The newspaper was established in 1889 by William W. McMurray, a pioneering journalist in the then-Wyoming Territory.[2] In its early years, the Star competed with several other local bulletins during the region's coal mining and railroad boom. By the mid-20th century, it solidified its position as the primary news outlet for the county seat. In the mid-20th century, the paper underwent several ownership changes. John Rhea Jacobucci, a notable figure in Wyoming politics and business, served as the editor starting in 1936.[3] In 1968, the publication was purchased by Sage Publishing, which expanded its distribution and modernized its printing operations.[4]
Throughout the 2000s, the paper transitioned to a digital-first model while maintaining its Wednesday print edition.[5] In 2021, the newspaper's reporting on local law enforcement transitions received recognition from regional press associations.[6]
The Green River Star covers municipal proceedings of the Green River City Council and the Sweetwater County Board of County Commissioners. It also provides coverage of the Sweetwater County School District #2.
The paper is currently owned by Sweetwater Now, following an acquisition aimed at consolidating digital and print local news assets in the region.[7]
While many regional competitors faced closure in August 2025 due to shifts in the ownership strategies of out-of-state media conglomerates, the Green River Star continued its operations.[8] Following cut backs in printing of its longtime rival, the Rocket-Miner, the Star became the largest circulated print newspaper in Sweetwater County. In late 2025, the newspaper expanded its coverage to include more county-wide reporting to fill the gaps left by defunct publications.[9] It currently maintains a physical office at 445 Uinta Drive in Green River.[10]
