Millennial Media

Millennial Media was a mobile advertising / adtech company surfaced as a portfolio company of bessemer-venture-partners and added to the API Evangelist network as a stub for enrichment. The enrichment probe (2026-07-20) found the company is defunct: millennialmedia.com now CNAMEs to rc.yahoo.com via AWS Global Accelerator on oath.cloud (Yahoo / Verizon Media / Oath infrastructure, consistent with the AOL acquisition of Millennial Media), and every host returns HTTP 404. There is no independent millennial-media developer portal, API, developer.* or api.* subdomain (NXDOMAIN), and no /.well-known/ or /llms.txt discovery surface. No API artifacts exist to enrich; this record is retained as a historical/company lead only.

Millennial Media is profiled on the APIs.io network. Tagged areas include Company, Advertising, AdTech, Mobile Advertising, and Defunct.
