A Writer's Guild of America report argues that Disney, Netflix and Amazon have used their growing size and industry clout to undercut writers, detailing how media and tech companies have consolidated power through mergers and acquisitions, and called on government regulators to put a stop to it. The guild also contends that streamers like Netflix pioneered business models that reduced the pay of writers and were later adopted by other, more traditional companies, including Disney. The WGA report makes the case that vertical integration, which is when studios make content for their own distribution platforms, has hurt writers and will get only worse if it continues. In addition, The "Netflix Effect" is a phenomenon where people, including children, lose track of time while binge-watching television series. The urge to discover what happens next is emotionally overwhelming. The Netflix Effect can have negative consequences for children, including loneliness and depression, disrupted functioning and anti-social behavior.
