 13, 2011 television broadcast in Japan of Hayao Miyazaki's animated feature, Castle in the Sky , which got 25,088 per second .
More interestingly, as Twitter  continues to blow up during giant international news or pop culture events, TV viewership for the Super Bowl was stagnant. Super Bowl XLVI averaged a 47.8 overnight household rating/78 share on NBC, Variety reports . That's slightly down from last year's 47.9 rating, a tie for the best ever.
The numbers would seem to justify the new race to rule the second screen .
