What, then, are some of the trends that have affected our systemic processes of news production and consumption in recent years, rendering them vulnerable to (charges of) "fake news"? For one, there has been a significant acceleration of the news cycle. People no longer get their news once a day, in an aggregated form -- either in the form of a bundled-up morning paper or as a late-night news bulletin on TV. Instead, news outlets now compete 24/7 for their viewers' attention. Second, media markets have fragmented, not least due to the emergence of cable television in the 1980s, the rise of private TV channels and the gradual decline of bipartisan support for public broadcasters such as the BBC.
"bipartisan" means: of or involving the agreement or cooperation of two political parties that usually oppose each other's policies.
But here that makes no sense that two opposing parties used to support BBC. Does it mean that BBC used to be supported by all political groups generally?
