Nemani Harsha Vardhan supervised by Prof. Ponnurangam Kumaraguru received his  Master of Science –  Dual Degree in Computer Science and Engineering  (CSD). Here’s a summary of his research work on Patterns and Influence of Advertising in Print Newspapers:

The fundamental question of whether advertising revenue compromises editorial independence has long been debated in media studies, yet empirical evidence has remained limited due to the difficulty of systematically analyzing large-scale newspaper content. This thesis investigates the relationship between advertising practices and editorial coverage in Indian print media, examining whether companies that advertise more receive more favorable or extensive news coverage. To conduct this investigation, we developed a scalable computational pipeline employing advanced image processing and Optical Character Recognition (OCR) techniques to systematically extract articles and advertisements from digital versions of print newspapers with high accuracy. This methodology enabled us to process and analyze content on a larger scale, overcoming traditional limitations in media content analysis. Our automated approach successfully parsed newspaper layouts, distinguished between editorial and advertising content, and extracted text with sufficient precision for quantitative analysis. Applying this pipeline to five prominent newspapers that span multiple regions and three languages—English, Hindi, and Telugu—we assembled a comprehensive dataset comprising more than 12,000 editions and several hundred thousand advertisements collected over six years. These newspapers collectively reach a readership exceeding 100 million people, making our analysis representative of India’s diverse print media landscape. The data set includes publications with varying editorial orientations, geographic focus, and readership demographics, providing robust coverage of the Indian print media ecosystem. Our analysis reveals several significant findings on contemporary print advertising practices and their potential influence on editorial content. Despite declining print circulation trends, advertising levels have remained remarkably consistent over the six-year study period, suggesting advertisers continue to value print media’s reach and credibility. We observe systematic patterns in ad placement, with corporate advertisements appearing disproportionately on prominent pages, while government advertisements contribute a substantial portion of overall advertising revenue. The data also reveal temporal patterns in advertising intensity, seasonal variations between different advertiser categories, and regional differences in advertising strategies. 

Most importantly, our regression analyses provide strong empirical evidence that advertising expenditure is correlated with editorial coverage patterns. Companies that advertise more heavily in a newspaper receive significantly more extensive coverage, and this coverage tends to be more favorable in sentiment compared to non-advertising entities. This relationship remains statistically robust for different model specifications, time periods, and advertiser popularity levels. The effect is particularly pronounced for  corporate advertisers, suggesting that commercial relationships may indeed influence editorial decisions in ways that could compromise journalistic independence and potentially mislead readers about the true newsworthiness or merit of covered entities.
