Automatic advertising?

I'm sometimes fascinated by automatically-generated advertising.

Some examples on recent films I've uploaded.

Here we see a video about standard weights (such as the official troy pound stored at the Royal Society). We get an advertisement for weight loss and dropping dress sizes!

 

A video featuring the famously coiffed Professor Poliakoff - we have a hair product that will "end frizz now."

 

And somewhat mysteriously, this video featuring spy satellites runs with an advertisement espousing the merits of Russian ladies!?
