The production company of the ARD documentary "Death and Games - Munich '72" paid one of the Palestinian hostage-takers interviewed after the shooting almost 2,000 euros for usage rights, among other things.
The RBB confirmed this on Friday.
The magazine "Focus" had previously reported on it.
As a result, the 69-year-old Mohammed Safady received the fee.
In the four-part ARD documentary, he boasted about the attack on the Israeli Olympic team and the killing of eleven athletes and a Bavarian police officer.
He has no regrets.
At any time he would take on a new order to murder Jews.
Relatives of the murdered Israeli athletes reacted with horror, as "Focus" reports.
The spokeswoman for the victims' families, Ankie Spitzer, whose husband André was tied up in the helicopter and was allegedly shot by Mohamed Safady, told the magazine: "For me it is a media scandal from ARD that killers are paid money for their inhuman statements .”
The RBB, which took over the management of the production with SWR, announced that the ARD broadcasters involved had to ensure that no interview fees were paid to the two surviving assassins.
The producer Gunnar Dedio from Looksfilm has confirmed this several times - also in writing.
Only the expenses customary in the industry, in particular for security precautions during the interview with one of the assassins, were assumed by the production.
A few months after the shooting, Dedio agreed on a temporary exclusivity with one of the hostage-takers.
In terms of content, these relate to the rights of use both for the interview and for the documents and photos provided, the broadcaster explained.
The production company paid them 2,000 US dollars (around 2,000 euros).
"Our editors have not been informed about this by the producer - the confirmed Looksfilm," said RBB.
Looksfilm declined to comment on the allegations when asked on Friday.
"Death and Games - Munich '72" is a four-part documentary about the Olympic attack on September 5, 1972, which ARD broadcast 50 years after the attack in September.
The Olympic assassin Mohammed Safady also has his say.
Looksfilm produced the documentary in co-production with RBB, SWR and BR for ARD in cooperation with France Télévisions and the Dutch public broadcaster VPRO.
In the attack on the Israeli athletes in their accommodation in the Olympic Village, the Palestinian assassins killed two athletes and took nine hostage.
All Israeli hostages, one policeman and five of the eight hostage-takers were killed in a failed rescue attempt at Fürstenfeldbruck airfield that night.
