Today we’re announcing that Bryan Lee is retiring from Microsoft, to pursue personal interests. J Allard, already instrumental in shaping Microsoft’s music strategy, will be taking over Zune responsibilities. From the start of the project, J has shared overall responsibility for Zune. Bryan was looking after marketing and business development for example and J had responsibility for the design and technology of Zune. As anyone who works in a big company knows, change is the only constant. Organizations evolve and change over time, and Zune is no different.
