An ISP in Canada is experimenting with adding content to user pages to get their attention and provide them with information. CNET has the particulars on this approach from Rogers, which acknowledged it is experimenting with splicing content onto existing websites.

Although I have not seen this technique used by my ISP Charter Communications, they routinely have what I think is a sneaky practice of pushing out Charter advertising listings during some searches that are formed incorrectly.

Frankly this is an area where Microsoft has not been very aggressive at all, owning as they do the browser used by some 75%+ of the surfing market. I’ve been amazed at how MS has chosen not to push the legal limits by doing more to default search and services to MS properties.
