Archive Index — Five Formats
Classic television, mapped by format.
Terrestrial broadcasting built its audience on a handful of recurring shapes: the studio sitcom, the continuing serial, the adventure series, the procedural, and the variety bill. This guide sets out how each one works, where it came from, and what tells one from another.
Start with whichever format you already love, or read the five in order and see how much of a week's schedule they once covered between them.
How To Use This Guide — Format Traits
One schedule, five shapes
Every format below grew out of the same handful of broadcasting constraints: a fixed studio, a weekly slot, and an audience watching live or close to it. What separates them is structure, not just subject matter, and knowing the structure is the fastest way to work out whether a series will suit you before you commit to a full run.
| Format | Typical setting | Episode structure | Good starting point if you like |
|---|---|---|---|
| Sitcom | Studio set, occasional location filming | Self-contained episodes, rare two-parters | Character comedy with a fixed cast |
| Soap opera | A permanent street, square or village set | Ongoing serial with no planned ending | Long-form community storytelling |
| Sci-fi & fantasy | Studio sets mixed with location work | Serial adventures, recurring cast and premise | High-concept storytelling across instalments |
| Crime drama | Police station, courtroom, city streets | Case-of-the-week or a serialised investigation | Procedure, moral weight, a strong lead |
| Light entertainment | A theatre stage before a live audience | A bill of sketches, music and guest turns | Variety over narrative |
