National Olympic broadcaster Seven is counting on a sentiment boost from vaccine hopes as well as from the organisers' confidence that the Tokyo Games will go ahead to make up for the revenue it lost – about one-fifth in total – from pandemic-hit sponsors unable to continue their financial support of next year's Games broadcasts.

Seven, which has local rights to the summer Olympics, now due to begin on July 23, and the Paralympics the following month, on Friday confirmed a sponsor for next year's Games, boosting its committed sponsorship to 85 per cent of the total. Sponsors accounting for about 20 per cent of Seven's partnership revenue earlier opted not to continue for an extra year due to the postponement.
