Porter and Tobin began publishing the Baltimore Price-Current and Weekly Journal of Commerce on June 29, 1850. In 1882, an industrial news and intelligence section was added to the paper, which was renamed the Journal of Commerce and Manufacturers Record. The Journal and Record were split that same year and continued to be edited and published separately. The Journal of Commerce and Price-Current was sold to and subsumed by the Manufacturers Record upon Porter's death in summer 1886. The Record continued publication until 1928.
