Republican presidential candidate Donald Trump has reportedly so far refused to invest in TV ads, with his TV ad spend paling in comparison to the supposed $61m spent on the slots by Hillary Clinton’s campaign.

NBC and its partner Advertising Analytics have released figures claiming Green representative Jill Stein and Libertarian candidate Gary Johnson have also spent more than Trump, $189,000 and $15,000 respectively.

However, the Wall Street Journal reports that Trump is poised to air his first TV spots starting on Friday in Florida, Ohio, North Carolina and Pennsylvania.

Trump’s reliance on his social media footprint, freely provided largely through his Twitter may prove to do more harm than good. 2012 GOP candidate Mitt Romney had spent $38m by this point in the cycle – still losing to Obama on the big night.

Trump’s advertising spend came to a halt in April after he picked up the primaries reports the Washington Post, hinting at a shift in strategy.

Democratic candidate Hillary Clinton was found to spend more on advertising in June alone that Trump did throughout May, June and most of April.

It’s worth noting you’ve probably seen Trump ads on TV, these have been largely paid for by PACs supporting the candidate – they’ve reputedly clocked up $12m in expenditure.
