Republic (Republic TV and Republic World) is India’s first independent media tech company. Founded by Arnab Goswami and launched in 2017, Republic TV is India’s most watched english news channel from its week of launch.

Gramener partnered Republic TV for the first time for an exclusive coverage of the Gujarat Assembly Elections 2017. The objective of the partnership was to do real time election data analysis on counting days with cutting edge analytics and visualization tools. The objective was to deliver the TV audience important valuable as election stories.

The partnership to deliver crystal clear election insights with real-time dynamic visualization continued during Assembly Elections 2018, and the General Elections 2019.


Election battles are a massive affair of interest for the general public as well as the media houses. News channels covering the elections with comprehensive data and narratives bags huge prime time viewership. In such a scenario, Republic TV needed a competitive edge while delivering election stories.

The Indian General Election is the biggest in the world. It involves over 300 political parties, 8,000 candidates, 800 million voters, and 1 million voting booths served and secured by 20 million officials. There is a variety of structured and unstructured information such as candidate histories, crime records, and declared assets to tap data from. In addition to this is the frenetic activity on the day of results. Live streaming of results happens while over 21,000 votes are counted each second, in all corners of the country, which spans an area of nearly 1 million square miles.

Thus, elections are a classic BIG DATA problem.

On the day the votes were counted, Republic TV had real-time data flowing in. This election reporting needed new analytics and visualization techniques to automate election insights discovery so that journalists can do what they are good at doing, but faster and better.


Effective visual data journalism goes beyond just the conventional charts and tailors the data into an effective story. Gramener engineered insightful election data visualizations to help Republic TV reporters offer interesting facts from the General Election 2019.

The whole project from ideation to execution was done over three-week period. A 10-member team consisting of designers, developers and testers worked in an agile fashion, building visual storyboards, iterating them based on input and making them ready for primetime.

Visual data journalism has added substance to election reporting. The nature of election reporting has become number centric, with 60 years of data to draw upon. With Gramener’s expertise, the indian public, especially the electorate was exposed to data-based reporting with hard facts and numbers, which are easy to consume as data stories.

The same analytics and visualization techniques helped in reporting the five weeks of polling, by providing live facts on phase-wise voter turnouts, exit poll surveys etc.

Live data feeds need to be analyzed, visualized and data stories need to be reported real time on national television. Accuracy, speed and ease of consumption was put to test in front of the entire nation.

Gramener’s data science platform – Gramex, was programmed to develop an election results dashboard which were to meet these expectations. Particular care was taken to enable real-time slice/dice of data for deeper insights as they streamed in. It had to be a novel approach, far removed from plain reporting of live numbers which had been the norm until then.


It was not only a new era in election reporting, but it was an epitome of collaboration between mass media and technology companies. Charged with this confidence, Gramener is now getting into gear as another large democracy prepares to choose future leaders – The 2020 US elections!
