Scientific American

Scientific American is a civilian popular science magazine founded in 1845 in New York City, USA, by inventor Rufus Porter as a weekly broadsheet on inventions and industry. It is the oldest continuously published magazine in the US, transitioning to monthly in 1921. Key activities include interpreting scientific developments for lay readers, with many articles by researchers; it established the first U.S. Patent Agency branch in 1850 and advocated innovations like subways. Notable achievements: circulation grew to 30,000 by 1853, post-1948 revival under new ownership emphasized timeliness, now publishes 18 international editions. Owned by Springer Nature since 2015, it remains active, focusing on science journalism without direct involvement in UAP/UFO research or government programs.
