Rotten Tomatoes began as a hobby project. Senh Duong, the original creator, started posted reviews for movies he enjoyed on a small, personal website. Pretty soon after he began, lots of people started relying on those reviews in order to choose the movies they wanted to watch, and the site's traffic began growing exponentially.

Unable to handle the growth by himself, Senh turned to two friends he used to enjoy watching movies with back in college -- Patrick Lee and Stephen Wang -- and, together, the three college buddies decided to turn the little move review website into a business.

That business became RottenTomatoes.com, which is still one of the most popular and trusted online resources for movie reviews. You can hear the story of how all three original founders built it on this special, 75th episode of Web Masters.
