I don't know if the flag actually had a name, but I do know that the flag was there to advertise that a performance was being put on. Because theatre was looked down upon by Puritans, the Globe was not allowed to advertise with fliers and such. So the flag was their way of telling people when to come. It was taken down at the end of each performance.

A black flag meant it was a tragedy, a white one meant it was a comedy, and a red one meant it was a history play. If this helps, I've heard it simply referred to as the "playhouse flag."
