Below are the top rated online news sources available today.

CNN.com is an extremely popular news site.
It is frequently updated with the latest news from CNN's staff of thousands both from the US and around the globe. The day's feature stories are constantly refreshed and updated, some featuring live streaming video streaming and audio.

CBS News provide extensive news coverage through their Web site from their existing CBS Worldwide Inc. team of correspondents. The site works well to bring not only the latest headlines, but the detail as well from their large resource of online news information. They also provide an email service so you can have the latest news delivered to your desktop.
ABCNews is part of the go.com family of leading Web sites and provide the latest news headlines along with some audio and video coverage in a well thought out and highly usable format.They also provide news by email with their news alerts service.
Google news offers a slightly different layout and is not as inviting as some of the other online sources. The top stories are layed out one after the other but they do offer continuous updates from around the globe. Below is the top 15 news sites based on people accessing them. Personally I prefer to look at CBS news because of the familiarity of the faces I see. I think this is because of television and the fact that I like to watch CBS news.
