What is White House Correspondents' Dinner?

Some information about White House Correspondents' Association Annual Dinner(WHCA-Dinner):::

This a former image of WHCA.. Which is turned 100 years this year. 

Let's See what WHCA website says:

Legend has it that reporters first took up a daily beat inside the White House one frigid day in the early 1900s, after President Theodore Roosevelt noticed a band of correspondents staking out sources in the rain. The president "looked out and took pity," as one chronicle of the period reports it.
But historians have since debunked that simple version of events, offering instead a richer tale about how reporters worked their way into the White House and then slowly expanded their presence over the years.
In fact, the rise of the White House beat is "an evolutionary portrait," says Martha Joynt Kumar, a Towson University political scientist on the presidency and the press. She has charted the way the White House press worked its way up from huddling over one small table in the mansion to occupying a full press room in the West Wing.
A press corps of some 250 people now keeps a daily watch on the administration, relying heavily on their proximity to the president and his staff inside the walls of the historic building.
This year, the White House Correspondents' Association marks the 100th anniversary of its 1914 founding to advocate for reporters on that historic assignment. The group has grown and expanded its activities, in 1920 launching a spring dinner that now merits news coverage along with a yearly appearance by the sitting president.
The journalists of today's WHCA share the spirit of those early forerunners, pushing for access to the president and members of the administration amid the challenges of a modern media landscape.
As the association marks its anniversary this year, veteran White House reporters, political journalists and scholars will chart the story of that evolving group of professionals in a series of blog posts on this website. The year-long series is being produced in cooperation with the White House Historical Association.
Today, the WHCA represents each sector of the media filling the press room each day. All trace their roots back to the newspaper reporters who, in the 1890s, stood outside the White House fence to seek meetings with the president and to question visitors as they left the grounds.
Contrary to the discredited legend, a hardy corps of reporters had actually been working the beat from inside the White House for years before Roosevelt even took office.
In fact, two administrations prior to Roosevelt, a group of correspondents already had their own table inside the building. A Washington Star reporter by the name of William W. Price –- who became the first president of the WHCA -- referred to it in a letter to the staff of President Grover Cleveland.
Administration officials under President William McKinley further expanded the area where reporters could roam. By the time of the Spanish-American War, journalists had pushed their way in so far that they could be found sitting about on the porch, in the front lobby and on the landings, according to accounts of the time.
"With their own observed territory," Kumar writes in a paper on the history of the beat, "reporters established a property claim in the White House."
Every generation of reporters since has pushed to build on that right, pressing for briefings, interviews and regular coverage of the president's public activities by a rotating group of representatives called "the pool."

We'll bring you their stories, here, as the centennial year unfolds.
