The past few years have seen an increase in the availability of video content on the World Wide Web and the demand for such content will keep increasing dramatically. Consumers want more content to be made available, in higher quality, and to take full advantage in their living rooms of high definition television. The video industry (television and cable networks, content producers, content delivery systems, etc.) is looking at ways to be ahead of the demand and be on top of the next wave of innovations in the domain. Several factors could slow down the increase, such as lack of interoperability, unsearchable or inaccessible content, or digital rights.

The World Wide Web Consortium completed an important link between Semantic Web and microformats communities. With 'Gleaning Resource Descriptions from Dialects of Languages', or GRDDL (pronounced "griddle"), software can automatically extract information from structured Web pages to make it part of the Semantic Web. Those accustomed to expressing structured data with microformats in XHTML can thus increase the value of their existing data by porting it to the Semantic Web, at very low cost.
