Sapolio

Sapolio was a brand of soap noted for its advertising, led by Artemas Ward from 1883–1908. Bret Harte wrote jingles for the brand, and the sales force also included King Camp Gillette, who went on to create the Gillette safety razor and the razor and blades business model. Time magazine described Sapolio as "probably the world's best-advertised product" in its heyday.
Sapolio was manufactured by Enoch Morgan's Sons Co. in 1869 and was named after the family doctor.
James Kenneth Fraser, a copywriter and Cornell University engineering student, wrote in 1900 about the effectiveness of the soap in ''The Doctor's Lament:''

Decline and disappearance

After decades of maintaining some of the best-known advertising in the U.S., Sapolio's owners decided that their position was sufficiently insurmountable to let them discontinue most advertising. Despite the brand's overwhelming market position, it was overtaken by competitors within a few years and disappeared before World War II.

Revival

After the brand Sapolio disappeared, it remained under the domain of Enoch Morgan's Sons Co. until, after some negotiations, it was acquired by Procter & Gamble. However, they did not decide to relaunch the product until many years later, leaving the brand abandoned.
In 1997, the Sapolio brand was acquired by the Peruvian company Intradevco Industrial SA, who bought it from Procter & Gamble. Intradevco owns the Sapolio brand in more than 80 countries. The Sapolio brand now markets various cleaning products in Peru and Chile.
The Intradevco company also bought its Chilean counterpart Klenzo, which held the Sapolio patent in Chile.
In 2019, the Alicorp company bought the rights of Intradevco, which owns Sapolio, making it its parent company.
