Editor's note: Today, Ad Age is launching our 2016 Presidential Campaign Ad Scorecard, a comprehensive view of spending across broadcast, cable and satellite TV as well as radio. The charts you see below represent a collaboration between Ad Age's Datacenter and Kantar Media's Campaign Media Analysis Group (CMAG). Unlike a previous story that looked at the FEC filings of only the candidates' campaigns, this scorecard considers the campaigns and the PACs that are supporting them.
Each Friday, we'll serve up fresh CMAG data parsed by Datacenter Director of Data Management Kevin Brown and made beautiful -- and interactive -- by Digital Content Producer Chen Wu. Kate Kaye, our data and analytics reporter, and Simon Dumenco, aka Media Guy, will be offering insights on the ad spending race both in this space and elsewhere in our continuing Campaign Trail coverage. --Ken Wheaton
