Stromberg became an editor of "The Sun", the major daily newspaper in Baltimore, , which would coincidentally absorb "The Times" and its last independent owner, the Patuxent Publishing Company of Columbia, Maryland along with the later community suburban newspapers in a later merger and take-over of Stromberg's Patuxent Publishing successors, in the early 2010s. With Judge James A. Clark, Sr., Paul Talbot and himself as editor in 1920, they took over control of the "Howard County Times", which had been founded in 1840 and had a long distinguished record of publication. Beginning in 1940, Stromberg took control of the Maryland Printing and Publishing Company which gave him sole ownership of the "Howard County Times" paper. Stromberg in turn created or purchased eleven new local papers in central Maryland and the surrounding suburbs of Baltimore County during the 1950s and 60s and employed his stepson Charles L Gerwig as editor. In January 1940, his newspaper business nearly was halted by an Ellicott City fire in the building hosting Melville Scott and Sons insurance and the post office which netted $3,000 in insurance settlements. The same year, Stromberg was appointed as the head of a five county commission to propose a military "Super Highway" between Baltimore and Washington. In 1944, he became the President of the Maryland-Delaware-District of Columbia Press Association (MDDC Press Association). Stromberg's editorial influence helped his brother-in-law Norman E. Moxley become a County Commissioner and member of the Howard County Board of County Commissioners in 1949, Edgar Russell Moxley to become Police Chief, and Robert Moxley a prominent land developer purchasing land for the Rouse Company and nationally famous mall developer James Rouse, (1914–1996), who began laying out and development of the new town of Columbia, Maryland in the central part of the County, midway between Baltimore and Washington, D.C. in 1967.
