Variety: Al Roker is reaching from the solid ground of NBC’s “Today” to the shakier terrain of TV’s future. While many TV viewers know Roker from his years spent forecasting weather for “Today,” fewer know that he has a small TV-production company. The shop, Al Roker Entertainment, will this week launch three new “shows” that he will transmit via Meerkat, the mobile app that allows users to watch live streaming video. Each of the programs will last five to fifteen minutes, and Roker freely admits he’s experimenting. “It’s sort of like radio in the 1920’s. Why not take a shot at it?”
