In 1922, Gomer Berry (later 1st Viscount Kemsley) bought the Sunday Mail, its sister paper the Daily Record, and another newspaper, the Glasgow Evening News, for £1 million.

He formed a controlling company known as Associated Scottish Newspapers Ltd.[3] Kemsley sold all three papers to the London-based Mirror Group in 1955.

In September 1999, when Editor Jim Cassidy was sacked, the paper's circulation was 767,000.

Its nearest rival was the Scottish edition of the News of the World which sold around 350,000 copies at that time.
