The ads shown above, below and in the box to the right of nearly every email message on desktops are the predecessors of those email-like ads that rolled out with the new tabbed inbox.</p><p>Users may confuse the three ads for AdSense ads that also appear in Gmail, but they are in fact part of Google's Gmail Sponsored Promotions beta.
