May 4th is still a full six months away and Avengers: Infinity War is already breaking records. In fact, at 230 million, Marvel's long-anticipated teaser now holds the title as the most-viewed trailer of all time within the first 24 hours of release, easily surpassing It, which racked up a staggering 197m across the globe in a single day. Word of mouth and a shrewd marketing campaign helped Andy's Muschietti horror gem float to new heights, but when it comes to Avengers: Infinity War, the MCU's impassioned customer base – coupled with the pent-up demand – ensured all eyes were trained on Good Morning America this Wednesday past.
