Marvel Studios' clever live five-hour-plus announcement of the cast of Avengers: Doomsday was their biggest livestream, bigger than any premiere red carpet, pulling in 275M digital views we're told and 3.1M social mentions. The livestream began yesterday at 8AM PST and lasted for 5 hours and 27 minutes.
That number is also more than 5x the social volume of the Deadpool & Wolverine Super Bowl trailer (currently the most viewed trailer of all time) from last year.
More deets I'm told: hour over hour the audience grew to what is the most view cross platform livestream stunt.
