A related query results play. IE, search for “On Demand” and get results with “Comcast” related pages. Readers had been telling me this, but I could not confirm it. Now it appears Mediapost has. This has some interesting business model implications, when you think about it – certainly Google would never do paid inclusion, but this is the kind of thing that might allow for such a move should the company fall into the hands of the Dark Side.
Update: Google PR has given me a statement on this:
Google is testing an automated technique for detecting when an alternate
query might help users find what they are looking for more quickly. For
these searches, which are both commercial and non-commercial in nature,
Google displays one or more alternate queries together with a preview of
their top results.
