 It's Monday, November 4th, 2013. I'm Addi Robertson, and although Katy Perry might have the most Twitter followers, she has nothing on the four-square ambassador of Arby's. This is 90 seconds on the verge. BlackBerry CEO Thorsten Heinz is out. The company has raised $1 billion from a group of investors, including Fairfax Financial, who was originally supposed to buy the company outright. This is no longer the case. Heinz will be replaced by interim CEO John Chen. Chen says that despite his growing losses, he has no intention of shutting down BlackBerry's handset division, and he believes the company can stage a turnaround. Chen isn't the only new leader in town. Tom Wheeler was sworn in this morning as the new chair of the FCC. He replaced his interim chair Mignon Clyburn, who had a small but ridiculously productive six-month stint. Clyburn signed off on Sprint buying Clearwire and SoftBank buying Sprint. But don't worry about Clyburn. She'll stay on the FCC's board as a commissioner until 2017. And finally, you'd better see the new Thor movie if you want to understand exactly what's going on in Marvel's TV show. The November 19th episode of ABC's Agents of S.H.I.E.L.D. is set to take place in the aftermath of Thor The Dark World, which will hit U.S. theaters this Friday. The move is similar to Marvel's strategy of using one film to set up or promote another, but unlike the film, it doesn't appear that Chris Hemsworth or Natalie Portman will be making cameos on the small screen. Meanwhile, Al Roker will not be making a Today show crossover appearance in the upcoming Hunger Games movie. And that's it for today's top stories. Coming up tomorrow, I continue to try to get Monster Mash out of my head. It's November 4th already, brain!
