Our post crossed. I have also just remembered that the current laws don't need changing to allow TV stoppages, as follows: "16.3 Suspension of play 16.3.1 When necessitated by circumstances not within the control of the players, the umpire may suspend play for such a period as the umpire may consider necessary. 16.3.2 Under special circumstances the Referee may instruct the umpire to suspend play. 16.3.3 If play is suspended, the existing score shall stand and play shall be resumed from that point. 16.4 Delay in play 16.4.1 Under no circumstances shall play be delayed to enable a player to recover strength or wind. 16.4.2 The umpire shall be the sole judge of any delay in play." To my mind 16.3.1, 16.3.2, and 16.4.2 mean that referees instructions can be handed to umpires (for specific televised tournament) that breaks be taken at specific points for advertisement breaks.
