He was also a pioneer, at developing pooled-asset partnerships. Among the first were papers in California, which included papers from Gannett Co. Inc., Stephens Media Group and MediaNews. Singleton's company contributed "Los Angeles Daily News" and the ANG operation, as well as other papers, while Stephens contributed papers such as the "Vallejo Times Herald" and the "Inland Valley Daily Bulletin" of Ontario. A year after forming the partnership, the duo allowed Gannett to enter, with its contributions including the "San Bernardino Sun" and the "Marin Independent Journal". The partnership is known as the "California Newspapers Partnership". MediaNews has entered into similar partnerships in Texas and Pennsylvania with Gannett and in Colorado with The E.W. Scripps Company.
