Question: Extract the answer to the question from the following context. Question: What was common function of electric recordings? Context: Eventually, when it was more common for electric recordings to be played back electrically in the 1930s and 1940s, the overall tone was much like listening to a radio of the era. Magnetic pickups became more common and were better designed as time went on, making it possible to improve the damping of spurious resonances. Crystal pickups were also introduced as lower cost alternatives. The dynamic or moving coil microphone was introduced around 1930 and the velocity or ribbon microphone in 1932. Both of these high quality microphones became widespread in motion picture, radio, recording, and public address applications.

Question: Extract the answer to the question from the following context. Question: Apple's ad of 1984 denotes freedom from which company's monopolistic reign? Context: After the Lisa's announcement, John Dvorak discussed rumors of a mysterious "MacIntosh" project at Apple in February 1983. The company announced the Macintosh 128Kmanufactured at an Apple factory in Fremont, Californiain October 1983, followed by an 18-page brochure included with various magazines in December. The Macintosh was introduced by a US$1.5 million Ridley Scott television commercial, "1984". It most notably aired during the third quarter of Super Bowl XVIII on January 22, 1984, and is now considered a "watershed event" and a "masterpiece." Regis McKenna called the ad "more successful than the Mac itself." "1984" used an unnamed heroine to represent the coming of the Macintosh (indicated by a Picasso-style picture of the computer on her white tank top) as a means of saving humanity from the "conformity" of IBM's attempts to dominate the computer industry. The ad alludes to George Orwell's novel, Nineteen Eighty-Four, which described a dystopian future ruled by a televised "Big Brother."
Answer:
IBM
