Where can I find information about the advertising expenditures of different companies?
A great resource for information about advertising expenditures and the advertising industry more generally is Red Books. This tool provides information about advertising agencies as well as advertisers (companies, non-profits, etc.). Data detailing total ad spending by a firm as well as the types of ads purchases (network TV, cable TV, Internet,etc.) can be found in Red Books. You can get access to Red Books by going to this link to the Pomerantz Library Databases A-Z list.
