[4][5] On April 28, 1924, the Idaho State Journal began publication, but the Pocatello Tribune purchased that periodical in 1932.

However, due to the newsprint shortages during World War II, printing of the Idaho State Journal was suspended in 1942.

Like many others newspapers, the Idaho State Journal changed ownership multiple times during its early existence.

[4][5] The current Idaho State Journal became a reality on October 1, 1949, when it merged with another newspaper (the Pocatello Post), which had begun in 1947.

After several changes in operating sites, the newspaper moved to its current location on South Arthur Avenue in 1951.
