What Is a Lower Third?
A lower third is the graphic overlay sitting in the bottom portion of the frame that tells you who is talking, usually a name and a title, sometimes a location or a date. It is one of the oldest pieces of broadcast language still in daily use, and it is also one of the easiest things to get wrong: hold it too long and it clutters the frame, cut it too short and nobody reads it, skip it entirely and the viewer spends the next thirty seconds wondering who they are watching.
Origin Story
How a Greek centaur ended up naming a TV graphic
The first electronic graphics generator for television was built by Systems Resource Corp. in the mid-1960s, adapting display technology originally developed for airport arrivals and departures boards. CBS Laboratories picked it up and used it to identify speakers during the chaotic 1968 political conventions, exactly the use case a lower third still serves today. The company's engineers later named a follow-up system the Chiron, after the wise centaur of Greek mythology, and the product sold so well that the company itself changed its name to match. "Chyron" stuck as an industry term for on-screen text long after the original company became one vendor among many, the same way "Kleenex" outgrew the brand that coined it.
The Job
What a lower third is actually for
Its only job is identification and light context: who is this, and why should the viewer care what they are about to say. That is it. A lower third is not a place for a tagline, a joke, or a paragraph of biography. The moment it tries to do more than identify, it starts competing with the person talking for the viewer's attention, and it loses that fight every time because a viewer's eyes go to a moving mouth before they go to static text.
Anatomy
The parts of a lower third that actually work
A well-built lower third leads with a bold primary line, almost always the name, set larger and heavier than everything else in the graphic. A quieter secondary line carries the title or context: job title, location, or a one-line description of why this person is relevant. A backing element, a solid bar, a soft gradient, or a simple shape, separates the text from the footage behind it so it stays legible regardless of what is happening in the shot. Skip the backing element on a busy or bright background and the text becomes unreadable exactly when a viewer most needs to read it.
Case Study
How cable news chyrons became their own genre
Cable news pushed the lower third furthest from its original identification-only role. During the 2017 Senate Intelligence Committee hearing with former FBI director James Comey, CNN, MSNBC, and Fox News all aired the testimony live, and The Washington Post's graphics team tracked what each network chose to display in that same lower-third space in real time, turning the chyron itself into a measurable editorial choice, not just a name tag. By the late 2010s, cable news chyrons had become distinctive enough as their own format that the Post ran a dedicated feature on how the different networks' banners had evolved a house style, sharp, reactive, occasionally sarcastic, that had almost nothing to do with the original 1968 use case of simply telling viewers who was speaking.
Timing
How long to hold a lower third on screen
Hold it long enough to be read twice, roughly four seconds for a standard name-and-title graphic, then let it fade. Re-show it only if the person has been off screen long enough that a viewer might reasonably lose track of who they are, not every time they speak again in the same continuous scene. Re-identifying someone every ten seconds trains the audience to ignore the graphic entirely, which defeats the point of having it.
When To Skip One
When a lower third gets in the way instead of helping
Skip a lower third when the person has already been clearly identified elsewhere in the piece, in narration, in a previous on-screen introduction, or when the frame is already carrying another graphic and adding a second one would clutter a shot that needs to breathe. The goal is always clarity for the viewer, and sometimes the clearest choice is restraint.
Planning Ahead
Building lower thirds into the pre-edit, not as an afterthought
Deciding who needs a lower third, and what their title should say, is a story decision, not a graphics decision, which means it belongs in the paper edit stage, not bolted on after picture is locked. While arranging selects in ScriptCut, note each speaker's name and role as you build the sequence, then hand that off with the exported timeline and script, each cue already tied to an exact timecode, so whoever builds graphics in the finishing pass already knows exactly who needs identifying and when, instead of reconstructing that list from scratch while watching the cut back.

frequently asked questions
A lower third identifies who is on screen, usually a name and title, and sometimes adds context like a location or date.
Chyron comes from the Chiron Corporation, whose character-generator graphics systems, named after the centaur of Greek mythology, dominated broadcast news starting in the late 1960s and 1970s.
Roughly four seconds, long enough to be read twice, then fade it out rather than leaving it on screen throughout the person's appearance.
Only if they have been off screen long enough that a viewer might reasonably lose track of who they are, not every time they start speaking again in the same scene.
A bold primary line for the name, a quieter secondary line for the title or context, and a backing element that keeps the text legible against any footage behind it.
Not exactly. Cable news chyrons evolved into a much more editorial, reactive format, tracked and analyzed by outlets like The Washington Post, while a documentary lower third generally sticks closer to simple identification.
