Starting today, you’ll notice a change in the appareance of Google homepages. The company is experimenting to push to all his users a background Image to enrich a bit the user experience.
This feature will be turned on for all users for today and maybe some other hours/day, and them will be available for everyone who select it.
This is basically what Bing has been doing since his launch, and it’s “funny” to see that Google is copying this feature from them.
It would be interesting to understand how much this is slowing the page loads time and if it is going to decrease searches for today
