A WebmasterWorld thread has someone noticing that Google is showing rich snippets under a site but those rich snippets are coming from a different set of sites, not from the listed site's source code.
The search result is for [coldplay], a popular band. The result loads their home page and then what appears to be event rich snippets below the search listing. Here is a picture:
As you can see, the event information is coming from third party sites such as ticketmaster.com, vividseats.com, and others. How did they manage to get listed under a web page for such a popular brand? Is this specifically being pulled from these third party site's rich snippets data? I guess these sites are more trusted than others?
I assume this happens with other rich snippets?
