About the IAB Internet Advertising Revenue Report
Conducted by PricewaterhouseCoopers LLP on an ongoing basis, with results released

advertising revenues from Web sites, commercial online services, ad networks and e-mail
providers, as well as other companies selling online advertising.
The report is conducted independently by PricewaterhouseCoopers LLP on behalf of the IAB.
PwC does not audit the information and provides no opinion or other form of assurance with

4. Executive Summary
IAB Internet Advertising Revenue Report
2009 Full Year Highlights
Internet advertising revenues (―revenues‖) in the United States totaled $22.7 billion for the full year of 2009,
with Q3 2009 accounting for approximately $5.5 billion and Q4 2009 totaling approximately $6.3 billion. Internet
advertising revenues for the full year of 2009 decreased 3.4 percent over 2008.
Key trends underlying 2009 results
 Revenues Decreased 3.4% in 2009 — Internet advertising revenue in the U.S. totaled $6.3 billion in the
fourth quarter of 2009, an increase of 13.8 percent from the 2009 third-quarter total of $5.5 billion, and an
increase of 2.6 percent from the 2008 fourth-quarter total of $6.1 billion. Full year Internet advertising
revenues of 2009 totaled $22.7 billion, down 3.4 percent from the $23.4 billion reported in 2008.
―The record $6.3 billion spent on internet advertising in the fourth quarter of 2009, while certainly aided by
seasonal demand, is a strong indication that the worst of the economic impact on internet advertising is over
and that the seeds of growth have been planted.‖
—David Silverman, Partner, PricewaterhouseCoopers LLP
 Search Continues to Lead, followed by Display Banners and Classifieds—Search revenue accounted
for 47 percent of 2009 revenues, up from the 45 percent reported in 2008. Display advertising also showed
solid growth, accounting for 35 percent of 2009 revenue up from 33 percent in 2008. Digital video, which is
a component of display advertising, increased 38 percent from 2008 to 2009.
―This IAB Internet Advertising Revenue Report makes clear that digital media are now a core component of
successful advertising and marketing campaigns,‖ said Randall Rothenberg, President and CEO of the IAB.
―As consumers spend more of their time immersed in digital media, marketers are increasingly reaching
them there--building brands online and making digital the central force in their cross-media strategies.‖

17. Definitions of Advertising Formats
Display Advertising (Banner Ads)—advertiser pays an Internet company for space to display a static or hyper-linked
banner or logo on one or more of the Internet company’s pages.
Sponsorship—represents custom content and/or experiences created for an advertiser which may or may not include ad
elements such as display advertising, brand logos, advertorial or pre-roll video. Sponsorships fall into several categories:
 Spotlights are custom built pages incorporating an advertiser’s brand and housing a collection of content usually around a
theme;
 Advergaming can range from an advertiser buying all the ad units around a game or a ―sponsored by‖ link to creating a
custom branded game experience;
 Content & Section Sponsorship is when an advertiser exclusively sponsors a particular section of the site or email (usually
existing content) re-skinned with the advertiser’s branding;
 Sweepstakes & Contests can range from branded sweepstakes on the site to a full-fledge branded contest with
submissions and judging
E-mail—banner ads, links or advertiser sponsorships that appear in e-mail newsletters, e-mail marketing campaigns and
other commercial e-mail communications. Includes all types of electronic mail (e.g., basic text or HTML-enabled).
Search—fees advertisers pay Internet companies to list and/or link their company site domain name to a specific search
word or phrase (includes paid search revenues). Search categories include:
 Paid listings—text links appear at the top or side of search results for specific keywords. The more a marketer pays, the
higher the position it gets. Marketers only pay when a user clicks on the text link.
 Contextual search—text links appear in an article based on the context of the content, instead of a user-submitted
keyword. Payment only occurs when the link is clicked.
 Paid inclusion—guarantees that a marketer’s URL is indexed by a search engine. The listing is determined by the
engine's search algorithms.
 Site optimization—modifies a site to make it easier for search engines to automatically index the site and hopefully result
in better placement in results.
Lead Generation—fees advertisers pay to Internet advertising companies that refer qualified purchase inquiries (e.g., auto
dealers which pay a fee in exchange for receiving a qualified purchase inquiry online) or provide consumer information
(demographic, contact, behavioral) where the consumer opts into being contacted by a marketer (email, postal, telephone,
fax). These processes are priced on a performance basis (e.g., cost-per-action, -lead or -inquiry), and can include user
applications (e.g., for a credit card), surveys, contests (e.g., sweepstakes) or registrations.
Classifieds and auctions—fees advertisers pay Internet companies to list specific products or services (e.g., online job
boards and employment listings, real estate listings, automotive listings, auction-based listings, yellow pages).
Rich media—advertisements that incorporate animation, sound, and/or interactivity in any format. It can be used either
singularly or in combination with the following technologies: sound, Flash, and with programming languages such as Java,
JavaScript, and DHTML. It is deployed via standard Web and wireless applications including e-mail, static (e.g. .html) and
dynamic (e.g. .asp) Web pages, and may appear in ad formats such as banners, buttons and interstitials. Interstitials are
included in the rich media category and represent full- or partial-page text and image server-push advertisements which
appear in the transition between two pages of content. Forms of interstitials can include splash screens, page takeovers and
pop-up windows.
Digital Video Commercials—TV-like advertisements that may appear as in-page video commercials or before, during,
and/or after a variety of content in a player environment including but not limited to, streaming video, animation, gaming, and
music video content. This definition includes digital video commercials that appear in live, archived and downloadable
streaming content.
