The government-backed Broadband Delivery UK scheme, which aims to increase the national reach of superfast broadband across the country, spent just over £5 million of its budget on publicity between September 2014 and February 2015.
That is the main finding to emerge from new data detailing the payments over £25,000 made by BDUK on behalf of the Department for Culture, Media and Sport (DCMS).
It means the figures do not consider smaller payments or mobile and spectrum related costs.
BDUK is mainly responsible for overseeing the £1.7 billion public rollout of fixed line superfast broadband (24Mbps) services to 95% of premises by 2017.
According to ISPreview, the £5.041 million spent on marketing was given a major boost in December 2014 through the release of a new government television advertising campaign, which helped to inspire a more aggressive push to generate awareness.
While there is a feeling that the amount spent on advertising is significant, the main driver has been the pursuit of increased upgrades.
The investment has already reportedly found some level of success, with the clawback reinvestment mechanism returning up to £129 million to increase coverage.
