In computing, a aggregator, also termed a feed aggregator, feed reader, news reader, RSS reader or simply an aggregator, is client software or a web application that aggregates syndicated web content such as online newspapers, blogs, podcasts, and video blogs in one location for easy viewing.
In a nutshell, an aggregator acts as a trusty middle man between you and VOD services like iTunes, Amazon, Google Play, and more. They handle encoding and delivery, and when your film generates revenue, they report and send it back your way.
Some sites try to collect videos of high quality or interest for visitors to view; the collection may be made by editors or may be based on community votes. Another method is to base the collection on those videos most viewed, either at the aggregator site or at various popular video hosting sites. Some other sites exist to allow users to collect their own sets of videos, for personal use as well as for browsing and viewing by others; these sites can develop online communities around video sharing. Still other sites allow users to create a personalized video playlist, for personal use as well as for browsing and viewing by others.
Though YouTube is the best-known video sharing site, plenty more sites feature free clips of crazy lip syncing, Mentos fountains, and even the odd useful how-to video. People are uploading hundreds of thousands of clips every day–how do you sort through them all?
