Britain's biggest gambling companies have agreed to a "whistle-to-whistle" advertising ban.
It follows political pressure about the amount of betting advertising on TV.
"We believe that this is itself a watershed moment as we strive to provide the ever safer gambling environment which gambling consumers and the wider public expect, and which is so important to the future success and sustainability of our industry," IGRG chair John Hagan said.
"Today the gambling industry is responding positively to public concerns about the amount of gambling advertising on television before the watershed."
No betting adverts will now be shown during live sport coverage before 21:00 in the UK from five minutes before the event begins until five minutes after it finishes
