Vadio is building a business off the YouTube API. The company also has its own technology for translating a list of songs into music video playlists no matter where the videos are stored. Vadio has already seen interest from radio stations, because the product is more appealing than simple audio and increases listener engagement.
The Web is based on a rather simple notion: There are Web servers and there are clients, such as browsers. It’s an asymmetric kind of a connection: Clients connect to servers to request stuff. This breaks when what we need is more interactivity--for example, when our online webmail service notifies us of a new email, an update to a stock tick or news item, or the ring of our virtual phone. To achieve that, we hack our way with things like XHR, SSE and, recently, WebSockets.
