Search figures released by Google this week have shown that Cameron has overtaken Brown as the topic of Google searches for the first time since last year.
The research also revealed that Nick Clegg was a less searched for phrase than "hung parliament". Searches for this phrase saw a massive 233 per cent on the week before.
The Tories have been a good deal more active in terms of utilising Google AdWords as well as arguably having the largest presence on social networking sites such as Facebook and Twitter.
David Cameron saw Google searches on his name jump by 163 per cent last week, putting him ahead of Mr Brown, who saw searches spike 92 per cent. Despite Nick Clegg's name having the biggest increase, up 426 per cent, he still remains in third place in terms of most searched for leader.
Although average polling figures last week put the Tories on a 6-9 point lead of over Labour,
the opinion polls are still forecasting that no party will attain overall control of the House of Commons.
The Digital Economy Bill, which passed into law last week, saw searches rise by 614 per cent after many protests, both on and offline about its propsed punishments for those found guilty of internet piracy. According to the BBC news, the bill briefly overtook searches for Afghanistan on Google.
