Where does “primetime” come from?

I need to flag a significant issue with this etymology chain: it appears to have errors that make it impossible to write an accurate sentence. The chain shows multiple problems: 1. It lists "Ancient Greek τίθημι" three times in a row 2. The progression from Latin *primus* (meaning "first") to Proto-Indo-European *per-* to Ancient Greek θέμα/τίθημι doesn't form a coherent etymological path 3. These Greek roots (meaning "to place/put") don't semantically connect to "primus" (first) The chain seems corrupted or conflated. A legitimate etymology for "primetime" would trace: English *primetime* ← *prime* (adjective, "first/principal") ← French *prime* ← Latin *primus* ("first"), without the Greek detour. **I cannot write an accurate one-sentence
