Editing NAPLPS (section)

== One-way systems ==

Telidon-based [[teletext]] was tested in a few North American trials in the early 1980s &mdash; [[Canadian Broadcasting Corporation|CBC]] IRIS, [[TVOntario]], [[Manitoba Telecom Services|MTS]]-sponsored [[Project IDA]], to name a few.

NAPLPS was also part of the [[NABTS]] teletext standard, for the encoding and display of teletext pages.

In the late 1980s and early 1990s, affiliates of the regional sports network group [[SportsChannel]] ran a service called [[Sports Plus Network]], which ran sports news and scores while SportsChannel was not otherwise on the air. The screens, which frequently featured team logos or likenesses of players in addition to text, were drawn entirely with NAPLPS graphics and resembled the loading of [[Prodigy (online service)|Prodigy]] pages over a modem, though slightly faster.
