Adweek, which broke the story on Thursday that Mark Rosenthal was out at Current TV wrote in a follow-up story, "Sources close to Current TV say that the departure of Current TV CEO Mark Rosenthal comes two months after the network’s co-founder, Joel Hyatt, took the position of co-CEO alongside Rosenthal in a move that was never publicly announced."
The article later notes, " ‘[Rosenthal] came on-board to be CEO and not Co-CEO,” says one of those sources. ‘It was difficult for the team, and he saw that… After a certain amount of time, he decided it wasn’t working for him or anybody.’ What wasn’t working? ‘Decision-making. Communication,’ adds this source, ‘If there’s more than one person overseeing the day-to-day functions, it becomes confusing who the ultimate decision-maker is. I think for all of the staff, when you have two people, [you start to ask] who’s really in charge?’ "
Rosenthal served previously as CEO of Initiative Media, and before that as presidnet and COO of MTV Networks. He was serving on Current’s board of directors when he took over the CEO position from Hyatt in February, 2009.
According to Deadline.com, "Reached late Thursday, Rosenthal said ‘Joel [Hyatt] and I always had a great collaboration and we remain close friends. And Joel was instrumental in negotiating for Keith Olbermann to come to Current.’ "
