Wisconsin Advertising Project
Since 1998, the Wisconsin Advertising Project (WiscAds) has undertaken research initiatives to document how candidates, political parties and special interest groups communicate with voters. WiscAds studied campaign advertisements in the nation’s 100 largest media markets by collecting and analyzing all political advertisements aired on broadcast and cable stations. Database made possible via technology developed by the Campaign Media Analysis Group (CMAG), now contains information on the airing of over 1.5 million ads between 1998 and 2002, see The Data. Data needs to be requested through an online request form but historic ads can be freely viewed.
