François Dumontier, the promoter of the Canadian Grand Prix in Montreal, says he is happy with Liberty Media's tenure so far as F1 new commercial right holder.
Dumontier admitted his working relationship with the sport's new managers was quite a departure from the partnership he enjoyed with former F1 supremo Bernie Ecclestone, who "did everything himself".
"When Liberty Media took control, things changed, that's for sure," Dumontier told Quebec's La Presse.
"They have experience in the media, with event management, and they listen to promoters.
"Already they have taken some ideas that I submitted to them and implemented them in other Grands Prix."
While Liberty has nicely picked up the baton, Dumontier insisted its work at the helm of Formula 1 had just begun.
"They inherited an empty shell from Ecclestone and had to set up a whole structure, creating departments, hiring staff," he said.
"For sure everyone is still learning, but the progress is already significant."
