Match of the Day: Season 1969/70

Season overview

Topic: "Match of the Day" Season 6.
Constraints: Use only provided SYNOPSIS and SOURCES.
Output Format: Valid JSON only.
JSON Keys:
overview: 160-220 word factual summary of the season's narrative arc.
primer: Array of exactly 4 concise bullet points summarizing essential previous lore, character positions, and stakes.
Style: Meticulous archivist, neutral, encyclopedic, plain text (no markdown/asterisks/headings/bullets in the text itself), no invented details.
SYNOPSIS: "From 1969, the programme becomes live and studio based, rather than being pre-recorded at the ground of the featured match, and there were now two games seen each week."
SOURCES:
TMDB Title: Match of the Day (1964).
Genre: Talk and News.
Description: BBC's football highlights and analysis.
Fact: "The longest-running football television programme in the world" (Guinness World Records).
Overview Requirement: 160-220 words.
Problem: The provided synopsis is extremely short (one sentence). It describes a change in format starting in 1969.
Constraint Check: "You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES. You never invent or guess... If a detail is not in the provided material, you omit it rather than guess."
Conflict: I cannot reach 160-220 words without inventing details or repeating the same sentence multiple times, which violates the "encyclopedic prose" and "do not invent" rules. However, the prompt demands a 160-220 word summary.
Strategy: I must look for any other information. There is none. If I write a 160-word summary based on one sentence, it will be repetitive or I will have to hallucinate.
Wait: Let's re-read the synopsis. "From 1969, the programme becomes live and studio based, rather than being pre-recorded at the ground of the featured match, and there were now two games seen each week."
Can I expand on the context? The source says it is "BBC's football highlights and analysis" and "The longest-running football television programme in the world".
Drafting Overview: Starting in 1969, Match of the Day underwent a significant format change
