    So a couple of days ago I was home searching the internet on my MacBook Pro for certain images to use for a project. Some of the images I found using Google Images took me to Shutterstock.com when I clicked on Visit Page. Later that day, I was home on my iPod Touch playing a game that occasionally puts up ads and lo and behold there is a Shutterstock.com ad showing the types of images I was looking at earlier.

    I was not logged into anything like Google, Yahoo, YouTube, etc. on either system. The only thing in common was the WiFi used. So how does my iPod know what I was doing on the MB Pro?

    Whatever service providing the ads logged your IP address.

    Just how do you sync your devices? Are you on iCloud?

    I do not intentionally sync them. I don't use iCloud.

    I'm on FIOS. Would that service be Verizon?

    No, it would be whatever ad service your game uses getting the info from Google probably.

    You mentioned a Google search that took you to Shutterstock. When you clicked that link Google said, "Hey, [mac_in_tosh's IP address] likes Shutterstock!"

    Then you launched your game, and their ad system (probably Google ads) said, "Hey, it's [mac_in_tosh's IP address] ! Let's serve him up some of those sweet Shutterstock ads. We know he likes those!"

    An oversimplification to be sure, but that's basically what's happening. Nothing to be afraid of.
