Feed aggregator

A feed aggregator is a website that contains material from a number of websites organized into various “feeds,” typically arranged by source, topic, or story. Feed aggregators often draw their material from a particular type of source, such as news websites or blogs, although some feed aggregators will contain content from more than one type of source. Feed aggregators generally display the headline of a story, and sometimes the first few lines of the story’s lede, with a link to where the rest of the story appears on the original website. The name of the originating website is often listed as well.
