CBS to serve as a headquarters for A&M Records. A&M Records had grown from $500,000 in revenues in 1964 to $30 million in 1967. Alpert and Moss reportedly "astonished the big network by having their bank deliver a cashier's check for more than $1 million, the full amount." A&M converted two of the old soundstages and Chaplin's swimming pool into a recording studio. A 1968 profile on Alpert and Moss described their renovation of Chaplin's old studios: "The old sound stages are in the process of being completely rebuilt into what must be the most luxurious and pleasant recording studios in the world. Chaplin's cement footprints are one of the few reminders of the past. In February 1969, the studios were designated as a Los Angeles Historic-Cultural Monument. At the time, Carl Dentzel, the President of the Los Angeles Cultural Heritage Board, said the property was one of the few locations from old Hollywood that retained a complete early-day production layout. Dentzel also noted, Chaplin's "studio was one of the first to be established here and by some quirk of fate continuity from the movies' earliest times to today's television and recordings demands has persevered." The studio was only the second entertainment-related building to receive the Historic-Cultural Monument designation after Grauman's Chinese Theatre. The elderly Chaplin briefly revisited his former studio in April 1972, when he made his only return trip to America to accept an honorary Academy Award. A&M had hoped to welcome him back with a ceremony, but instead he chose to avoid the attention and arranged to drive by the studio gates on a weekend. In April 1989, the organization "Hollywood Heritage" celebrated the 100th anniversary of Chaplin's birth with a rare screening of Chaplin's 1918 documentary How to Make Movies and The Kid, both shown at the Chaplin Stage at A&M Records. Chaplin's son, Sydney, received a plaque at the screening honoring his father's achievements. For the 1992 biopic Chaplin, an exterior set of the studio office buildings was constructed among the orange groves north of Los Angeles at Fillmore, Route 126 between Ventura and Valencia. The actual studio is shown near the end of the film, where Chaplin's limousine is depicted stopping at the gates in 1972. The Jim Henson Company (2000–present) In February 2000, Jim Henson's children purchased the studio for $12.5 million to serve as the new home of The Jim Henson Company.
