But one day I just pulled up Zocdoc because I wanted to find a dentist closer to home. Before doing so I had asked some colleagues for dentist referrals. I used Zocdoc five years ago, when I had first moved to Silicon Valley. In May they announced a Telemedicine service, and it seems like early adoption has been good for them. Users can select an available time slot, book an appointment and simply show up. Search results include ratings for each doctor based on reviews, which are verified to have come from actual patients. Zocdoc allows users to search according to their symptoms or desired specialist type, location and insurance plan.

Zocdoc was created to help patients book doctor appointments online. After thinking about this some more, I am now starting to question this assumption. A big reason for that is the belief that Patient Demand Aggregation in Healthcare will be difficult to pull off. My viewpoint has been that the Telemedicine market is likely to have multiple winners. One of the things I brushed over was Competition.
