ISPs, News Servers, and Newsfeeds
Many Internet service providers, and many other Internet sites, operate news servers for their users to access. ISPs that do not operate their own servers directly will often offer their users an account from another provider that specifically operates newsfeeds. In early news implementations, the server and newsreader were a single program suite, running on the same system. Today, one uses separate newsreader client software, a program that resembles an email client but accesses Usenet servers instead. Some clients such as Mozilla Thunderbird and Outlook Express provide both abilities.
Not all ISPs run news servers. A news server is one of the most difficult Internet services to administer well because of the large amount of data involved, small customer base (compared to mainstream Internet services such as email and web access), and a disproportionately high volume of customer support incidents (frequently complaining of missing news articles that are not the ISP's fault). Some ISPs outsource news operation to specialist sites, which will usually appear to a user as though the ISP ran the server itself. Many sites carry a restricted newsfeed, with a limited number of newsgroups. Commonly omitted from such a newsfeed are foreign-language newsgroups and the alt.binaries hierarchy which largely carries software, music, videos and images, and accounts for over 99 percent of article data.
There are also Usenet providers that specialize in offering service to users whose ISPs do not carry news, or that carry a restricted feed.

Famous quotes containing the word news:
“Word of gloom from the war, one day;
Johnston pressed at the front, they say.
Little Giffen was up and away;
A tear—his first—as he bade good-by,
Dimmed the glint of his steel-blue eye.
“I’ll write, if spared!” There was news of the fight;
But none of Giffen.—He did not write.”
—Francis Orrery Ticknor (1822–1874)
