WASHINGTON (AP) - When President Barack Obama urged fellow leaders at the United Nations to do more for the world's refugees, his mention of a young boy named Alex could have been just a footnote, unnoticed or quickly forgotten.

WASHINGTON (AP) When President Barack Obama urged fellow leaders at the United Nations to do more for the world's refugees, his mention of a young boy named Alex could have been just a footnote, unnoticed or quickly forgotten.

The White House had other plans. Its social media specialists sent a video crew to the boy's home in New York. There they recorded an adorable Alex reading aloud a letter he had written asking Obama to bring to his house a 5-year-old bloodied boy the world had seen sitting in an ambulance in Aleppo, Syria. Young Alex promised: "We will give him a family, and he will be our brother."

When the White House posted the video on the president's Facebook page it was watched 27 million times. It also generated a wave of news stories around the country drawing attention to the boy's compassion and, by association, Obama's desire to persuade the United States and the rest of the world to embrace more Syrian refugees.

The Alex video demonstrates how the Obama administration has increasingly turned to a new menu of options to engage the public. The first American president of the social media age, Obama has for years been breaking ground on how politicians connect with a digitally savvy electorate. He has used social media as a tool to educate, to amuse, to spin and, undoubtedly, to shape his legacy. And judging by his successor's Twitter account, it's one of the few legacies he's leaving that President-elect Donald Trump has embraced.

The year Obama came into office, the White House joined Facebook, Twitter, Flickr, Vimeo, iTunes and MySpace. In 2013, the first lady posted her first photo to Instagram. In 2015, the president sent his first tweet from @POTUS, an account that now has 11 million followers. This year, the White House posted its first official story on Snapchat, a promotion of the president's State of the Union address.

White House officials say the focus on social media is simply a strategy of going to where people get their news. It's an add-on, not a replacement, they say, for press conferences and interviews with journalists. They say presidents, with very rare exceptions, can no longer rely on a single method for communicating their message.

"The biggest lesson that we've learned is that the bully pulpit is dead," White House Communications Director Jen Psaki said. "So we have a responsibility as a government and as his staff to come up with a range of ways and levers to communicate information."

The Pew Research Center recently found that about 4 in 10 Americans often get their news online. Digital is second only to TV news as the most prominent news platform. Younger adults are especially likely to turn to the web for their news.

Matthew Hindman, an associate professor at George Washington University, said presidents are increasingly closed off from the press, and Obama is no exception. Social media allows the administration not to be "hostage" to what the press is focused on during a particular day, he said.

"What this is about is getting their message out to their supporters, energizing the base, getting support for their policies, and to some extent shaping the agenda by forcing coverage of issues they think are important," Hindman said.

The American Presidency Project says Obama has held about 21 individual and joint press conferences a year during his presidency, fewer than his three predecessors. George H.W. Bush held about 34 a year, Bill Clinton averaged about 24 press conferences and George W. Bush, 26. Ronald Reagan, given the moniker the "great communicator," held about six a year.

Obama jokes about his social media skills, saying his cellphone doesn't allow him to make or receive calls and he can't text or take pictures. Basically, he can only use his phone to look at the internet and send emails.

"I now have an iPhone, but it is, you know, like, the phone you give your 2-year-old, where they can pretend to press things, but nothing actually happens?" Obama said on "Jimmy Kimmel Live."

Obama said in a recent interview for Snapchat's political show, "Good Luck America," that he wasn't up to speed on every aspect of social media when he ran for president.

"But I hired a bunch of 25- and 26-year-olds who were all into it," he said.

Obama has about a 15-person shop in the White House Office of Digital Strategy. Last year, he brought in Jason Goldman, who helped start Twitter, to run the operation. Goldman said Obama has a keen understanding of the power of social media, rising from the success of his 2008 presidential campaign.

"He clearly understood this was a way to reach people directly," Goldman said, "how they would emotionally engage with an issue."

To encourage that engagement early on, the White House set up a platform on its website in 2011 that allows people to petition the administration to take a certain action. If a petition can get 100,000 signatures within 30 days, the White House will provide a response. The administration more recently gave people the chance to send a message to the president through Facebook. The president reads 10 of these posts daily, prospective messagers are told.

Goldman said those functions fit with Obama's focus on "the imperative of citizenship," where input from citizens can help the government deliver better services.

"A lot of the things that we've done here will continue on regardless of what the next administration is," Goldman said.

Some media organizations have complained about the administration's reliance on social media. The Associated Press said in December 2013 that images posted on the White House Flickr page were "visual press releases" and were increasingly offered to the media in lieu of real journalistic access.

But the White House rejects the notion that its social media operations help the president bypass traditional media outlets.

"The goal isn't to be less filtered. The goal is to meet people where they are," Goldman said.
