As the digital media world continues to evolve there are a number of parties that are having to reinvent themselves. Publishers are all moving towards launching their own ad exchanges, which means that the SSP vendors and DSPs are going to be busy! I have a feeling the map of the landscape is going to look a lot more complicated than a Paris subway map so I’ll leave others to draw the picture. I wonder whether Australian operations like Fairfax, and others, are having to rethiink their Exchange strategies? Either way the days of the Ad Network as you knew them, are over!
