Season 4, Episode 21: Taylor and Jason develop an innovation for coolers, an industry with only 3 major competitors! Their idea is to put LED lights in a cooler to make it easier to find what you’re looking for in the dark. The sharks point out that they’ll never be successful selling their own coolers in such a concentrated market and will have to license their technology to one or more of the big players. This is an excellent discussion starter for oligopolistic competition and barriers to market entry.
