Intermission features

Because live opera includes lengthy intermissions between multiple acts, the Metropolitan Opera radio broadcasts offer informative and entertaining opera-related intermission features. These include discussions of the opera being performed, roundtables, quizzes, interviews with various current and retired opera performers, and information on notable behind-the-scenes Met staff members. Since 2006, the lead singers of the day's opera have also been interviewed live as they leave the stage. Starting in December 2009, a new feature called ''Talking Opera'' explains various terminology used in the opera world. Among the most popular intermission features is the ''Opera Quiz''. The quiz is usually about 20 minutes long and features a host asking a panel of three experts questions about opera which have been submitted by listeners. First introduced on December 7, 1940 as the ''Opera Question Forum'', the Quiz was originally hosted by Milton Cross. Robert Lawrence was the Quiz host in the 1941/42 season. The 1942/43 broadcast season began with Robert Lawrence alternating with

Other intermission features over the years have included ''Opera News on the Air'', the ''Singers’ Roundtable'', and annual interviews with the Metropolitan Opera’s general managers. Boris Goldovsky, an opera producer and lecturer known for making opera more accessible to audiences, hosted a series of musical lectures from 1946 to the mid-1980s. Analyzing the opera being performed that day, he spoke and played the piano, illustrating his comments with musical excerpts.

Peabody Awards

The Metropolitan Opera radio broadcasts have won over 60 awards, including multiple

s, the highest honor in radio broadcasting. In 1950, the Metropolitan Opera, ABC Radio, and the Texas Company (

, the series' long-term sponsor) were awarded the Peabody Award in music for "public service in making the most brilliant opera company in the world a by-word in millions of homes." The announcement commended the "great artists," the "superlative orchestra," and the intermission features, as well as the series' spin-off programs such as the ''Auditions of the Air'' and the ''Opera Album''. In 1954, the Peabody committee gave a Personal Award for Radio Music to Boris Goldovsky, via the Metropolitan Opera radio broadcasts. The Peabody announcement noted Goldovsky's contagious enthusiasm for opera, evident in his decade of hosting intermission features and interviews on the Met broadcast series. In 1960, the Texaco-Metropolitan Opera Network was awarded a Peabody Institutional Award for Radio Public Service. The Peabody committee cited 20 years of public service "of inestimable cultural value," and mentioned the carefully planned intermission programs and high-level music commentary. The committee also noted the "long-time excellence of this series, the good taste and restraint in the commercial identification," and the international use of the broadcasts. In 1982, Texaco and the Metropolitan Opera were awarded a Peabody for excellence in both radio and television broadcasting. The Peabody committee cited the more than four decades of radio broadcasts, the continued technical refinements and improvements in sound, and the "informative intermission features, intelligent narration, and outstanding musical quality." In 1989, its 50th year of broadcasting, the Texaco-Metropolitan Opera radio series received another Peabody Award. The committee noted that "the Met Opera has been continually innovative in its presentation. Sound quality is excellent, performances are first-rate, and the entertaining intermissions have become outstanding programs in their own right."
