push media
push media
(messaging)A model of media distribution where items of
content are sent to the user (viewer, listener, etc.) in a
sequence, and at a rate, determined by a server to which the
user has connected. This contrasts with pull media where
the user requests each item individually. Push media usually
entail some notion of a "channel" which the user selects and
which delivers a particular kind of content.
Broadcast television is (for the most part) the prototypical example of push media: you turn on the TV set, select a channel and shows and commercials stream out until you turn the set off.
By contrast, the World-Wide Web is (mostly) the prototypical example of pull media: each "page", each bit of content, comes to the user only if he requests it; put down the keyboard and the mouse, and everything stops.
At the time of writing (April 1997), much effort is being put into blurring the line between push media and pull media. Most of this is aimed at bringing more push media to the Internet, mainly as a way to disseminate advertising, since telling people about products they didn't know they wanted is very difficult in a strict pull media model.
These emergent forms of push media are generally variations on targeted advertising mixed in with bits of useful content. "At home on your computer, the same system will run soothing screensavers underneath regular news flashes, all while keeping track, in one corner, of press releases from companies whose stocks you own. With frequent commercial messages, of course." (Wired, March 1997, page 12).
Pointcast is probably the best known push system on the Internet at the time of writing.
As part of the eternal desire to apply a fun new words to boring old things, "push" is occasionally used to mean nothing more than email spam.

push technology
Transmitting data from an internal network or a cloud-based service to the user's computer or mobile device. Notifications for a wide variety of events such as stock quotes and Facebook posts are pushed in real time. In contrast, email is typically pushed when users open their mail program. Application updates may be automatically pushed when the app is opened or only when requested by the user.Push Is Automatic - Pull Requires a Request
Contrast push with "pull" technology, in which the user initiates a request for the data each time. Retrieving a Web page is an example of the pull model.
PointCast Was the First
In the mid-1990s, PointCast was the first Internet product to become popular for pushing selected news and stock quotes into a user's computer (see PointCast). See real time, BackWeb and Active Channel.
