Abstract: A method is provided for distributing online content to one or more delivery units. A change in content from one or more sources is detected and gathered in real time. The content is extracted from the one or more sources. The content is matched in real time to a user's interest. The delivery of the content is determined, and the content is transmitted to the one or more delivery units based on the delivery determination.

Abstract: Systems and methods for visualization of real-time advertisement inventory are provided. An exemplary method for real-time display on a graphical user interface of advertisements delivered over a network is given. An identifier is displayed corresponding to a web site displaying an advertisement. Quantitative data is displayed with respect to the advertisement displayed on the web site. A type of content associated with the advertisement on the web side is displayed. A second web site for routing the advertisement is displayed. A frequency in which the advertisement is displayed on the web site is displayed.

Abstract: A method is provided of determining the how information from any information system changes over time. WebPages A through WebPages Z with nodes A through Z, are located, where A through Z are integers. Timestamp values for each of a node from A through Z are retrieved. Timestamp values from A are subtracted to create a denominator time value. A distance between the nodes A through Z is determined by calculating a number of edges in the digraph to create a numerator value. The distance is divided by the denominator time value to provide a velocity value.
