Coldwell Banker Real Estate LLC announced The Letter, a national advertising campaign premiering on select Thursday evenings this fall during the 2026 football season on a streaming service. The campaign marks the Coldwell Banker brand's 120th anniversary and follows one family across three generations in the same home. Its 60-second centerpiece spans more than 30 years, while original 15-second spots focus on individual family moments, including dinner parties, holidays, graduations, visitors and new additions. The campaign was created with Siltanen & Partners and directed by Alice Gu. Production used actors cast at multiple ages, up to six hours of daily makeup to age or de-age them, evolving wardrobe and production design, and three cameras, including a 16mm film camera for the earliest period. Brandon Newman, Vice President of Marketing, Coldwell Banker Real Estate LLC, said the campaign focuses on the value of life inside a home rather than its financial or physical attributes. Mary Lee Blaylock, President of Coldwell Banker Affiliates, said the campaign's letter represents one family's transition out of a home while welcoming its next owner. The campaign forms part of the broader 120 Years of Home initiative, a full-year campaign about the role homes play in people's lives. Coldwell Banker says its network includes 93,000 affiliated sales professionals across 50 countries and territories, and that the brand has operated since 1906.
