Blockgraph

Leading identity resolution platform for TV advertising backed by major media and distribution companies

Blockgraph is an identity resolution and data clean room platform specifically built for the television advertising ecosystem. Founded as a joint venture by Comcast, Charter Communications, and ViacomCBS (now Paramount), the company leverages blockchain technology to enable secure, privacy-compliant data sharing and audience matching between content owners, distributors (MVPDs), and advertisers. The platform addresses the critical challenge of cross-platform audience measurement and targeting in an increasingly fragmented TV landscape while maintaining strict data privacy and security standards. Blockgraph's technology allows multiple parties to match and activate audiences without exposing raw customer data, using cryptographic hashing and distributed ledger technology to create a trusted environment for data collaboration. The platform has become particularly relevant as the TV industry transitions from traditional linear broadcasting to streaming and addressable advertising models, where precise audience targeting and measurement are essential. By providing a neutral infrastructure owned by major industry players, Blockgraph has positioned itself as a key enabler of advanced advertising capabilities in connected TV (CTV) and linear television. The company serves major television networks, cable and satellite distributors, streaming platforms, and advertisers seeking to improve campaign targeting, reduce waste, and measure cross-platform reach. Blockgraph's industry-backed governance model and focus on privacy-preserving technology have made it a significant player in the evolving TV advertising technology landscape, particularly as privacy regulations tighten and third-party cookies deprecate.
