of professional concepts - such as off-record, objectivity, and balance - amongst those who produce their own media. Some argue that ordinary citizens may do more harm than good if they are able to publish their personal thoughts and opinions and pass them off as legitimate journalism. The following are ways that citizen media negatively differentiates from traditional journalism, according to critics: Bias can be a problem in citizen media because there are multiple steps traditional journalists must undergo before publishing, such as waiting for confirmation before reporting a story. These steps do not always carry over to citizen media publication because they are not affiliated with any entity that would have additional editors. This can result in a lack of accountability and a strong presence of personal bias. Transparency is another point of criticism. In citizen media, the user generating the content is often anonymous, hidden by a username. In traditional media, the reporter or editor's identity is known and can be identified by their byline. Conversely, there are some forms of citizen media, in which the author is known; this is most often in blogs. Modes There are many forms of citizen-produced media including blogs, vlogs, podcasts, digital storytelling, community radio, participatory video and more, and may be distributed via television, radio, internet, email, movie theatre, DVD and many other forms. Many organizations and institutions exist to facilitate the production of media by private citizens including, but not limited to, Public, educational, and government access (PEG) cable TV channels, Independent Media Centers and community technology centers. Print Zines are an example of citizen media. According to Barnard College, there are various definitions for zines, but they share the following features: "self-published and the publisher does not answer to anyone; small, self-distributed print run; motivated by the desire to express oneself rather than to make money; outside the mainstream; low budget." Zines are self-published and free of any responsibility to an internet service provider, as blogs are. As a result, creators are able to bypass traditional journalism guidelines, such as copyright and ethical considerations. Radio World Wide Community Radio has been driven by participatory methodologies with rich examples of community radio providing a non-profit community owned, operated and driven model of media. The Public Broadcasting Service (PBS) in the United States initiated by the Public Broadcasting Act of 1967 sets aside some public broadcasting funding for producing electronic television
