Two moments of history at one time. Great Britain won their first 4x100m relay gold at World Athletics Championships. Silver twice, but gold for first time. The last time they had grabbed the top podium was in Olympics 2004 at Athens when they breezed past the then great Maurice Greene by one-hundreth of a second. Also, this was Jamaica's first defeat in this event since their shot to dominance in 2008. Not only did they miss out on their gold medal, but they failed to finish the race.
