Online Journalism refers to the dissemination of information through the aid of the internet. Just as the words imply: online means to be available over the internet while journalism is the profession of reporting, photographing or editing news stories for one of the media channels.
Hence, this implies that news information and every other activity performed by a media house is done on the internet.
However, it should be noted that using internet for journalism does not relegate the relevance of the traditional media (print and broadcast). Instead, online journalism should complement the traditional media practices.
