Radio City Music Hall, one of the world's most celebrated and architecturally significant entertainment venues, opened in the heart of midtown Manhattan amid great fanfare on this day in history, Dec. 27, 1932. 

"Described as ‘the hottest ticket in town,’ more than 100,000 people requested admission (to opening night), but only 6,200 could be obliged," writes the website of the Radio City Rockettes, the iconic high-kicking dance troupe that performs at the theater.

"Radio City quickly became the favorite first-run theater for moviemakers and moviegoers alike. Before long, a first showing at the Music Hall virtually guaranteed a successful run in theaters around the country."

Landmark American films including "White Christmas," "Breakfast at Tiffany’s" and "To Kill a Mockingbird" — starring former Radio City usher Gregory Peck — are among the 700 movies that premiered at the theater over the decades.

The venue is better known today as the home of the Radio City Christmas Spectacular, the high-kicking Rockettes and a long list of iconic live performances throughout the year. 

It's also the home of a long list of superlatives.

"Radio City Music Hall is the largest indoor theater in the world. Its marquee is a full city-block long," boasts Madison Square Garden Entertainment, which purchased the venue in 2021.

"The stage is considered by technical experts to be the most perfectly equipped in the world. It is comprised of three sections mounted on hydraulic-powered elevators. They make it possible to create dynamic sets and achieve spectacular effects in staging." 

More than 300 million people have witnessed performances at the theater in the 90 years since it opened, according to MSG Entertainment. 

Radio City's Christmas Spectacular, a holiday highlight for millions of New Yorkers and tourists over the decades, was embroiled in controversy this month.

A mother escorting her daughter's Girl Scout troop to the Christmas show was booted out of the theater. 

Facial recognition technology identified her as an attorney working for a law firm embroiled in a dispute with Madison Square Garden Entertainment.

Radio City Music Hall's facade, with its signature glowing neon signage, makes it one of the nation's most recognizable urban and entertainment landmarks. 

It elicits "oohs" and "aahs" from countless tourists and selfie-takers each day. 

Radio City Music Hall is part of the larger Rockefeller Center development between Sixth and Fifth Avenues, which began in 1931 and was completed in 1939. 

It was a landmark achievement of urban renewal during the height of the Great Depression, remaking a seedy area of Manhattan once known as the "speakeasy belt."

Radio City was designed by architect Edward Durell Stone and interior designer Donald Deskey. 

Movie theater expert Samuel Lionel "Roxy" Rothafel serves as an adviser.

The Rockettes were known as the Roxyettes in Rothafel's honor from 1932 to 1934.

"The public areas of the music hall feature murals, sculpture and other work by prominent artists of the time. These interiors are considered some of the most impressive in the history of modern theater design, with no equal in America in terms of scale or variety of architectural, artistic and decorative elements," says the New York Preservation Archive Project. 

"As one of the principal achievements of the Art Deco style and as one of the finest theater designs in the country, the interior of Radio City Music Hall is of unique importance to the history of American architecture."

The Denver Broncos continued to clean out their coaching staff, announcing two more terminations after firing head coach Nathaniel Hackett on Monday. 

Special teams coordinator Dwayne Stukes and offensive line coach Butch Barry have also been relieved of their duties, the team announced. 

This was the first time of his coaching career that Stukes was a coordinator with a team. 

He was the Los Angeles Rams’ assistant special teams coach during the 2021 campaign that resulted in a Super Bowl win over the Cincinnati Bengals.

Stukes took the Broncos’ promotion before this season began, but he’ll now be looking for a new team to join. 

Like Stukes, Barry also took a promotion with the Broncos this season after serving as the assistant offensive line coach for the San Francisco 49ers last season. 

Barry was the University of Miami’s offensive line coach during the 2019 season, while also serving as a senior analyst with the Green Bay Packers during the 2020 campaign. 

DENVER BRONCOS FIRE HEAD COACH NATHANIEL HACKETT AMID 4-11 RECORD

It’s an interesting move by the Broncos to go through with these moves, as there’s still two games remaining on the schedule. But, with Hackett now gone and Jerry Rosburg taking over as interim head coach, Denver clearly doesn’t mind making some changes now. 

Offensive coordinator Justin Outten and defensive coordinator Ejiro Evero, who reportedly declined the interim head coach position, remain in the building for now. 

The small house cleaning by the Broncos comes on the heels of a 51-14 blowout loss to the Rams on Christmas Day, a game in which Russell Wilson threw three interceptions and Los Angeles scored on every offensive drive they put together. 

The Broncos are now 4-11 on the season and already eliminated from playoff contention. And to make matters worse, they won’t even be picking high in the first round of this year’s draft, as they spent a load of draft capital and more to land Wilson this past offseason.

They also signed him to a massive five-year extension worth $245 million, with $165 million guaranteed. 

In a statement, Broncos owner and CEO Greg Penner said, "Following extensive conversations with George [Paton] and our ownership group, we determined a new direction would ultimately be in the best interest of the Broncos."

"This change was made now out of respect for everyone involved and allows us to immediately begin the search for a new head coach. We recognize and appreciate this organization's championship history, and we understand we have not met that standard. Our fans deserve much better, and I can't say enough about their loyalty during such a challenging stretch for our team."
