Adwords Keyword Tool Trademark Display
AdWords

I have recently noticed how the team at Google as added trademark ™ display to their keyword tool. To me it’s obvious they are trying to let users know that potential keywords they wish to bid for, may well be trademarked and out of the question.

The other thing I noticed is that not many keywords display the trademark image, even though in fact they are trademarked. Would be interesting to know how long ago this feature was released and if they are just in the process of adding the image to all trademarks.
