"Sinclair Broadcast Group — a conservative, Trump-friendly television empire — is poised to become one of the most powerful players in the mainstream media. The relatively unknown company, whose stations have mixed conservative commentary with local news, is now on the verge of a deal that would allow it to reach nearly three-quarters of American households." 
Trump cleared the way for this propaganda coup by relaxing regulations broadcast ownership. This was on May 8,2017 after that Sinclair bought Tribune media company giving them 42 stations upon which to broadcast Trump propaganda. 
This move was only thought about when Guo's article was published lat year, since that time it has came to pass and Sinclair is now the nations largest fleet of tv news outlets. The empire is now 200 stations.  "So funny to watch Fake News Networks, among the most dishonest groups of people I have ever dealt with, criticize Sinclair Broadcasting for being biased. Sinclair is far superior to CNN and even more Fake NBC, which is a total joke," Trump tweeted. 
Sinclair has been criticized for the propagandist tone of it;s "news." The broadcast terrorist alert, right wing commentary, "classic propaganda and will reach three quarters of US households."Epshteyn’s softball interviews with administration officials and brusque commentaries are slavishly pro-Trump; a Baltimore Sun columnist wrote that the segments are “as close to classic propaganda as anything I have seen in broadcast television in the last 30 years.” The terrorism alerts serve no purpose other than to create a climate of fear. Pam Vogel of Media matters for America watched 200 such spots only to find:
Sinclair had all the anchors on all it;s stations read the same statement of propaganda, these have been collected and played at the same time so one can hear them all in uinision:
Conservative TV news giant Sinclair Broadcast Group wants its local viewers to be constantly petrified of an impending terror attack by Muslim immigrants and refugee...Terrorism Alert Desk segments actively reinforce far-right, xenophobic narratives about terrorism by almost exclusively focusing on stories involving Islam in some way, baselessly suggesting ISIS connections to breaking-news incidents, and providing vague soundbites with little information that nonetheless suggest that a “foreign” (brown, Muslim) terrorist lurks around every corner. They also cheer on law enforcement activity indiscriminately, hyping arrests even when suspects were later released without charges and obsessing over preventative security measures like bulletproof walls around the Eiffel Tower. In the absence of anything of quasi-substance to report, the segments resort to generalized fearmongering about things like ISIS graffiti being found in a New York subway station or even isolated, scary incidents that the reporters admit aren’t believed to be terrorism-related at all. After watching the more than 200 Terrorism Alert Desk segments that aired last year, I’m now sure these segments aren’t just the result of journalistic malpractice or sloppiness. They’re a tool strategically designed to make people feel constantly scared -- 
John Oliver made an hilarious video demonstrating the propagandist aspects,
This move of Sinclair's is an extreme is an extreme threat to our democracy. If one thinks "fake news" can't swing an election a new study shows it did, The 2016 election was swung to Trump because of his own fake news. While he is labeling real news media as "fake" he is dishing out propaganda garbage which of course is really fake news.
Researchers at Ohio State University, finds that fake news probably played a significant role in depressing Hillary Clinton's support on Election Day. The study, which has not been peer-reviewed but which may be the first look at how fake news affected voter choices, suggests that about 4 percent of President Barack Obama's 2012 supporters were dissuaded from voting for Clinton in 2016 by belief in fake news stories.Richard Gunther, Paul A. Beck and Erik C. Nisbet used three stories from the 2016 campaign and administered a huge questionnaire to 585 Obama supporters 23% of whom did not vote for Hilary, a quarter of the Obama supporters beloved at least one of the stories. Of those who believed the stories 45% voted for Clinton, for those who did not believe the stories 79% voted for her. Now I can see the methodological flaw in that there is no way to control for the chicken or the egg; did they believe the stories because their support was soft,or did they fail to vote for her because they believed the stories? But if we don't assume the stories bare some of the blame why do we we bother to campaign?
Local news is the most trusted source of information,according to Pew Research. 
Trump has been going after the media all the way, it's all fake, only he can be believed. The only valid sources of information are those that back him, Even when the facts are obliviously against him he is the only one to believe,This is just like every major dictator, the ministry of information is the propaganda arm of any dictatorship and Sinclair is setting up the Trump's ministry of information.This is a clear and present danger to our democracy:
The right reason to oppose this deal [media merger] is that Sinclair’s size and market dominance already threatens the open marketplace of ideas upon which our democracy depends. Allowing Sinclair to combine with another media giant would only make the threat worse.The merger that allowed Sinclair to buy the other stations is a dune deal. The only thing we can do now to block the effectiveness of Trump propaganda is to boycott Sinclair's stations, contact any group like Idivisable, or daily action or any resistance group and urge them to organize a boycott.see FN 7.
Sinclair is so large that it would have been illegal throughout most of the 20th century. Into the 1980s, the Federal Communication Commission (FCC) enforced strict limits on the number of broadcast stations that one company could own. The so-called “rule of seven” blocked any company from owning more than seven AM, seven FM, and seven TV stations.
