News Stream



Show time-sensitive items in a reverse chronological list, with the latest items at the top. Update it dynamically, and combine the items from different sources or people into one single stream.

Use when

Your site or app uses one or more communication channels, such as blogs, email, social site updates, or news sites, to deliver timely content to users.

This channel may be personal—a user “owns” it, like an email client or Facebook friends list—or public, such as a website or public Twitter stream.


People can keep up with a news stream easily, since the latest items reliably appear on top with no effort on the part of the user. They can check in often and be assured of seeing what they need to see.

This pattern supports the Microbreaks behavior pattern in Chapter 1. A glance at a News Stream application can give a user lots of useful information (or entertainment) with very little time or effort.

From the perspective of a publisher, such as a website, having a News Box (Chapter 9) or the equivalent on your main page lets visitors see what’s new and noteworthy at your organization. Large organizations in particular may have many initiatives going on that would interest visitors: new products, blog entries, videos, news articles, charity work, and other content.


List incoming items in reverse chronological order. If the technology permits, “push” new items onto the top of the list without waiting for the user to request an update, but offer a way for the user to get an immediate update or refresh anyway.

Very busy streams can be split up into manageable substreams by topic, sender, source, search terms, or other factors—you could let the user choose which one(s) to show. Services such as Facebook, FriendFeed, Twitter, and some RSS readers show clickable lists of these substreams to the left or right of the incoming content (thus implementing the Two-Panel Selector pattern). Others, such as Tweetdeck, use Many Workspaces to show multiple parallel panels of incoming content.

Information shown with each item might include:

  • What: For short micro-updates, show the whole thing. Otherwise, show a title, a teaser that’s a few words or sentences long, and a thumbnail picture if one is available.
  • Who: This might be the person who wrote an update, the blog where an article was posted, the author of said article, or the sender of an email. Actual person names humanize the interface, but balance this against recognition and authoritativeness—the names of news outlets, blogs, companies, and so forth are important, too. Use both if that makes sense.
  • When: Give a date or timestamp; consider using relative times, such as “Yesterday” and “Eleven minutes ago.”
  • Where: If an item’s source is a website, link to that website. If it comes from one of your organization’s blogs, link to that. (But here’s another interpretation of “where”: can you get geolocation data about the item, and show it on a map?)

When there’s more to an item than can be shown easily in the list display, show a “More” link or button. You might design a way to show the entire contents of an item within the News Stream window. The News Stream is a list, so you can choose among Two-Panel Selector, One-Window Drilldown, and List Inlay. Examples abound of each model.

Give the user ways to respond immediately to incoming items. Stars, thumbs-up, liking, and favoriting are available in some systems—these all provide low-effort feedback and “handshaking” among people who don’t have time to write out long replies. But allow those long replies to be written, too! By placing controls and text fields immediately next to an item in a News Stream, you encourage responsiveness and interaction. This is usually a good thing in social systems.

Sharing of items, either privately via email or semipublicly via a provided social service, is also common in these interfaces. See the Sharing Widget pattern in Chapter 9.

News Stream designs for mobile devices are fairly straightforward as of this writing. Almost all of them devote the full screen to a single list—often a Thumbnail-and-Text List (Chapter 10) with richly formatted text—and users can drill down to an item by simply tapping or clicking it in the list.

Many News Stream services, including Twitter and Facebook, use the Infinite List pattern (see Chapter 10) for both their mobile and full-screen designs. This pattern lets users load a page or two of the most recent updates, and gives the option of loading more to go “backward in time.”

Some resources use the term “activity stream” for a very closely related concept: the time-ordered stream of actions (usually social actions) performed by a single entity such as an individual, system, or organization. This is a useful concept, and it doesn’t really conflict with the News Stream pattern, which talks about the stream of activities that are of interest to an individual or group of users, not generated by them. News Streams will usually have multiple diverse sources.


Digg and Google News are both public News Streams. Their purposes and designs are very different, but they share some of the features talked about in this pattern. Digg shows all incoming items in one large list; Google News splits them into topics, within which the most recent news articles are shown first. (Drilling down into the topic shows a page with a single list.) Both show comparable item information: title, teaser, linked source, and a relative timestamp. They use human names: Digg shows the submitter’s name, while Google News shows the article author’s name. And on both sites, you can mark items of interest—with a “digg” in one, a star in the other—and share them via email.


Google News

The previous two examples show public News Streams; the next two show personal News Streams.

Social networking services, news aggregators, and private communications (such as email) provide plenty of examples of personal News Streams. Below we see Facebook and Google Reader, which is an RSS-based aggregator. They both use a single reverse chronological list of items, each of which shows a linked source, title and teaser (when appropriate), author name, and relative timestamp. Users can “like” items, share them, and follow links to read more.

But note the differences, too. Google Reader lets the user split a potentially huge combined stream into substreams, based on source and topic; these are displayed in a selectable tree list on the left, thus making the window a Two-Panel Selector. Facebook doesn’t give the user this option by default, as of this writing. Instead, it automatically (and unpredictably) switches between a filtered “Top Stories” view, and a “Most Recent” view that shows everything. However, Facebook excels at the immediate response. Posting a short comment to a Facebook entry is almost as easy as thinking about it.
