Zenith didn't just keep up with electronics; it kept inventing the categories. Today, as LG Electronics' U.S. research subsidiary, that same engineering drives the technology behind the screens in your home, your hotel, and the broadcast signal itself.
Behind every Zenith milestone is a piece of engineering the rest of the industry spent decades catching up with.
The Space Command needed no batteries. Pressing a button drove a tiny hammer into one of four aluminum rods, ringing out a precise ultrasonic tone — too high for human ears, but unmistakable to the receiver inside the set. It ruled living rooms for a quarter century.
Polley and Adler shared a technical Emmy in 1997 for the invention that reshaped the evening.
How do you send left and right audio over a single FM broadcast — and keep it working for the millions of mono radios already out there? Zenith's pilot-tone multiplex scheme became the FCC standard in 1961, and it's still the system radios worldwide transmit on today.
It joined a run of firsts: the first portable radio (1924), push-button tuning (1927), subscription TV "PhoneVision" (1947), and the Chromacolor picture tube (1969).
Zenith merged with LG Electronics in 1999. Today the Zenith R&D Lab in Lincolnshire, Illinois is LG's U.S. research subsidiary — leading work in broadcast standards, hospitality, and healthcare technology. The lightning bolt now travels with one of the world's largest electronics innovators.
Zenith-born technologies run the in-room experience at properties across the country — and get it live fast.
Invented by Zenith in 2004, Pro:Idiom is a robust, highly secure digital-rights-management system built specifically for the hospitality and healthcare markets — lower cost, less maintenance, world-class encryption. As the creator and exclusive licensor, Zenith protects an installed base of more than three million devices, the reason hotels and hospitals can deliver premium HD content with confidence.
Pro:Idiom details →Pro:Centric is LG's hospitality TV platform, built on webOS and protected by Pro:Idiom. Through Pro:Centric Direct and the cloud-based Pro:Centric Stay, properties brand their TVs, push interactive services — room service, weather, local info, OTT streaming and casting — and manage entire fleets from one console. SI partners can provision rooms, monitor status, and update firmware without ever walking the hallway.
Zenith's WMI replaces remote-and-menu setup with a browser. Installers provision, brand, and configure commercial displays wirelessly from a phone or tablet — applying channel maps and pushing settings to whole room groups — cutting install and configuration time from hours to minutes.
How it works →Zenith's vestigial side-band transmission was adopted in 1996 as the centerpiece of the ATSC digital-TV standard — the way America's airwaves still carry broadcast television.
Technical Emmys for the wireless remote, HDTV, MTS stereo TV sound, and flat-screen CRT technology — Zenith and its people hold more Consumer Electronics Hall of Fame inductions than any other company.
Core innovations behind the broadcast standard for mobile digital TV (ATSC, 2009) and the Mobile Emergency Alert System (2013) — delivering rich-media alerts when they matter most.
With LG's global scale behind it, the Zenith lab is building the next generation of television, hospitality, and connected experiences.
Core LG and Zenith technologies sit in every layer of ATSC 3.0 — the majority of the FCC-adopted physical-layer standard. Branded NextGen TV, it fuses broadcast and broadband for 4K HDR, immersive audio, interactivity, and datacasting. The future of television, and Zenith helped write the rules.
Building on M-EAS, the Advanced Warning and Response Network leverages ATSC 3.0 to push reliable, rich-media emergency alerts to fixed and mobile receivers — anywhere, anytime — even when cellular networks are overwhelmed.
Debuted in 2025, Pro:Centric+ turns the in-room TV into a business platform: AI-driven energy management aware of room status, dynamic ad insertion, location services for asset tracking, Wi-Fi health monitoring, and smartphone-based provisioning — plus AI integrations for smart thermostats, leak detection, and staff-safety alerts.
The same hospitality DNA extends to healthcare — secure, interactive patient-room systems that bring entertainment, education, and care-team communication to the bedside.
Non-real-time datacasting, personalized content, and targeted delivery blur the line between the airwave and the internet — a connected broadcast layer that scales to every screen.
In cooperation with LG's Convergence Lab in Seoul, the Lincolnshire team turns global research into U.S.-ready products — carrying a century-old promise of quality into the technologies of tomorrow.
AI aimed at a business outcome, not a science experiment — content that adapts, fleets that self-report, and operations that get simpler. We measure it in hours saved and problems solved, not novelty.
Hardware and software, stood up in days. We build rigs and working builds, test them in real conditions, and iterate fast — the art of the possible, made tangible.
