Timeline of United States inventions (before 1890)
Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
A timeline of United States inventions (before 1890) encompasses the ingenuity and innovative advancements of the United States within a historical context, dating from the Colonial Period to the Gilded Age, which have been achieved by inventors who are either native-born or naturalized citizens of the United States. Copyright protection secures a person's right to his or her first-to-invent claim of the original invention in question, highlighted in Article I, Section 8, Clause 8 of the United States Constitution, which gives the following enumerated power to the United States Congress:
In 1641, the first patent in North America was issued to Samuel Winslow by the General Court of Massachusetts for a new method of making salt. On April 10, 1790, President George Washington signed the Patent Act of 1790 (1 Stat. 109) into law proclaiming that patents were to be authorized for any useful art, manufacture, engine, machine, or device, or any improvement therein not before known or used. On July 31, 1790, Samuel Hopkins of Pittsford, Vermont became the first person in the United States to file and to be granted a patent for an improved method of Making Pot and Pearl Ashes. The Patent Act of 1836 (Ch. 357, 5 Stat. 117) further clarified United States patent law to the extent of establishing a patent office where patent applications are filed, processed, and granted, contingent upon the language and scope of the claimant's invention, for a patent term of 14 years with an extension of up to an additional 7 years. However, the Uruguay Round Agreements Act of 1994 (URAA) changed the patent term in the United States to a total of 20 years, effective for patent applications filed on or after June 8, 1995, thus bringing United States patent law further into conformity with international patent law. The modern-day provisions of the law applied to inventions are laid out in Title 35 of the United States Code (Ch. 950, sec. 1, 66 Stat. 792).
From 1836 to 2011, the United States Patent and Trademark Office (USPTO) has granted a total of 7,861,317 patents relating to several well-known inventions appearing throughout the timeline below.
Calling All Cars: Muerta en Buenaventura / The Greasy Trail / Turtle-Necked Murder
The radio show Calling All Cars hired LAPD radio dispacher Jesse Rosenquist to be the voice of the dispatcher. Rosenquist was already famous because home radios could tune into early police radio frequencies. As the first police radio dispatcher presented to the public ear, his was the voice that actors went to when called upon for a radio dispatcher role.
The iconic television series Dragnet, with LAPD Detective Joe Friday as the primary character, was the first major media representation of the department. Real LAPD operations inspired Jack Webb to create the series and close cooperation with department officers let him make it as realistic as possible, including authentic police equipment and sound recording on-site at the police station.
Due to Dragnet's popularity, LAPD Chief Parker became, after J. Edgar Hoover, the most well known and respected law enforcement official in the nation. In the 1960s, when the LAPD under Chief Thomas Reddin expanded its community relations division and began efforts to reach out to the African-American community, Dragnet followed suit with more emphasis on internal affairs and community policing than solving crimes, the show's previous mainstay.
Several prominent representations of the LAPD and its officers in television and film include Adam-12, Blue Streak, Blue Thunder, Boomtown, The Closer, Colors, Crash, Columbo, Dark Blue, Die Hard, End of Watch, Heat, Hollywood Homicide, Hunter, Internal Affairs, Jackie Brown, L.A. Confidential, Lakeview Terrace, Law & Order: Los Angeles, Life, Numb3rs, The Shield, Southland, Speed, Street Kings, SWAT, Training Day and the Lethal Weapon, Rush Hour and Terminator film series. The LAPD is also featured in the video games Midnight Club II, Midnight Club: Los Angeles, L.A. Noire and Call of Juarez: The Cartel.
The LAPD has also been the subject of numerous novels. Elizabeth Linington used the department as her backdrop in three different series written under three different names, perhaps the most popular being those novel featuring Det. Lt. Luis Mendoza, who was introduced in the Edgar-nominated Case Pending. Joseph Wambaugh, the son of a Pittsburgh policeman, spent fourteen years in the department, using his background to write novels with authentic fictional depictions of life in the LAPD. Wambaugh also created the Emmy-winning TV anthology series Police Story. Wambaugh was also a major influence on James Ellroy, who wrote several novels about the Department set during the 1940s and 1950s, the most famous of which are probably The Black Dahlia, fictionalizing the LAPD's most famous cold case, and L.A. Confidential, which was made into a film of the same name. Both the novel and the film chronicled mass-murder and corruption inside and outside the force during the Parker era. Critic Roger Ebert indicates that the film's characters (from the 1950s) represent the choices ahead for the LAPD: assisting Hollywood limelight, aggressive policing with relaxed ethics, and a straight arrow approach.
