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.
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?
