What was the name of the New York magazine Poe co-owned and edited in 1845?

The New York magazine Edgar Allan Poe co-owned and edited in 1845 was the Broadway Journal.

Founded in 1844 by Charles Frederick Briggs and John Bisco, the Broadway Journal began publication in New York in January 1845. Poe joined as an editor in February, agreeing to contribute original writing and receiving a share of the profits.

Poe gradually gained greater control. Briggs resigned in June 1845 because of financial difficulties, and in October Bisco sold his share to Poe for $50. Poe then held full ownership and editorial control, making the journal the only periodical he ever owned.

The magazine published Poe's poems, stories, and literary criticism, including material connected with The Raven and his controversial attacks on writers such as Henry Wadsworth Longfellow. Despite Poe's hopes of making it successful, the Broadway Journal ended with its final issue dated January 3, 1846.
