What is Byline?

Legal Definition
The byline on a newspaper or magazine article gives the date, as well as the name of the writer of the article. Bylines are commonly placed between the headline and the text of the article, although some magazines (notably Reader's Digest) place bylines at the bottom of the page to leave more room for graphical elements around the headline.

The dictionary defines a byline as "a printed line of text accompanying a news story, article, or the like, giving the author's name."
