Personalcasting

Personalcasting, or personalized digital television (PDTV), is an application that uses news-on-demand algorithms to deliver tailored broadcast news (from radio or television) on a wide range of computing platforms including mobile phones and PDAs. Unlike podcasting, which is a series of digital media files (either audio or video) that are typically downloaded through web syndication, personalcasting automatically indexes, clusters and extracts information from news sources.
