He had served as an IOC member since 1994, and on Coordination Commissions for the last five Summer Olympics, including as vice-chair for Tokyo 2020.

He was a member of the Paris 2024 Coordination Commission from 2017.

Other IOC Commissions of which Gilady was a member include International Relations from 2014 to 2015, as well as Communications, and Public Affairs and Social Development through Sport, both from 2015 until his death.

Gilady's background was in sports broadcasting, having began his career as a journalist in Israel in 1964.

He went on to become a sports commentator for NBC Sports and hold leadership roles with the American Olympic broadcasting rights holder.

This included stints as head of sports in 1975, special operations in 1977 and vice-president from 1981 until 1996, after which he became senior vice-president.

He was also the founder, President and chief executive of Keshet Broadcasting Ltd in Israel from 1993 until 1999, reassuming the Presidency from 2005 until 2017.

His work broadcasting the Olympic Games earned him seven Emmy Academy Awards.

Gilady's IOC involvement began as a member of the Radio and Television Commission in 1984, serving on the body until 2015.

The IOC plans to fly the Olympic flag at Olympic House in Lausanne at half-mast for three days, and Bach was among those who paid tribute to Gilady.

"With the passing of Alex Gilady we are losing a pioneer of the modern Olympic Movement, particularly in regard to broadcasting, but also far beyond that," the IOC President said.

"He has always stood up for the Olympic values, often when sometimes the situation was not easy for him.

"We all appreciated his open personality and his frank way of speaking even if we did not always agree, because with Alex we always knew that he was speaking from the heart. 

"He was always a genuine person.

"In Alex I have lost a dear friend who advised, inspired and supported me in many respects.

"In fact, it was Alex who convinced me in 1996 to run for a seat on the Executive Board for the first time.

"Since then, he has always been at my side.

"Above all, he was a great man and a wonderful friend."

Australian Olympic Committee President John Coates, the chair of the Tokyo 2020 Coordination Commission, offered his memories of his "great friend".

"IOC President Thomas Bach appointed us both chair and deputy chair of the Tokyo 2020 Coordination Commission," Coates said.

"Alex was by my side every step of the way over our eight years preparation for the postponed Games.

"His advice was invaluable.

"As a former vice-president of NBC Sports, his knowledge of Olympic broadcasting was extraordinary.

"For Tokyo 2020, he always ensured Yiannis Exarchos, chief executive of Olympic Broadcast Services and the global broadcasters were always consulted on the big relevant decisions.

"Over our eight years working together Alex became more than a great friend and advisor and I will miss him immensely."

In 2017, Gilady faced allegations of sexual harassment in the 1990s by two female journalists - Oshrat Kotler, a broadcaster at Channel 10 Israel, and Neri Livne, a journalist at the Haaretz newspaper.

He temporarily stood aside from his position as head of Keshet Broadcasting Group to fight the claims against him, but did not relinquish any of his IOC positions.

Livne had accused Gilady of exposing himself and propositioning her during a work meeting relating to the 76-year-old's role as President of Keshet Broadcasting Group in 1999.

Kotler claimed to have received an "indecent proposal" from Gilady.

Gilady launched a lawsuit against his accusers in 2018, but later settled the cases.

"What started as big storm is turn to nothing," Gilady told insidethegames after reaching a settlement.

Gilady also held broadcasting-related roles with International Federations.

He was chair of the International Association of Athletics Federation's - now World Athletics - Television Commission from 1985 until 2008, after which he became honorary chairman for life, and headed the International Basketball Federation's TV Council from 2004 until 2019.
