> I mean, Google MUST have lost some revenue.

Maybe an employee developed it in his 20% of time and they put it up because "why not?".

I think he means lost revenue due to people not searching and clicking on ads as much.

Of course, it also drove a lot of people to google to check it out, hard to measure the good feelings towards google due to that. The images they display really does generate a lot of good feeling, for a tiny bit of work for google.
