All Messenger titles feature regular sections such as lifestyle, Vibe (entertainment guide), Sport, and Your Garden.
The Adelaide Advertiser, Sunday Mail and various other News Ltd publications are also based in Sir Keith Murdoch House.
In 1959, Baynes' fellow courier, Ron Mitchell, joined Messenger to run its newest acquisition, the Standard.
In the 1970s and 1980s, newspapers in the Adelaide Hills, south coast and Barossa Valley were added to the Messenger stable.
In 1981, the firm purchased a Mitsubishi L600 colour press, enabling Messenger to print coloured magazines including The Advertiser Magazine, Football Times, South Australian Radio TV Extra and Adelaide Matters.
In 2007, Messenger Newspapers began publishing news online and uploaded web videos for the first time.
The newly launched publication now takes in North Adelaide, which was previously covered by The City Messenger.
The City North was launched with a new emphasis on increased coverage of news, sport and lifestyle content.
