History
Television was not invented by a single person, but by several
individuals. The origins of what would become today's television
system can be traced back to the discovery of the photoconductivity
of the element selenium by Willoughby Smith in 1873 followed by the
work on the telectroscope and the invention of the scanning disk by
Paul Nipkow in 1884. All practical television systems use the
fundamental idea of scanning an image to produce a time series
signal representation. That representation is then transmitted to a
device to reverse the scanning process. The final device, the
television (or TV set), relies on the human eye to integrate the
result into a coherent image.
Electromechanical techniques were developed from the 1900s into
the 1920s, progressing from the transmission of still photographs,
to live still duotone images, to moving duotone or silhouette
images, with each step increasing the sensitivity and speed of the
scanning photoelectric cell. John Logie Baird gave the world's
first public demonstration of a working television system that
transmitted live moving images with tone graduation (grayscale) on
January 26th, 1926 at his laboratory in London, and built a
complete experimental broadcast system around his technology. Baird
further demonstrated the world's first color television
transmission on July 3rd, 1928. Other prominent developers of
mechanical television included Charles Francis Jenkins, who
demonstrated a primitive television system in 1923, Frank Conrad
who demonstrated a movie-film-to-television converter at
Westinghouse in 1928, and Frank Gray and Herbert E. Ives at Bell
Labs who demonstrated wired long-distance television in 1927 and
two-way television in 1930.
Color television systems were invented and patented even before
black-and-white television was working. Completely electronic
television systems relied on the inventions of Philo Taylor
Farnsworth, Vladimir Zworykin and others to produce a system
suitable for mass distribution of television programming.
Farnsworth gave the world's first public demonstration of an
all-electronic television system at the Franklin Institute in
Philadelphia on August 25th, 1934. All modern television systems
derive directly from Farnsworth's model.
The first regular television broadcast began in Germany in 1935,
using first an electronic system with 180 lines, followed in 1937
with an improved system with 441 lines. The first regular
television broadcasts with a modern level of definition (240 or
more lines) were made in England in 1936, soon upgraded to the
so-called "System A" with 405 lines. Regular network broadcasting
began in the United States in 1946, and television became common in
American homes by the middle 1950s. While North American
over-the-air broadcasting was originally free of direct marginal
cost to the consumer and broadcasters were compensated primarily by
receipt of advertising revenue, increasingly United States
television consumers obtain their programming by subscription to
cable television systems or direct-to-home satellite transmissions.
In the United Kingdom, France, and most of the rest of Europe, on
the other hand, operators of television equipment must pay an
annual license fee, which is usually used to fund the appropriate
national public service broadcaster.

Find these words, some of my favorite television shows, in the
puzzle and answer for the formulas below. It will help if you print
this out to solve.
Smallville, The Office, Alias, Buffy, Enterprise, Twilight
Zone, The Simpsons, Family Guy, Futurama, Seinfeld, X-Files,
Northern Exposure, Chips, A-Team, King of the Hill, Family
Ties
A) Find the total number of unused letters (not including Question
D) and divide that number by 3. With that product, subtract 111.
B) Two of the shows above have MAIN characters that share
a middle initial. Using the formula A=1/Z=26, find the number that
corresponds with that initial and subtract 6. Use Hint 1 below for
help if needed.
C) The star of one of the shows above co-starred in a movie with
and married a daredevil. Take their ages when they married and add
them together. Take this sum and subtract 56.
D) The puzzle contains the name of a very popular show that is
not listed above in the "Find" list. It is located in one of the
two rows, either horizontal or vertical, that contain no other used
letters. This show is named after a popular location. What year was
this fictional location actually established. Take the third number
of this year and divide by 2. Use Hint 2 for help if needed.
E) There are 16 rows from top to bottom (horizontally) in the
puzzle above. Using the top row as 1 and the bottom as 16, what row
has the most used letters in it? Take that row number and add
7.
F) One of the shows above features a very popular "mayor" on a
regular basis. This "mayor" used to star in a very popular one-word
titled show. Find the year that that one-word titled show first
aired. Take the third number of that year and subtract 4. Use Hint
3 for help if needed.
