Initially a three-day event, ConnectiCon's popularity led to an expansion in 2014, transforming it into a four-day event from Thursday to Sunday.
The convention includes 24-hour screening rooms of full-length features and episodes of classic and modern science fiction and anime titles and sponsorship by GameStop, which also provides consoles for tournament and casual video gaming.[6]
