They used to have these to get people hyped up for the shows.

Also yes, Gideon was created by Barry so i believe he plays some sort of role in the Time Masters creation. However probably not a big one besides making sure everyone has A.I on their journeys so that their Gideon tells them to not endanger the timeline. That way every time master has their own Team Flash.
