Edison Research SVP Tom Webster will leave the company at the end of May to focus on the podcast industry. “My work with Edison is far from over, and we have established an agreement to partner on many things in the future,” Webster shares via his blog here. “I’m excited about what is next, and I’ll have more to say on that in the next edition of I Hear Things, which isn’t going away, by the way.” Webster joined in June 2004 after time with MicroMass Communications, Puremix and Broadcast Architecture. No word on plans for the position.
