Google accepting ad from 3rd party

[temi]

Got this interesting message from Google yesterday:

We're happy to announce that the Google content network now
accepts display ads served from qualified third-party vendors.
During this initial release, only ads in English are eligible,
although we look forward to offering more options in the future.

I wonder who the 3rd party they are talking about are, Yahoo perhaps?

Hmm.. sound interesting.. Yeah I was also thinking.. maybe it's Yahoo
