Media & Marketing Online targets people working in advertising, marketing, public relations, media and entertainment. The site will provide round-the-clock news coverage of the sector, written by Wall Street Journal and Dow Jones Newswire journalists.
The site will carry features only available to WSJ Online subscribers, a column on the business of TV written by veteran WSJ media reporter Joe Flint, and a daily analysis piece.
Stories will be taken from the US, European and Asian editions of the paper.
Todd Larsen, president of Dow Jones Consumer Electronic Publishing, said: "Media and entertainment corporations today span the globe with their programming, and advertising and public relations agencies are operating units of global holding companies."
He added: "Genuinely informed coverage of these industries requires a global perspective, and that's what we will provide with stories from The Wall Street Journal's US, European and Asian editions, as well as the worldwide bureaus of Dow Jones Newswires."
Subscribers to the media and marketing edition will get the full contents of the Wall Street Journal Online. Its subscription charge will be the same as the WSJ Online's $79 (£50.40) annual charge or $39 a year for subscribers to the print journal or Barron's.
Existing Wall Street Journal Online subscribers will automatically get access to the new service when it launches.
