I just walked into the office to see my wife's laptop open, internet page on display, and a HUGE display ad for Long Tall Sally, the clothing shop for taller and larger women.

Now, given that my wife is tech savvy, she will know how and why an ad will display. She'll also know it's not been her activity, but has come from within our house/IP address.

I have to say, it's caught me by surprise as I generally dont see ads going across both devices AND Google accounts.
