Super Bowl LVIII set to break TV audience records

Sunday's Super Bowl looks set to be the most watched NFL game ever around the world with a record-breaking US TV audience expected to tune in.

The highly-anticipated match up between the San Francisco 49ers and the Kansas City Chiefs will be shown in 190 countries and is getting a boost from the US State Department, which is hosting watch parties in more than 30 overseas locations.

"Basically the entire world is getting access to the Super Bowl," NFL Executive Vice President Peter O'Reilly said.

Sports diplomacy is reaching new heights with US embassies hosting watch parties everywhere from Chile and Cyprus to Rwanda, Turkmenistan and beyond.

The NFL on Friday continued to push into new markets by announcing it will play a first regular season game in Spain in 2025 at soccer side Real Madrid's Santiago Bernabeu stadium.

The league previously announced that it will also venture into South America for the first time next season with a game in Sao Paulo, Brazil.

Sao Paulo will be one of five international games next season along with three in London and one in Munich.

NFL clubs have agreed to hold up to eight overseas games in 2025.
