Home information services once offered an interactive, graphics-rich selection experience. What was this user-selectable on-demand system called?

Introduction / Context:Before the modern web, interactive information services for homes and kiosks emerged that allowed users to browse pages of text and graphics over phone lines or cable. These systems laid groundwork for later online experiences.

Given Data / Assumptions:

• Interactive, user-selectable content at home.
• Graphics-rich presentation compared to plain text services.
• Menu-driven navigation over telecommunications links.

Concept / Approach:The term for that family of services is Videotex (including variants like Viewdata and Minitel). Videotex offered two-way interactivity, menu navigation, and graphical pages transmitted digitally to a terminal or TV adapter.

Step-by-Step Solution:

Verification / Alternative check:Historic examples like France's Minitel are classic Videotex platforms: searchable directories, messaging, and information retrieval with menu graphics.

Why Other Options Are Wrong:

• Teletex system: Enhanced Telex for office messaging, primarily text-oriented, not the consumer interactive graphics system described.
• Fax system: Transmits images of documents point-to-point, not menu-based interactive services.
• Microwave system: A radio transmission method, not an end-user information service.
• None of the above: Incorrect because Videotex precisely fits.

Common Pitfalls:Confusing Videotex with Teletext (broadcast one-way) or Teletex (office messaging). Only Videotex provided interactive, user-selectable pages over two-way links for home users.

Final Answer:Videotex system
