I know that Google AdWords allows and disallows use of competitive trademark terms in AdWords however I'm wondering if there have been any recent updates.
For example, can Ford buy General Motors type trademarked / branded keywords or is that against the rules?
One cannot use Ford in an adwords ad purchased by GM to sell GM products, right?
Is there a clear and RECENT statement somewhere on the web that clarifies all this?
I also know there was a recent 2010 ruling in Europe that seemed to turn this all on its head - does that also apply to US advertisers?
Thanks!
