Assume barriers to entry in news provision have declined because internet news sites are less costly to set up than old fashioned newspapers and magazines. According to some observers, news companies have grown more polarized in the past decade, in that left/right-leaning news providers became more ardently leftist/rightist and more fervent in negatively skewing discordant news. Considering private sector news companies (i.e. not the CBC). Assuming customers, shareholders, news corporation employees and news corporation top executives are fully rational (the customers just have different tastes in politics), explain how increasingly one-sided news coverage could be a share-price maximizing strategy? Please provide a detailed answer in as many words as possible. Thank you
