How Donald Trump uses social media to market
The recent news on campaign ad spending is not good for television networks, usually bolstered by an arms race between candidates.
Trump campaign has spent $17.3 million on election ads, according to data from NBC partner Advertising Analytics.
Clinton's campaign, on the other hand, has spent an estimated $96.4 million so far in ads in general election ads.
Add in ads from outside groups, and Clinton's number balloons to $156.6 million versus $33.6 million for Trump.
But the Trump campaign and other parties has raised around 50% less than Clinton.
