The most interactive and "Web-like" of the applications, the online connection made it possible to offer Transactional services. Many businesses looked to use videotex for Intranet-like applications within the enterprise.

A "non-networked" use of the videotex platform was in the interactive presentation of databased material. This usually took the form of Public Information Kiosks or Point of Sale presentations. Unlimited by bandwidth, standalone sites often incorporated Videodisks or other Multimedia.

One way to deliver mildly interactive information to the public was to embed the pages in the unused Vertical Blanking Interval (VBI) of a Broadcast Television channel, which could then be extracted and displayed when needed. This technique is similar to how we do "closed captioning" on TV.

Another variation of Teletext was to fill an entire cable TV channel with digital pages that could be retrieved by a specialized "reader" device. Though it offered limited interactivity, cabletext allowed immediate access to thousands of pages of information via your settop cable box.

Advances in colorized LED's, memory and support technologies made it possible to place animated electronic displays in a range of public venues: bars, hotels, sports arenas, financial centers, etc.
