Broadside is a
large sheet of paper printed on one side only, often containing a song or ballad,
and sold by wandering pedlars in Britain from the 16th century until the beginning
of the 20th century, when they were superseded by mass-circulation newspapers;
they also appeared in the USA in the late 19th century. The broadside ballads
were intended to be sung to a well-known tune; often they related topical
events, and some were adopted as folk songs. Broadsides are sometimes
called broadsheets.
