  You can have a revolutionary idea without it being a new kind of product. For example Facebook did many things very differently than its competitors. Firstly it didn't show when you looked at others profiles, all previous networks did that and it makes people think twice before interacting with it. Secondly it solved real names, people actually used their real names at Facebook which made it easy to find real friends and old friends on it. Thirdly it only had an upvote button and no downvote making posting content at worst ignored instead of having to be scared of downvotes. These three taken together greatly increased growth and user engagement. Without them Facebook would never have became a company capable of rivalling Google. Google similarly just made a much better search engine than the competition. The revolutionary idea wasn't "Lets make a search engine", but "With this algorithm we can make the best search engine in the world, and that is worth a lot!".
