Once Upon a Time is an American fairy tale drama television series that premiered on Sunday October 23, 2011, on ABC. New episodes air Sunday nights at 8:00 pm ET/7:00 pm CT. The series cleverly plots between two worlds: fairytale world and real world. From the inventive minds of Lost executive producers Adam Horowitz and Edward Kitsis comes a bold new imagining of the world, where fairy tales and the modern-day are about to collide. And they all lived happily ever after – or so everyone was led to believe.
