Does "network radio and television" in the following text mean simply radio and television channels or internet-based radio and television?
Context:
The vast network of global media, including print media, television, and the internet, is another key component of contemporary globalism. This network cements large US, European, and Japanese corporations’ control of the release and dissemination of information, one outcome of the deregulation of network radio and television in these countries. This deregulation began in the US in the 1970s and was mostly enacted during the Reagan administration in the 1980s, when the Federal Communications Commission’s regulatory power was considerably curtailed (source).
