I noticed an interesting ad while searching wired - search for
"brammo" or
"brammo empulse".
"Ads by Google .. Zero Motorcycles-Zero S
www.zeromotorcycles.com/ Fully Electric Street Motorcycle Fastest-Lightest-Quietest-Cool"
That's .. not a Brammo Empulse.
Oddly, a search in google itself reveals NO ads on the top / right for those two searches. Most other searches on google have ads associated with them. Try a
Bing search, or
yahoo.
There's nothing illegal here. Judges in both the US and Europe
have ruled that buying up search terms using a competitors trademarked name is legal. Whoever is responsible - whether Zero or a third party advertising contractor - is playing hardball though.
