In the final days of the presidential race, ad spending is closing in on $1 billion.
The campaigns and outside groups have combined to spend $968 million, according to NBC News/SMG Delta.
An unprecedented $143 million has been spent this week, far-and-away a record for this presidential cycle -- with more ads already being booked today.
Team Romney, including the campaign and groups supporting the Republican challenger, are outspending Team Obama $96.4 million to $46.2 million this week. Accounting for this massive spending disparity, there are 11 outside groups pitching in to support Romney this week while just two are doing the same for Obama.
But despite the massive spending advantage Team Romney is enjoying over Team Obama, they are about even in ad points, according to SMG Delta. In other words, they are running about the same number of ads.
That's because the Obama campaign booked advertising well in advance, as compared to the Romney campaign which makes buys days -- sometimes the day -- before. Outside groups also have to pay more than campaigns for their ads.
Overall, Team Romney has outspent Team Obama $573.2 million to $394.4 million in this election.
The vast majority of outside money has gone to support Romney. In fact, 85 percent of all outside money poured in during this campaign has gone to support Romney or oppose Obama.
Nearly two-thirds -- 63 percent -- of all the money going to support Romney has come from outside groups. By contrast, just 16 percent of the money supporting the president has come from outside groups.

Pro-Romney: $363 million
Pro-Obama: $63.5 million
