When the House passed the Affordable Care Act in 2010, TPM topped out at 4,022.

The number of tweets puts the Supreme Court event on par with a sports event. In May, 32,000 tweets per minute were sent at one point during the Champions League Final of European soccer.
But it doesn't come close to the overall record. In 2011, when singer Beyonce announced her pregnancy on live TV, it set a record of 8,868 tweets per second (TPS), at that time the most TPS ever recorded for a single event. Japan's New Year's celebration this year beat it with 16,000 TPS.
Some of the most memorable tweets sent Thursday were from Sarah Palin (who rhymed), DNC staffers (who got a little "excited"), and the lawmakers who were fooled by CNN initially misreporting the decision.
