The Ohio Stove Company was incorporated in 1872, in Portsmouth, Ohio. The company was organized as a foundry to cast iron stove parts and assemble its line of coal heating and cooking stoves. In 1942 the company expanded into commercial gray iron casting to produce parts for the air conditioning, transportation and transmission industries. By 1953 the conversion from stove production to commercial casting was complete. All stove patterns were sold. The Ohio Stove Company changed its name to OSCO Industries, Inc., in 1972 on the company's 100th anniversary.
The Portsmouth Times Building was sold in 2016. Staff ceased working from the location. Production of the newspaper had moved to Gallipolis, Ohio, several years earlier. The Portsmouth Daily Times had operated out of the 637 Sixth (6th) Street location since 1955.
