Blockgraph's chief revenue officer Aleck Schleider said the platform brings political geographies and first-party data directly into TV planning and activation, creating a more responsive approach for the midterm cycle.

New Blockgraph launch enables faster custom audience targeting for political campaigns across TV in advance of the 2026 midterm cycle. Near real time capabilities give agencies more precise planning, activation, and measurement using political geographies and first-party data NEW YORK, NY, March 18, 2026 - Blockgraph, the platform that empowers advertisers to deliver results in the real-world, today announced the launch of its new custom targeting capabilities purpose-built to execute faster political campaigns and election-related initiatives. The new capabilities include the ability to target custom electoral audiences and legislative districts in addition to delivering seamless activation across linear and digital TV platforms including FreeWheel and Ampersand. Using Blockgraph's new political offering, available through the company's Blockgraph OnDemand platform, agencies, political data providers, and media sellers can create audiences using aggregated and de-identified first-party voter data, geographic definitions (state, DMA, city, ZIP, or ZIP+4), and electoral districts.
