What parents can do to limit watching television
Psychological studies have been repeatedly emphasizing on the influence of parents on the child’s developing values. It is, therefore, very important for adults to modify their recreational habits to best suit the needs of their children.
Balance television and video watching with other activities by planning a routine such as the following:
Ensure to keep the television off during meal times
Interact more often with your kids
Read out fables and stories to your children so that they spend minimum time in front of the television
Never use television as a reward or punishment or your children can misuse or manipulate you on those grounds.
Encourage and accompany your children and family to outdoor sport activities
Never use television as an alternative solution to rely upon when there is nothing else to do
Ensure that the television is placed at a common sitting room and neither in your children’s or your bedroom
Encourage entertaining and educational shows
Limit late night television
Television offers lots of benefits too as it brings a family together by shared views and thoughts. Moreover, it also offers a wide variety of cultural experiences to us. However, too much of anything is harmful for the mind and the body.
Steal the benefits of educational shows and entertainment keeping in mind that you do not over strain yourself. Never make television the only or the last option to do anything.
Since, television is usually watched more by children than the adults, it is important to break the habit. As television viewing affects children more than adults. Fit and healthy lifestyle should be the first priority for you and your children. Encourage your children to do more physical activity to stay away from obesity. One must discourage unhealthy eating habits. As far as possible, don’t feed your children colas and fast foods frequently. Children usually follow their adults. So, it is very important to inculcate these healthy habits in yourself. This will help not only in maintaining your child’s health but also your health. Too much television viewing can harm you too. So shut the television and pick up a good book instead. You can develop a hobby too. Or indulge in some kind of community and productive work during your leisure hours. This will surely improve your personality and character.

What are the effects of television on health
Obesity in children has also been linked with the amount of time spent on watching television. Diabetes also results from constant exposure to advertisements which promote the intake of sugar and fatty food. Artificial light or radiation being emitted from the television screens can lead to poor eyesight problems in children and adults alike. Sleeplessness can also result from watching too much of television. Difficulties in language acquisition and reading during the initial growth years of a child. Thinking and creative instincts are blocked. Continuous fatigue and headaches are the most possible outcomes of watching too much of television. Vomiting follows straight after a severe headache. The constant flickering and bright light can make the nervous system vulnerable in children. Children store negative thoughts about diet and dental care through advertisements and regular television watching.

Too much TV may mean earlier deathWatching too much television can make you feel a bit brain-dead. According to a new study, it might also take years off your life.
The more time you spend watching TV, the greater your risk of dying at an earlier age -- especially from heart disease, researchers found.
The study followed 8,800 adults with no history of heart disease for more than six years. Compared to those who watched less than two hours of TV per day, people who watched four hours or more were 80 percent more likely to die from heart disease and 46 percent more likely to die from any cause. All told, 284 people died during the study.

Television HistoryTelevision was not invented by a single inventor, instead many people working together and alone over the years, contributed to the evolution of television.
At the dawn of television history there were two distinct paths of technology experimented with by researchers.
Early inventors attempted to either build a mechanical television system based on the technology of Paul Nipkow's rotating disks; or they attempted to build an electronic television system using a cathode ray tube developed independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing.
Electronic television systems worked better and eventual replaced mechanical systems.

Science of sleep Health Care Summit is television's version of anesthesia

Science of sleep: Health Care Summit is television's version of anesthesiaMar 05 2010, New York — Since everyone else seems to have a suggestion on how to cut health care costs, here's mine: Pipe full-length DVDs of Thursday's Health Care Summit into every operating room in America and we will eliminate the need for any other form of anesthesia.
That should save a bundle.
You really wanted this seven-hour drama to become engaging, since it dealt with reasonably important matters like life, death and a few trillion of our dollars.
Trouble is, a TV show can't grab you if it can't keep you awake and the human body can take only so many exposures to phrases like "We use a high-risk pool until we get to the exchange" or "We aren't incentivizing prevention" before it falls asleep.
Now no one went into Thursday's Health Summit expecting "Jersey Shore South," with Nancy Pelosi as Snooki.
But after a year of posturing, speeches, sound bites and jargon from some other galaxy, I had this crazy hope that maybe the major players could sit down and agree in simple sentences what we should or shouldn't do next.

Rabbit Ears - AntennaeMarvin Middlemark invented "rabbit ears", the "V" shaped TV antennae. Among Middlemark's other inventions were a water-powered potato peeler and rejuvenating tennis ball machine.
Color TV was by no means a new idea, a German patent in 1904 contained the earliest proposal, while in 1925 Zworykin filed a patent disclosure for an all-electronic color television system. A successful color television system began commercial broadcasting, first authorized by the FCC on December 17, 1953 based on a system invented by RCA.
Cable television, formerly known as Community Antenna Television or CATV, was born in the mountains of Pennsylvania in the late 1940's. The first successful color television system began commercial broadcasting on December 17, 1953 based on a system designed by RCA.
It was in June of 1956, that the TV remote controller first entered the American home. The first TV remote control called "Lazy Bones," was developed in 1950 by Zenith Electronics Corporation (then known as Zenith Radio Corporation).
The American Broadcasting Company first aired Saturday morning TV shows for children on August 19, 1950.
The very first prototype for a plasma display monitor was invented in 1964 by Donald Bitzer, Gene Slottow, and Robert Willson.
TV closed captions are captions that are hidden in the television video signal, invisible without a special decoder.
Web TV was rolled out in 1996.

Paul Gottlieb Nipkow - Mechanical Television History

Paul Gottlieb Nipkow - Mechanical Television HistoryGerman, Paul Nipkow developed a rotating-disc technology to transmit pictures over wire in 1884 called the Nipkow disk. Paul Nipkow was the first person to discover television's scanning principle, in which the light intensities of small portions of an image are successively analyzed and transmitted.
In the 1920's, John Logie Baird patented the idea of using arrays of transparent rods to transmit images for television. Baird's 30 line images were the first demonstrations of television by reflected light rather than back-lit silhouettes. John Logie Baird based his technology on Paul Nipkow's scanning disc idea and later developments in electronics.


Charles Jenkins invented a mechanical television system called radiovision and claimed to have transmitted the earliest moving silhouette images on June 14, 1923.

Electronic television is based on the development of the cathode ray tube, which is the picture tube found in modern TV sets. German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT) in 1897.
Russian inventor, Vladimir Zworykin invented an improved cathode-ray tube called the kinescope in 1929. The kinescope tube was sorely needed for television. Zworykin was one of the first to demonstrate a television system with all the features of modern picture tubes.

In 1927, Philo Farnsworth was the first inventor to transmit a television image comprised of 60 horizontal lines. The image transmitted was a dollar sign. Farnsworth developed the dissector tube, the basis of all current electronic televisions. He filed for his first television patent in 1927 (#1,773,980).
Louis Parker invented the modern changeable television receiver. The patent was issued to Louis Parker in 1948.

Health Effects of Television
Spending hours before the television screen can have adverse effects on the health of a person. Experts believe that television has not only revolutionized communication but also the lifestyle habits of human beings.
There is a growing concern among parents for their children because they tend to spend much of their leisure time watching television. Therefore, media or television has creeped into our lives in such a way that we are almost living inactive lives today. This time can be allocated towards productive activities that are helpful for the overall fitness of the body.
Most homes today, boast of plasma screens where you can find the young and the old stuck to their television screens. Extensive studies have proved that television addicts can suffer from various health complications. Discover ways to check and prevent the frequent watching of television in the following article.

Health Effects of Excessive TV

Health Effects of Excessive TV
Watching by Childern
LimiTV recommends little-to-no TV viewing for children four-and-under and less than 10 hours per week (about 1 ½ hours per day) for children in grades K-12. These recommendations parallel similar guidelines of the American Academy of Pediatrics (AAP).
The following list some of the adverse effects on a child's health from spending too much time with TV and videos.
Overweight and DiabetesThe number of children and adolescents who are overweight or obese has doubled in the past 20 years in the U.S., according to the AAP. Even children younger than five, across all ethnic groups, have shown significant increases in overweight and obesity.
A number of studies have linked being overweight with TV watching, because it both reduces children's physical activity and subjects them to ads promoting foods with high fat and sugar content.
A television in a child's bedroom has also been reported as a strong predictor of overweight, even in preschool-aged children.
Risk Factors with OverweightAbout 85% of the children who develop diabetes are overweight, according to the AAP, making excess weight a strong risk factor for this chronic illness.
Other medical problems found in overweight children include high blood pressure, heart problems, high cholesterol, and depression and low self-esteem.
In addition to the health problems faced by overweight children, researchers find that the probability of childhood obesity persisting into adulthood increases from about 20% at four years of age to approximately 80% by adolescence. That means there is an 80% chance that obese teenagers will grow into obese adults and face all the serious health effects and life-span risks associated with that condition.
For these reasons, LimiTV strongly recommends minimal TV for preschoolers, a maximum of 1 ½ hours per day for school-age children, a healthful diet, and at least 30 minutes of physical activity each day.
Attention Deficit Disorder (ADD), Attention Deficit Hyperactive Disorder (ADHD)In the 1970s, the late researcher Professor Werner Halperin suggested that the rapid changes of sounds and images on TV may overwhelm the neurological system of a young child and cause attention problems that shows up at a later date.
Around the same period, Dr. Mathew Dumont of the Harvard Medical School suggested that the rapid changes of TV sounds and images may stimulate a child to mimic that dynamic behavior. That is, what we call ADHD may simply result from the child subconsciously copying the frenetic pace of TV programs. We now have a study that brings us solid findings about ADHD.
In April 2004, Dr. Dimitri Christakis and colleagues reported in the journal Pediatrics that early TV viewing (ages 1 and 3 were studied) is associated with attentional problems (ADHD) at a later age (age 7). The children studied watched a mean of 2.2 hours per day at age 1 and 3.6 hours per day at age 3.
Specifically, Christakis reports that watching about five hours of TV per day at age 1 is associated with a 28% increase in the likelihood of having attentional problems at age 7. A similar 28% increase at age 7 shows up for 3-year olds who watch about five hours of TV per day. Alternatively, each additional hour of TV watched above the mean at ages 1 and 3 increases the likelihood of attentional problems at age 7 by about 10%.
The authors include the following cautionary notes: (1) the determination of attentional problems (ADHD) was based on established checklists of behavior, not on a clinical diagnosis; (2) the authors relied on reports by parents to determine the amount of TV viewed - no direct monitoring of daily TV watching was done; and (3), the researchers had no data on the content of the TV programs watched.
Christakis and colleagues recommend that additional research be undertaken, and LimiTV strongly supports that. We also know, however, that each parent must make decisions based on what is currently known.
The steep rise in the number of children with ADD/ADHD, and the accompanying increase in the use of medications to treat these children (e.g., Ritalin), suggest that the problem is real and is being caused by something which is an inherent part of everyday life for American children.
Current findings suggest that TV watching in the early years may contribute to this behavioral problem. Therefore, LimiTV recommends minimal TV and video watching during the preschool years.
Doctors sometimes refer to the enormous brain development that occurs in the first few years of life as a 'wiring' of the brain, i.e., making connections between the billions of neurons with which we are born. TV watching in these crucial early years may affect this wiring. That is, if the hours of TV watched exceed a certain level, a child's brain may be wired to respond more to the TV environment (rapid changes of sounds and images) than the natural environment. That level has not yet been determined, but since the AAP recommends no TV watching for the first two years of life, we could assume the level is quite low. It is for this reason as well that LimiTV recommends little-to-no TV through age 4.
Emotional HealthJames Steyer, in The Other Parent (see Resources), reports that TV ads for children are often structured to make the child feel like a 'loser' or 'dork' if he/she does not get the advertised product. Young children are emotionally vulnerable and ads are developed to take advantage of that vulnerability.
This deplorable practice of preying on a child's self-esteem was criticized in an article in July 2000 titled, 'Stuffing Our Kids: Should Psychologists Help Advertisers Manipulate Children?' Allen Kanner of the Wright Institute and Tim Kasser of Knox College, the authors, reported that advertisers have hired psychological consultants to study every phase and stage of a child's life, and then used the results to develop sophisticated commercials that have the desired effect on our children.
The authors also wrote that a letter endorsed by 60 psychologists and mental health professionals was sent to the American Psychological Association requesting that they publicly denounce the use of psychological techniques to assist corporate advertising to children.
The average child watches over 40,000 commercials per year. In addition to potentially damaging a child's self-esteem, many ads also likely contribute to health problems, given that the most common products marketed to children include sugared cereals, candies, sodas, and snack foods. A child's diet heavy in such foods may contribute to the increase in the number of overweight children and the rise in diabetes, especially given the sedentary behavior of many children.
