PLATFORMS OVER POSTERS: A COMPARATIVE ANALYSIS OF DIGITAL ADVERTISING EFFICIENCY IN THE 2026 TAMIL NADU ELECTION

The most significant finding concerns the role of organic (unpaid) amplification in the TVK campaign. Exit polling data suggests that approximately 62% of TVK voters first encountered the party through WhatsApp forwards or social media shares from friends and family, rather than through paid advertising. Among first-time voters, this figure rose to 78%. This peer-driven discovery mechanism dramatically reduced the TVK’s required paid advertising spend. Rather than paying to reach each voter directly, the campaign paid to seed content that spread organically through existing social networks. The fan club network of 85,000 clubs functioned as an initial seeding mechanism, with each club member circulating content to their personal networks. The DMK, by contrast, relied almost entirely on paid reach. While the party’s ads reached large audiences, each impression came at a cost. There was no equivalent organic amplification mechanism, as the party lacked a distributed network of trusted messengers.
