When does Shark Tank return?

The show is the American franchise of the international format Dragons' Den, which originated in Japan as Money Tigers in 2001. Shark Tank has been renewed for its eleventh, twelfth, thirteenth and fourteenth seasons. The series has been a ratings success in its time slot.
The show features a panel of investors called "sharks," who decide whether to invest as entrepreneurs make business presentations on their company or product. The sharks often find weaknesses and faults in an entrepreneur's valuation of their company, product, or business model. The show is said to portray "the drama of pitch meetings and the interaction between the entrepreneurs and tycoons"
