The Secret of the Times Square Billboards: A Street That Mandates Advertising

In every city in the world outdoor advertising is regulated. Size is limited, brightness is limited, sometimes it is banned outright. Times Square is the exact opposite.

Here, not hanging a billboard on your building is a zoning violation.

The city that made advertising compulsory

In the 1970s Times Square was less a tourist destination than a high-crime area. When redevelopment discussions began, a problem appeared. The new office buildings wanted clean glass façades — and that would mean losing the light that made this street what it was.

So New York created special rules for the district. The gist:

• Buildings in the district must install illuminated signage above a defined area
• Signage must meet a minimum brightness standard
• Brightness is defined in a unit created just for this street (LUTS, Light Unit Times Square)

It is not common for a city to invent a unit in order to measure advertising brightness on one particular street. In effect the ordinance preserved the image of a blazing Times Square in law. The scene tourists photograph today did not arise naturally — it was designed.

Billboard technology: brightness before resolution

The screens in Times Square have different requirements from the TV you know.

Brightness comes first

The biggest enemy is direct sunlight. To be visible at midday, the screen has to be brighter than the sun on it. Where an indoor TV runs at a few hundred nits, outdoor billboards put out thousands up to around 10,000 nits. Which is why brightness drops sharply and automatically at night. Run daytime brightness after dark and it is too dazzling to look at.

Pixel pitch is actually wide

These are screens viewed from a distance, so there is no reason to pack pixels tightly. The further the viewer, the wider the pixel pitch (the gap between LED elements). That is why up close a big board shows visible dots but reads smoothly from across the street. By the raw resolution number, many are lower than an ordinary TV.

Modular construction

A billboard is not one continuous screen but thousands of small LED panels (modules) joined together. When part of it fails, only that module is swapped. If you have seen a photo with one rectangle in a slightly different colour, that is a freshly replaced module.

Power and heat

A screen of several hundred square metres draws serious power and generates serious heat. Cooling and power distribution equipment sits behind it, and that maintenance cost is reflected in the advertising price. The move to LED cut consumption dramatically compared with the neon and incandescent era — one of the conditions that let this street keep growing.

How the price is set

This is what people most want to know, and the honest answer is “completely different for every screen.”

The factors that split the price:

Exclusive long-term contracts on large screens have been reported in the range of tens to hundreds of thousands of dollars a week. On the other hand, where several advertisers share time, the price comes into reach for individuals. That structure is why fans can put an idol’s birthday message on a Times Square screen. You are buying tens of seconds of exposure, and products in the few-hundred-dollar range exist.

What changed recently: the screens respond in real time

It used to be that ad footage was delivered in advance and played to a fixed schedule. Now a good many screens run programmatically. As with online advertising, real-time bidding decides which ad runs when, and the content changes according to data like weather, time of day and foot traffic on site.

Cameras and sensors are also used to count people in the plaza and compute exposure. It has shifted to a structure that estimates and bills for “how many people saw it.”

One misconception: advertising effectiveness

A Times Square ad is consumed as a symbol of success, but in pure advertising-efficiency terms it is not a strong medium. Foot traffic is heavy, but most of it is tourists with no relation to the purchase target.

So the real purpose of this street today is different. The goal is less the advertisement itself than the photos and videos of it spreading through social media. That is also why brand announcements, single releases and celebration events cluster here. The screen is a stage; the real reach happens online.

In short

1. The light of Times Square is mandated by zoning. Not hanging a billboard is a violation
2. A dedicated brightness unit (LUTS) was created to define a minimum brightness
3. Billboards prioritise brightness over resolution, and pixel pitch is actually wide
4. Price is set by position, size, exposure model and timing. Seconds-long products are within reach of individuals
5. The purpose of this street is now online spread more than on-site exposure

Frequently asked questions

Can an individual put an ad in Times Square?

Yes. On screens where advertisers share time there are products measured in tens of seconds, purchased through an agency. The screen and slot you want require advance booking and content review, and periods of concentrated demand like year-end are far more expensive.

How much electricity does it use running all night?

Since the move to LED it is far less than in the neon and bulb era, and brightness drops automatically at night. Even so, one large screen draws considerable power, requiring separate cooling and distribution equipment whose cost is reflected in advertising rates.

Why do you sometimes see a black rectangle on a screen?

Billboards are built from thousands of small LED modules joined together, so when some modules fail only that part goes dark. After replacement, that area can look subtly different in colour too.

How does the New Year’s Eve countdown ball work?

It descends by pulley along a pole atop One Times Square, with a surface made of crystal panels and LED lighting. The drop itself is mechanical; the lighting show is controlled by software.
