Communication has evolved significantly over time, from early symbolic forms like cave paintings to modern digital networks. Early developments included the use of drums and smoke signals, while later symbolic forms like pictograms and ideograms improved information transmission. Writing systems then emerged to record information permanently. The telegraph, telephone, radio, and television further advanced long-distance communication. The internet revolutionized global connectivity through protocols like TCP/IP and email standards. Communication continues to progress in line with humanity's changing information needs.

Trends in the Development of Communication
Communication has been one of the major tools driving the economies of the world.
Since time immemorial, rigorous developments have occurred in the communication industry
following the discovery of varied and refined communication devices. In essence,
communication refers to full conversations, mass communication and very delicate exchange
processes (Crowley and Paul 35). The evolution of communication, through human speech, took
place as early as 200,000 years ago, with the development of symbols taking place in the last
30,000 years. Such developments have been enhanced by the devolution of ideas from the human
brain passed on from generation to generation, which has long since been critical in the
development and mastery of speech, distinguishing human beings from other creatures. Speech
has thus been paramount in facilitating the transmission of knowledge and information to
successive generations.
In prehistoric times, people used to paint on cave walls as a way of communicating views
and recording information about their culture, society and events. The urge to send and relay
information to distant communities and tribes drove people to adopt drums to convey these
messages (Noll 12). To add to this list was the use of smoke to communicate to far community.
Following the development of speech, the situation changed for the better in that humans could
now transfer knowledge and experience from generation to generation, allowing them to adapt to

new environments or to influence the environment in their favor at a higher rate than before.
Following the development of speech, advancements in cooperation and coordination facilitated
the establishment of abstract and complex concepts, such as religion, and this development
enhanced human control over the entire planet (Katz). However, imperfections in speech, such as
those caused by distance, and the reliance on human memory, such as limitations in the extent of
information recalled or the death of a person with certain information became a challenge and
prompted the development of symbols.
Symbols were developed to make up for the limitation in speech and to facilitate easier
broadcast of information. Symbols thus improved both the long life at which information could
be passed on and the range of communication improved. According to Noll (15), symbolism
refers to as usual method of representing ideas. The most significant communication symbols of
time were Paleolithic cave paintings. Though not standardized, this method was much more
efficient for passing on information; this in linguistics is explained as the connection between
drawing and writing, as a way of passing on information through occurrences and events, this
were painted on the caves walls, though not very reliable because the paintings faded with time.
At around 10,000 BC, petroglyphs, or carving onto rock surfaces, became the next step in
communication (Crowley and Paul 34). Other means of communicating through symbols
involved the use of tattoos, ropes that were Quipu-like and the use of stone and wood to carve
symbols (Katz 17).
Pictograms were later invented as an even more efficient means of communicating
concepts through illustration. According to Noll (27), a pictogram refers to the idea of
representing an event, concept, activity or object through the use of illustration and thus is a type
of proto-writing. While petroglyphs generally represent an event, pictograms illustrate the story

behind the event and hence allow for the sequencing of events in chronological order (Noll 43).
Having been used by various cultures, pictograms came to be used in communication in about
9000 BC, with farm produce being marked with simple picture-marked tokens. Pictograms
became even more popular between 6000 and 5000 BC when they became the basis for
hieroglyphs and cuneiforms and were developed into logographic writing systems in around
5000 BC (Crowley and Paul 36). With the increased need for specialization and efficiency in
communication, ideograms developed to replace pictograms. Ideograms, such as the Indus or
Vinca script, were basically an evolution of earlier pictograms and are generally graphical
symbols representing an idea; hence, they were the basis for the logographic writing technology
which included systems such as Chinese characters and Egyptian hieroglyphs (Noll 59).
The ideographic and pictographic elements influenced the development of writing.
Writing systems are broadly grouped into three types: alphabetic, logographic and syllabic,
although all three can be in use in any writing but in varying sizes (Katz 35). The development of
writing was encouraged by the need for early communities to preserve records, contracts,
calendars and land deeds and the need for a storage means that would be permanent,
transportable, readily made and cheap to store, and fixed to avoid adjustments. The earliest
writing system was developed in the early Bronze Age. Resulting from clay tokens, writing
became more advanced around the end of the 4th millennium BC following the development of
the stylus (round shaped) system which was usually impressed at varying angles into soft clay
and used for recording numerals.
Later, pictographic writing was invented, and this inspired cuneiform (wedge-shaped
stylus the new writing which was adopted) which was employed to represent the Sumerian
spoken language (Noll 68). Around 500 BC, cuneiform had become a general purpose method of

writing for numbers, syllables and logograms in Hittite, Old Persian and Ugarithic, and this also
included Chinese script. Around 2000 BC, the first alphabet was developed in Egypt (Crowley
and Paul 79), the first pure alphabet used to represent single symbols which in return represent
single phonemes. By 2700 BC, Egyptian writing included a set of close to twenty-two
hieroglyphs representing syllables that began with a single consonant in the Egyptian language.
These were later used as guides in pronunciation.
The need to communicate more efficiently, more rapidly and to secure information from
loss or interruptions encouraged the need for the development of telecommunications. This
began in the 1770s with the introduction of the first semaphore system in Europe followed in the
1830s by the invention of electrical communication. In 1772, the world’s first telegraph service,
between Lille and Paris, was developed by Claude Chappe (Katz 67). Abraham Edelcrantz
developed a slightly different system that relied on shutters and was thus much faster, though his
telegraph faced the challenge of expensive towers and a lack of skilled operators.
Germany’s Samuel Thomas developed the electrochemical telegraph, utilizing multiple
wires to visually represent every Latin numeral and letter. Sir Charles Wheatstone and Sir David
Brewster built the earliest commercial electrical telegraph in the 1830s and, unlike the
electrochemical one; it could be used to communicate over long distances (Noll 89). The
development of the register enhanced the development of the first Atlantic telegraph system
cable. In 1876, Alexander Graham invented the first telephone, based on the idea of telegraph.
This was followed by the wireless telephone utilizing modulated light beams from photo phones
(Crowley and Paul 103).
Utilizing the principles of wireless telegraphy, Reginald Fessenden was able to transmit
the human voice in a wireless media, and this led to the invention of the radio. In 1925, John

Baird developed the system that could transmit moving pictures utilizing halftone shades. Using
Nipkow disks, Baird produced the first mechanical television, used in the British Broadcasting
Corporation’s experiments in 1929 (Katz 79). Karl Braun developed the cathode ray tube that
remained in use in televisions throughout the 20th century. Later, the development of television
networks and microwave radio relay saw huge improvements in audio-visual broadcasting
(Crowley 112). In 1940, George Stibitz pioneered the development of the mainframe computer
following his experimentation with teletype (Noll 102). The mainframe (centralized computer)
dominated in the 1950s, when researchers developed packet switching technology to allow data
communication without the need for a mainframe computer. The ARPANET later emerged in
1981 following extensive research and consisted of 213 nodes (Katz 123).
The ARPANET later merged with other similar networks, establishing the Internet,
whose numerous procedures are in use today and became specified in this merger process. The
Transmission Control Protocol (TCP), and the V4 Internet protocol were developed in 1981, and
much of the internet nowadays relies on this innovation (Noll 137). The SMTP email protocol
was developed in 1982 by Request for Comment (RFC) 821 while the protocol that
revolutionalized the ability for a hyperlinked internet was developed in 1996 by RFC 1945 (Noll
147). However, the 1970’s Local Area Network (LAN), 1976’s Ethernet and 1974’s Token Ring
protocol were developed separately from the RFC processes (Noll 149). Communication has
continued to evolve over time with the changing needs of the human race and the nature of
events. This has been because of the changing trends of human being and the growing demand
for new development in technology triggered by competition among major producers of
communication appliances.
