SEASON PREMIERE: We’ve already had Shark Week, thanks to Discovery Channel’s annual escapades — and now it’s time for Shark Tank Week, with Mark Cuban and other high-rolling business types competing to find, and finance, the best ideas brought to them. Including, in tonight’s opener, an enterprising way to identify a bedbug infestation before calling in the exterminators. Creepy, sure — but profitable? Quite possibly.
