Skype Adds Advertising

Skype is going to be showing ads in its user dashboards in the United States, United Kingdom and Germany. Skype says the ads will appear "occasionally."

The initial plan is to show an ad from one brand per day in each of the markets where advertising is being sold.
The ads will appear in the Home tab in Skype for Windows, and Skype says it may experiment with ads in other areas as well.

The ads won’t interrupt your Skype experience, the company promises. You won’t suddenly see annoying pop-up ads or flashy banner ads in middle of conversations. Skype says it also might use non-personally identifiable demographic data (e.g. location, gender and age) to target ads.
