And because streaming services now release episodes at the same hour, the definition has stretched to include simultaneous digital premieres.
Frequently asked questions

1) Confirm the broadcast time in all relevant time zones. 2) Test promos with focus groups. 3) Review rating trends for comparable genres. 4) Use a scheduling checklist before finalizing the grid.
