The war is officially declared between Microsoft Office 365 and Gmail. The IT giant is openly attacking the "Google mailman" in a satirical video.
Contextual advertising
In this rather funny video, Microsoft criticizes the intrusiveness of Gmail. The "Gmail Man" (known as “Gmail mailman”) will read your emails to propose advertisements in connection with your interests, the famous contextualized advertising.
What is the truth? Two sides are passing the buck to each other. Microsoft assures that Gmail intrudes into your privacy, Gmail argues that only a very small number of people can access your emails and they would only have access to metadata. Therefore it is difficult to know the truth. Continue with a satirical video that contrasts a bit with the French advertising culture.
