The industry group Prodiss welcomed the €4 million promised by Culture Minister Fleur Pellerin days after the November 13th attacks on a string of targets including the Bataclan concert venue where 90 people died, but said it was not enough.
“The shock wave (that has hit the sector) needs a medium-term plan,” it said in a statement, “and to minimise the impact we estimate that €50 million will be needed.”
Promoters said ticket sales for concerts in the French capital fell by around 80 percent in the week following the wave of killings, the worst in Paris since World War II.
Fears were also mounting that the cost of extra security measures might lead to more shows being pulled, they said.
Most of the city's major theatres and concert halls reopened over the weekend, with theatres reporting audiences down by more than one third.
Most of the 130 people killed in the jihadist attacks died at a concert by the US group Eagles of Death Metal at the Bataclan in eastern Paris.
Prodiss said it was recommending that its members should contribute to a fund for the victims of the attacks by “giving one euro for each ticket sold in December”, traditionally one of the sector's most profitable periods.
The attacks have already had a serious impact on other cultural events, such as Lyon's Fête des Lumieres which has been scrapped.
Culture Minister Pellerin has promised to put culture “at the centre of the fightback”.
“Terrorists dream of preventing the shows from taking place: we will simply fight them with more shows,” she said.
