Figure 3. Defining Features of the 1960s Broadcast Architecture

This figure presents a conceptual matrix identifying the defining features of the 1960s American broadcast architecture within The Jurisdictional Signal Formatting Doctrine. The figure is derived from Table 3, Defining Features of the 1960s Broadcast Architecture, and is intended to establish the doctrine’s broadcast-scarcity baseline for later comparison with the modern platform environment. The figure identifies eight architectural features: limited channels, educational and public-affairs programming, high network authority, shared viewing windows, strong editorial gatekeeping, slower update cycles, limited audience interactivity, and a comparatively unified civic signal floor. Each feature is organized according to its description, civic signal effect, integrity benefit, and integrity risk. The purpose of the figure is not to present the 1960s media environment as morally superior to modern media. Rather, it explains how broadcast scarcity preserved shared interpretive overlap while also concentrating institutional control over public visibility, editorial selection, timing, and framing. The figure therefore highlights both the stabilizing and limiting characteristics of the 1960s broadcast system. In the context of the doctrine, the 1960s baseline is important because it shows how a bounded television-news environment could make it easier for citizens to recognize the same national events, even when they disagreed sharply about their meaning. At the same time, that shared recognition came at a cost: a small number of broadcasters exercised significant influence over what the public saw, when the public saw it, and which voices were included or excluded. This figure is designed as a full-page 8.5 × 11 landscape visual artifact for legal, policy, media, civic education, academic, and public interpretability. It supports comparative analysis between broadcast scarcity and later abundance-based platform architecture within The Jurisdictional Signal Formatting Doctrine.
