AdExchanger Podcast: Infillion-Foursquare, Taboola-Dianomi, WarnerMount Merger

Executive Signal Summary

This AdExchanger podcast episode discusses two ad tech acquisitions from last Friday: Infillion's acquisition of Foursquare, adding location data to its ad tech stack, and Taboola's acquisition of Dianomi, targeting the finance vertical. Editor-in-Chief Allison Schiff provides rationale and potential synergies. The episode also covers the Warner Bros.-Paramount merger, now dubbed 'WarnerMount', as the major antitrust hurdle was resolved when California and 11 other states settled their lawsuit. Paramount had threatened to leave California, which pressured the settlement. A new legal challenge emerged but is seen as less formidable. The discussion highlights the strategic moves in ad tech consolidation and the significant regulatory scrutiny on major media mergers.
