These new Ads are billed as an "opportunity for marketers to reach our hundreds of millions of connected users in a place where they can have meaningful conversations about brands in a highly engaging environment." Makes sense, and so long as the service remains free -- well, we can't really complain. Conversation ads are available for marketers to purchase in 55 markets where Skype is available. Users without Skype credit or subscriptions will see the ads during 1:1 Skype-to-Skype audio calls in Skype for Windows. Skype call quality will remain the same. Ads will be silent, non-expanding and run after we've completed our regular detailed quality checks on one's connection.
Haven't seen one yet? It ought to look a little something like the image above.
