2. Multimedia is media and content that uses a combination of
different content forms. The term can be used as a noun (a
medium with multiple content forms) or as an adjective
describing a medium as having multiple content forms. The
term is used in contrast to media which use only
rudimentary computer display such as text-only, or
traditional forms of printed or hand-produced material.
Multimedia includes a combination of text, audio, still
images, animation, video, or interactivity content forms.

3. The printing press was invented in the Holy Roman Empire by
the German Johannes Gutenberg around 1440, based on
existing screw presses. Gutenberg, a goldsmith by profession,
developed a complete printing system, which perfected the
printing process through all of its stages by adapting existing
technologies to the printing purposes, as well as making
groundbreaking inventions of his own.

4. The newspaper in its modern
form is usually regarded as
beginning in 1566, when the
government of Venice, Italy,
issued written news-sheets
and exhibited them in the
streets. Anyone was allowed
to read them on payment of a
small coin called Gazetta. On
this account the news-sheets
were called gazettes.

5. In 1822, Charles Babbage proposed the use
of such a machine in a paper to the Royal
Astronomical Society on 14 June entitled
"Note on the application of machinery to the
computation of astronomical and
mathematical tables". This machine used the
decimal number system and was powered
by cranking a handle.

6. The Analytical Engine was a proposed
mechanical general-purpose
computer designed by English
mathematician Charles Babbage. It was first
described in 1837 as the successor to
Babbage's Difference Engine, a design for a
mechanical computer.

7. In 1879 Thomas Edison granted the
patent of photographs.

8. 1886:Burroughs First commercially
successful adding machine.

9. The first primitive radio transmitters (called
Hertzian oscillators) were built by German
physicist Heinrich Hertz in 1887 during his
pioneering investigations of radio waves.
These generated radio waves by a high
voltage spark between two conductors.

10. The tabulating machine was an electrical device designed
to assist in summarizing information and, later,
accounting. Invented by Herman Hollerith, the machine
was developed to help process data for the 1890 U.S.
Census. It spawned a larger class of devices known
as unit record equipment and the data processing
industry.

11. In 1890, Louis Glass and William S.
Arnold invented the nickel-in-the-slot
phonograph, the first of which was an
Edison Class M Electric Phonograph
retrofitted with a device patented
under the name of Coin Actuated
Attachment for Phonograph. The
music was heard via one of four
listening tubes. Early designs, upon
receiving a coin, unlocked the
mechanism, allowing the listener to
turn a crank which simultaneously
wound the spring motor and placed
the reproducer's stylus in the starting
groove.

12. Steamboat Willie is a 1928
American animated short
film directed by Walt
Disney and Ub Iwerks. It was
produced in black-and-white
by The Walt Disney Studio and
released by Celebrity
Productions. The cartoon is
considered the debut of Mickey
Mouse, and his
girlfriend Minnie.

13. Magnetic tape was invented for recording
sound by Fritz Pfleumer in 1928 in
Germany, based on the invention of
magnetic wire recording by Valdemar
Poulsen in 1928. Pfleumer's invention
used a ferric oxide (Fe2O3) powder
coating on a long strip of paper. This
invention was further developed by the
German electronics company AEG, which
manufactured the recording machines
and BASF

14. The Atanasoff–Berry Computer (ABC) was the
first electronic digital computing device. Conceived in
1937, the machine was not programmable, being
designed only to solve systems of linear equations.

15. 1943:Zuse – Z3: First machine to
work on a binary system rather than
decimal system.

16. 1948:Shockley, Bardeen and
Brattain develop the transistor.
More reliable and cheaper to run
the vacuum tube.

17. IBM 701: First electronic stored
computer that use vacuum tubes, Ram,
punch cards and was the size of a piano,
was announced to the public on April 29,
1952

18. In 1972 the first
commercial video
game was released
by he atari inc.

19. SONY Betamax
VCR with a one
hour, ½ inch video
cassette
tape.1975.

20. Facebook was launched in February 2004, owned and operated
by Facebook, Inc. Facebook was founded by Mark
Zuckerberg with his college roommates and fellow
students Eduardo Saverin, Andrew McCollum, Dustin
Moskovitzand Chris Hughes. The website's membership was
initially limited by the founders to Harvard students, but was
expanded to other colleges in the Boston area, the Ivy League,
and Stanford University.

21. YouTube is a video-sharing website,
created by three
former PayPal employees in February
2005, on which users can upload, view
and share videos.

22. Twitter is an online social networking service and micro
blogging service that enables its users to send and read text-based
messages of up to 140characters, known as "tweets". It was created in
March 2006 by Jack Dorsey and launched that July. The service
rapidly gained worldwide popularity, with over 500 million active
users as of 2012, generating over 340 million tweets daily and
handling over 1.6 billion search queries per day.
