The US president has never been much of a bibliophile .

Despite not reading books regularly, President Trump gets his news the old-fashioned way: print media. According to Politico , his staff collects articles from newspapers ranging from the New York Post to the New York Times, and even prints out stories for him to read. President Trump likes to underline, star, and circle anything he reads.

To submit an article to the president, aides must run it through his staff secretary's office. If the article is approved, it gets added to a folder of other news stories, usually an inch or two thick.

Despite this, aides manage to sneak articles his way in case they won't be approved, despite former White House Chief of Staff John Kelly's attempts to shut down those unofficial channels.

No matter what Trump reads, it's often about himself. Reuters has reported that, when it comes to briefings, aides include the president's name as much as possible, "because he keeps reading if he's mentioned."

Mark Zuckerberg, unsurprisingly, starts his day on Facebook.

Facebook

In a Facebook Live session with Jerry Seinfeld , the Facebook cofounder and CEO tells the comedian that the very first thing he does in the morning, even before he gets out of bed to use the bathroom or puts in his contact lenses, is check his phone.

He says that he starts by looking at Facebook "I like to know what's going on in the world" and then checks his messages on Messenger and What'sApp. "On a good, calm day it'll probably take no more than a few minutes," he tells Seinfeld.

Jeffrey Immelt reads his papers in a very particular fashion.

"I typically read the Wall Street Journal, from the center section out," the former CEO told Fast Company . "Then I'll go to the Financial Times and scan the FTIndex and the second section. I'll read the New York Times business page and throw the rest away. I look at USA Today, the sports section first, business page second, and life third. I'll turn to Page Six of the New York Post and then a little bit on business."
