WordPress has an automatically generated theme that kicks in when someone views a WP blog using a mobile phone or other device.
It overrides whatever theme the blog owner has specified, in order to format the text and images on the blog to make it look better on a mobile device.
Weirdly it also includes advertisements, the content of which the blog owner doesn’t seem to have any control over. They’re randomly inserted in by WordPress/Google Ads, based on the content of the blog entry.
Earlier today a reader who looked at my blog through their iphone sent me this image.
It appears that Google ads is not without a sense of humour.

Who gets any revenue generated by those ads?
I assume you haven’t set them up to use your google adsense aaccount
No idea. Presumably WordPress does. I certainly don’t anyway. I don’t have an adsense account.
