Hundreds of millions of people use Skype for its free voice over IP (VoIP) services every day. Indeed, Skype claims that in March 2012, 35-million people were all talking at the same time on the service. But, how many of them are going to stick with it when Microsoft, Skype’s owner, sticks ads in your face?

Microsoft announced that “While on a 1:1 audio call, users will see content that could spark additional topics of conversation that are relevant to Skype users and highlight unique and local brand experiences. So, you should think of Conversation Ads as a way for Skype to generate fun interactivity between your circle of friends and family and the brands you care about.” Oh yeah, I always like having an ad pop-up when I’m talking to a friend or co-worker.
