Google Image Search expansion method reminds me of iTunes

[jon3543]

I just noticed that clicking an image in Google's Image Search now expands just like iTunes 11 when I click an album. This is a great feature and is much preferable to what Google has been doing as long as I can remember. When did Google start doing this? Was there any precedent for this before it showed up in iTunes? None of the programs I use incorporated it before iTunes, and I'm curious who invented it, because I don't remember Google doing it first, and it's exactly like what iTunes introduced in version 11.
