It really happened, and it happened on Twitter (TWTR) - Get Report  and Facebook (FB) - Get Report.

Donald Trump, the former reality-TV star, much maligned by the Republican Party even as he captured its nomination and defeated Hillary Clinton, was inaugurated Friday as the 45th U.S. president.

And befitting a candidate who fueled his meteoric if incendiary campaign through a storm of tweets, Twitter carried the inauguration live in a partnership with the PBS News Hour, a news organization that gets about 15% of its funding from the government.

The Twitter live stream began at 11 am ET and will run to 5 pm. And reflecting the extremes of both euphoria and angst hanging over this day, and weekend, the feed, also available at @NewsHour was a running dogfight between the Republican's supports and detractors.

Broadly speaking, website traffic on news media sites within the U.S. spiked 80% spike at 12:01 p.m. New York time just as Trump began his speech, according to Fastly, a content-delivery network. Through the inauguration, traffic was 232% higher than for the same period a week ago, Fastly said in an e-mailed statement. Internationally, Trump's speech triggered an immediate 89% spike in traffic at news web sites, and a similar 217% increase from a week earlier.

As part of the transfer-of-power, Twitter also arranged a peaceful passing of handles:

Trump takes @POTUS with Obama assuming @POTUS44. Same goes for @FLOTUS and @FLOTUS44 as well as @WhiteHouse and @ObamaWhiteHouse. All previous Obama tweets will move over to the new handles.

Meanwhile, Facebook didn't live stream the inauguration but its Live platform appears poised to become the platform of choice for the incoming administration.

On Thursday night, Dan Scavino -- who's going to head social media efforts in the White House -- posted a Facebook Live video of the president-elect getting on a plane in New York for the short flight to Washington. That 45-second video quickly garnered 1.8 million views. And at Trump's first press conference last week, spokesman Sean Spicer noted that the president-elect's Facebook Live stream received 4.2 million views

Spicer said on Thursday that "...when you look at it in the context of a lot of media outlets, [4.2 million views] is a pretty stunning figure to talk about the breadth and depth of what he is able to capture on not just Twitter but clearly on Facebook and other social channels."

On Friday morning, shots of Republican leaders and soon-to-be former President Barack Obama were woven around appearances of the America's Got Talent competitor Jackie Evancho, the Mormon Tabernacle Choir and New York City's The Rockettes, the dance troupe that wasn't particularly unified about participating the event.

Not to be outdone, NBC News, a unit of Comcast (CMCSA) - Get Report , also began streaming the inauguration beginning at 10 am, as did 21st Century Fox's (FOXA) - Get Report Fox News, on its website and app. CBS (CBS) - Get Report  had all events on its broadcast channel as well as CBSN, its online platform. And for those looking for a somewhat more critical view, Democracy Now! provided a livestream as well.
