Alphonso

Pioneer in ACR-based TV data and cross-screen attribution, rebranded into LG's first-party CTV advertising platform

Alphonso, now operating as LG Ads Solutions following its 2021 rebrand, was founded as a TV data company specializing in Automatic Content Recognition (ACR) technology. The company built its reputation by embedding ACR software into smart TVs and connected devices to passively identify what content viewers were watching — enabling advertisers to close the loop between TV exposure and digital or in-store actions. Its data capabilities spanned linear TV, streaming, and OTT environments, making it a powerful tool for cross-screen attribution and audience targeting. Alphonso was acquired by LG Electronics, and in 2021 the company was rebranded as LG Ads Solutions, consolidating LG's advertising technology ambitions under a unified brand. The rebrand gave the platform direct access to LG's massive global installed base of smart TVs, dramatically expanding the scale of ACR data available for advertisers. Under the LG Ads Solutions banner, the platform offers media buying, audience targeting, and measurement solutions to brands and agencies seeking to reach connected TV audiences. During its independent years, Alphonso was considered a significant innovator in the TV measurement and attribution space, competing with companies like Samba TV, iSpot.tv, and EDO. Its ACR-based approach to understanding real-world TV viewership — rather than relying on panel-based estimates — positioned it as a forward-looking alternative to legacy measurement methodologies. The transition to LG Ads Solutions marked a broader industry trend of TV manufacturers leveraging first-party ACR data as a strategic advertising asset.
