Question: What year was the studio space converted to a sports club?
About the article "Grand Central Terminal", section "Terminal City".

Candidate passages:
The Studio was the name of a small artists' loft commune formed in 1975 by four comic book artists/commercial illustrators/painters in Manhattan's Chelsea district.
These artists were Barry Windsor-Smith, Jeff Jones, Michael William Kaluta, and Bernie Wrightson — known colloquially as the "Fab Four".
The studio space was a converted machine shop with high ceilings.
Industry journalist Tom Spurgeon commented on the broader significance and influence of The Studio in his 2011 obituary of Jones at "The Comics Reporter": The legacy of that much talent doing what was collectively very good work at a point of almost monolithic and degrading corporate influence over the kind of art they wanted to do has provided The Studio with a legacy that can be embraced even by those that didn't particularly care for the artists' output.
The idea of a dedicated workplace that would allow for coercive influence one artist to another has been carried over into very nearly ever cartoonists' collective space initiative since.
By 1979, the "Fab Four" had produced enough material to issue an art book under the name "The Studio", which was published by Dragon's Dream.
That same year the members of The Studio moved on to independent projects and work spaces. 
 (2005-).
The complex was renamed "King's Meadow Campus" in 2005, and now houses a café where the Sports & Social Club was.
The original staff canteen and most of the floor-space in the studios has been converted to office and lecture space.
In 2007, the campus opened a fitness centre called "King's Meadow Campus Fitness Centre". 
The Studio provides a smaller performance space, seating 146 people which hosts small scale contemporary dance, theatre, jazz, blues, folk and comedy.
The space can be used in a flat-floor format so can be converted for film previews, club nights, cabaret seated events, workshops and rehearsals. 
The New England Sports Center has a large, carpeted, glass-wall exercise room located on the second floor between Rink 2 and Rink 5.
Previously used for seminars, semi-formal events, business meetings, and as a scouting area, the space was converted to a physical fitness area in 2013. 
When "Queen Mary" was bought by Long Beach, the new owners decided not to preserve her as an ocean liner.
It had been decided to clear almost every area of the ship below "C" deck (called "R" deck after 1950, in order to lessen passenger confusion, as the restaurants were located on "R" deck) to make way for Jacques Cousteau's new Living Sea Museum.
This would increase museum space to .
It required removal of all the boiler rooms, the forward engine room, both turbo generator rooms, the ship stabilisers and the water softening plant.
The ship's now empty fuel tanks were then filled with local mud which would keep the ship's centre of gravity and draft at the correct levels, as these critical factors had been affected by the removal of the various components and structure.
Only the aft engine room and "shaft alley", at the stern of the ship, would be spared.
Remaining space would be used for storage or office space.
One problem that arose during the conversion was a dispute between land-based and maritime unions over conversion jobs.
The United States Coast Guard had final say; "Queen Mary" was deemed a building, since most of her propellers had been removed and her machinery gutted.
The ship was also repainted with its red water level paint at a slightly higher level than previously.
During the conversion, the funnels were removed as it was the only practical way to lift out the scrap materials from the engine and boiler rooms.
It was subsequently found that the funnels were significantly degraded, and they were replaced with replicas.
With all of the lower decks nearly gutted from R deck and down, Diners Club, the initial lessee of the ship, was to convert the remainder of the vessel into a hotel.
Diners Club Queen Mary dissolved and vacated the ship in 1970 after their parent company, Diners Club International, was sold, and a change in corporate direction was mandated amidst the conversion process.
Specialty Restaurants, a Los Angeles-based company that focused on theme-based restaurants, took over as master lessee the following year.
During this conversion, the plan was to convert most of her first- and second-class cabins on A and B decks only into hotel rooms, and convert the main lounges and dining rooms into banquet spaces.
On Promenade Deck, the starboard promenade would be enclosed to feature an upscale restaurant and café named Lord Nelson's and Lady Hamilton's; it was themed in the fashion of early-19th-century sailing ships.
The famed and elegant Observation Bar was redecorated as a western-themed bar.
The smaller first-class public rooms, such as the Drawing Room, Library, Lecture Room and the Music studio, would be stripped of most of their fittings and converted to commercial use, heavily expanding the retail presence on the ship.
Two more shopping malls were built on the Sun Deck in separate spaces previously used for first-class cabins and engineers' quarters.
A post-war feature of the ship, the first-class cinema, was removed for kitchen space for the new Promenade Deck dining venues.
The first-class lounge and smoking room were reconfigured and converted into banquet space, while the second-class smoking room was subdivided into a wedding chapel and office space.
On the Sun Deck, the elegant Verandah Grill would be gutted and converted into a fast-food eatery, while a new upscale dining venue was created directly above it on Sports Deck, in space once used for crew quarters.
The second-class lounges were expanded to the sides of the ship and used for banqueting.
On R deck, the first-class dining room was reconfigured and subdivided into two banquet venues, the Royal Salon and the Windsor Room.
The second-class dining room was subdivided into kitchen storage and a crew mess hall, while the third-class dining room was initially used as storage and crew space.
Also on R deck, the first-class Turkish bath complex, the 1930s equivalent to a spa, was removed.
The second-class pool was removed and its space initially used for office space, while the first-class swimming pool was used for hotel guests.
Combined with modern safety codes and the structural soundness of the area directly below, the swimming pool is no longer in use.
No crew cabins remain intact aboard the ship today.
After the conversion, little of the original Queen Mary is still intact today, with most of the remaining closed off and used for banquet space.
