I never understood why they would let a reality tv show cover TechStars. The problem I see is that you have misaligned incentives. From what I know of Techstars, their goal is to help these entrepreneurs through what is probably one of the most exciting/stressful time of their lives as they build their pretty awesome businesses.
From what I know of reality tv shows, it's to entertain people with extreme stories that are easy to digest and with little to no depth.
