Ballyhoo! presents a concise history of advertising posters and their use of celebrity in the United States, as well as the export of U.S. celebrity to other countries. The website was initially created as an accompaniment to a National Portrait Gallery exhibit which ran in 2008 through 2009.

The site is broken down into an introduction and eight short explanatory sections, each with a two-paragraph essay and four to eight related posters to view. An additional lesson plan, designed for 5th- through 12th-graders, includes a worksheet guiding analysis of historical posters, as well as a poster-making activity.
