In the usual "Read Only" media culture, the culture is consumed more or less passively. The information or product is provided by a 'professional' source, the content industry, that possesses an authority on that particular product/information. There is a one-way flow only of creative content and ideas due to a clear role separation between content producer and content consumer. The emergence of Analog mass production and duplication technologies (pre-Digital revolution and internet like radio broad-casting) inherently enabled the RO culture's business model of production and distribution and limited the role of the consumer to consumption of media.
