Act II (popcorn)
Act II is a brand of microwave popcorn in North America that is ostensibly based on the look and taste of movie theater popcorn. It is currently made and distributed by Conagra Brands. Act II was preceded in the popcorn market by Act I, an early microwave popcorn that had to be stored in the refrigerator due its real butter content. Act I was introduced in 1981. In 1984, Act II, a shelf stable microwave popcorn was released, becoming the first mass-marketed microwave popcorn.
