ESPN Megacast

ESPN Megacast, formerly known as ESPN Full Circle, is a multi-network simulcast of a single sporting event across multiple ESPN networks and services—with each feed providing a different version of the telecast making use of different features, functions or perspectives. These simulcasts typically involve ESPN's linear television channels and internet streaming platforms, and may occasionally incorporate other Walt Disney Television networks at once.

ESPN Full Circle debuted with ESPN Full Circle: North Carolina at Duke on March 4, 2006, on the one-year anniversary of ESPNU. The game was the North Carolina Tar Heels at the Duke Blue Devils in college basketball. Five further Full Circle broadcasts were produced (one NBA playoff game, one NASCAR race and three more college basketball games) before the format was discontinued in 2007.

After a seven-year hiatus, full-circle broadcasts resumed under the Megacast branding in 2014. To date, the feature has primarily been used for the College Football Playoff and National Championship. ESPN has occasionally provided smaller-scale slates of alternate feeds during other broadcasts, although these have not always used the "Megacast" branding.
