U.S. advertising expenditure data

U.S. advertising expenditure, for various media and type categories across the years 1919 to 2007, is now available in a dataset convenient for extensive analysis. These data quantify the rise of advertising on radio, on television, in telephone directories (yellowbook), and on the Internet.  They also quantify less widely discussed media for advertising, such as direct mail, billboards and outdoor advertising, and advertising in business papers (trade press).  You can, of course, also create your own categories, such as ad expenditure totals relative to GDP.  Advertising is widely regarded as an important aspect of new media businesses.  This dataset is meant to inform thinking in this time of dramatic changes in the communications industry.

The advertising expenditure data mainly come from Robert J. Coen, now at Magna in the McCann Erickson advertising agency.  Coen has worked for decades putting together advertising expenditure figures.   His advertising data were published in the U.S. Census Bureau’s Historical Statistics of the United States, Colonial Times to 1970 (see pages 855-7).    The Television Advertising Bureau has made available online a recent version of Coen’s data covering the years 1948 to 2007.   I’ve augmented that data with Coen data for 1919 to 1947, previously made publicly available on the Internet.  In addition, I’ve added some categories of advertising expenditure for 1919 to 1934.  These additional figures are based on some Coen data, some data from other sources, and my own estimates.  In recognition of Coen’s work, I’ll call the dataset the “Coen Structured Advertising Expenditure Dataset,” or the “CS Ad Dataset” for short.

The CS Ad Dataset includes various advertising expenditure categories and aggregation schemes.  These are described in the CS Ad Dataset “categories” and “schemes” sheets.  Separating advertising into national and local advertising is possible from 1935.  The category “Television” was divided into “Broadcast TV” and “Cable” in 1990.  The category “Out of Home” replaced the category “Billboards” in 2000, with the former encompassing about three times as much expenditure as the later.  Categorization has become more specific over time.   In 1935, about 20% of advertising expenditure fell within a “Miscellaneous” category.  By 2007, the share of “Miscellaneous” was down to 13%.   To deal with issues of categorization and aggregation, the CS Ad Datset includes records containing the year, two levels of categorization, an aggregation scheme code, and the associated advertising expenditure for all years and categories from 1919 to 2007.   This data structure facilitates analysis using a relational database such as Microsoft Access.  If you don’t have such software, you can extract relevant data by re-sorting, cutting, and pasting as best suits your needs.

The quality of the advertising expenditure data merits further analysis.  Since Coen has long worked for an advertising agency, Coen’s employer has particular interests that might bias the data.  However, Coen has made the advertising expenditure data widely available for a long time.  Public exposure greatly increases the credibility of the data.

Some advertising expenditure figures have been revised over time.  Between 1975 and 2000, the total advertising expenditure figure for every year prior to 1940 were revised by more than 1%, with the figures for the 1920s revised downward about 15%.  Detailed categories changed more that the totals.  For example, totals between 1935 and 1945 were revised by less than 1.8%, while there was a -6.3% revision for magazine advertising in 1938, and -5.5% to +8.2% in the miscellaneous advertising figures.  Putting aside the most recent year of data, the largest revision to total advertising expenditure for post-WWII years was a 2.5% increase for 1998.  This revision occurred between 2003 and 2008.   The “revisions” sheet in the CS Dataset shows some revision history for the total figures.  Overall, data other than the most recent year appear to be reasonably stable.   Nonetheless, since revisions are ongoing, dating the Coen data used is important for consistently defining figures.

The Newspaper Association of America (NAA) lists mainly Coen data on its website under a page-tab “annual ad volume” (all-media table).  The NAA, however, inserted its own estimates of advertising expenditure in newspapers, an area of advertising for which the NAA has a particular interest. The NAA newspaper advertising expenditure in its all-media table doesn’t respect the over-all aggregation scheme of the data.  Specifically, the NAA newspaper advertising figures include online newspaper advertising, while Coen has a separate category for Internet advertising.  For details, see the “NAA Comparison” sheet in the CS Ad Dataset.  In addition, while the NAA inserted its own newspaper advertising expenditure figures, it did not change other Coen figures to account for this change.  Hence the total figures for the NAA all-media table don’t add up.  The NAA table also seems to include different revisions of Coen’s figures.  Hence the NAA all-media table is’t a good quality source for consistent, historical advertising expenditure data.

Note: The CS Ad Dataset is available online and as an Excel workbook.  See also additional discussion of ad expenditure.

Update: For some additional comparative advertising expenditure data from the U.S. Census Bureau, see U.S. advertising expenditure, 1998-2007.   Here’s a review of alternate advertising expenditure data, including IRS data on advertising.

  1. This is an incredibly helpful and valuable project to make available to all of us who work, study, and live in the media and advertising business. Thank you for your time and dedication put into compiling this data. Special thanks as well to extraordinary work of Robert Coen.

  2. I have been searching around for a while trying to find comparison data across channel. This is exactly what I have been looking for — and more. Thanks very much to you and Robert Coen for providing.

  3. Thank you SO much for making this available. I have been scouring the internet for this. You broke everything down into sections, which serves my purposes perfectly.


  4. Thanks so much for doing this. Saves a ton of work.

    One nit: the 1911 number on the summary sheet seems to be missing a zero.

    On the internet numbers: Coen seems close to the TNS numbers. I’ve been told these are display ad only numbers. The IAB is IAB number is display, search, email, lead generation and classifieds. I think you’re right, though, that changing these would mean decreasing something else. (The IAB, like the NAA, is also not necessarily the most objective source.)

  5. Thank you for these helpful data. However, it does not say anything about Coen’s methodology. Is he doing surveys? Do you know how he actually generates his data?
    Best regards!

  6. Hi there,

    Thanks for this helpful data! One question: are the categories mutually exclusive? I.e. does the “newspaper” category include internet-based newspapers? Or are those captured entirely by the “Internet” category?


  7. Why does this data end in 2007? Looking at old Ad Age magazines, it seems that Coen used to update this frequently. Is there any reason that he stopped?

    1. Coen retired by early 2009. That hardly gave him time to produce data for calendar year 2008. But if you find 2008 data published in Ad Age, please forward it to me and I’ll add it to the dataset.

      1. The best I have found is the graph below which contains some 2009 and 2010 estimates (noted under the graph). I have been looking for data from recent years to analyze the effects of the internet. If I find anything else I will definitely send it along.


        By the way, this dataset is a great resource for my research and is very interesting. Thank you for making it available in such a useful format.

  8. This dataset is a great resource! Thank you for putting it together!

    A question: the spreadsheet indicates that “grand total” US advertising data is in current dollars. To which year does “current” refer? And how were they indexed (e.g., CPI, ad-pricing, etc.)?

    1. All the figures are in U.S. dollars, not adjusted for inflation. That’s what I meant by current. Thanks for identifying the confusing terminology, which I’ve corrected.

  9. Hi! Thank you for your great work, it’ll help me a lot for my master thesis!

    Also, would you happen to know where i can find the same data for the Eurozone?

  10. Hello Douglas,

    Firstly, great article and thank you for including links to the Coen’s data sets as well as an overview of his methodologies. That info has been a great help! I’m currently researching the variances between Coen’s figures and the figures reported annually by Kantar Media and had a question for you.

    In your research of Coen’s data, have you seen notes or comments describing how he defined his subcategories? For example, “Local Newspapers data is based on X# Local Publications” or “Internet is based on X sources”. In your article, it sounds like Coen also added Online Newspaper/Magazine data into his Internet totals, but I can’t seem to find as references for the definitions he used for his categories.

    1. I haven’t seen any definitions of Coen’s categories or sources. Coen worked for ad agencies. His sources seem to have been a variety of industry advertising sources. Looking at the ad industry trade press (e.g. Advertising Age) over time might give you additional insight.

    1. As far as I know, no one had updated the data. I doubt that it would be feasibly to update it, because many of the media categories and advertising data sources have changed.

  11. Dear Douglas,

    It seems the Google Spreadsheet link is no longer working! Could you please repost it? It would be so helpful!

    Thank you,


    1. All the links should be working now. If not, please describe more specifically which link isn’t working. The data are also available the data as an Excel workbook. You can open that in Libre Office if you don’t have Excel.
