Google: uncomfortably close to the edge

Google has had a transformative effect on the world. It reminds me of Dieter Rams on the concept of design had said something to the effect of good design being invisible – once you see the product you couldn’t imagine things exist any other way.

That’s a really good description of the web with Google. In the markets where it operates (with the exceptions of Czech Republic, South Korea, Japan and Russia) it’s a monopoly. Different regulatory authorities are investigating them for leveraging their monopoly into market domination in other categories.

With SERP (Search Engine Results Page) like this one above, I am not surprised that antitrust authorities are gaining an upper hand. This Urban Dictionary integration seems to cross the boundary from being useful to feature bundling. It deprives Urban Dictionary of an opportunity to put ad inventory in front of its audience.

It would be interesting to see if Google got into some sort of content agreement with Urban Dictionary or have just gone ahead and done this?
