So according to various sources, alcohol sponsors in Formula 1 might become a thing of the past soon due to political pressure. The sport of course lost tobacco sponsors during the 00's, and alcohol is next. It's not a question of if, but when.
To be honest I've always found it a bit odd to have alcohol sponsors in racing, but especially in recent years the strong 'safe driving' awareness campaigns made up for that. At least that's how I saw that.
It would be quite a hit for Williams if this ban happens anytime soon, right after their Martini deal started. Other teams will be hit by this as well, and seeing how there's enough struggling going on already, it's a bad thing for the sport IMO.
