What a fantastic Rugby World Cup it has been!
Here is today's idiom, " go live ".
This means that something becomes operational. It can also mean to broadcast live from the scene of an event.
Example 1
Our new YouTube channel will go live from tomorrow morning.
Example 2
We sent our reporter down to the Yokohama stadium to interview some of the rugby players. We will go live with those interviews, right after the game is finished.
