Search in Google for [hanukkah] or [chanukah] and you will see Jewish stars decorations across the top of the Google search bar.
Here is a picture:

Google does this every year, but normally it separates the AdWords ads from the organic listings. This year, they have it running across the top.
I expect the same thing to happen soon for searches on [christmas] and [kwanzaa], with their respective decorations, as they do every year.
Why Hanukkah first? Well, Hanukkah is this Tuesday.

I think blue stars would be in better taste on Hanukkah, or anything but yellow.

Do they do this for Eid?
