Cartoons have existed on broadcast television for about seven decades. When they first came out, they aired on weekday afternoons and Saturday mornings. Many of the cartoon characters that people are most familiar with are Bugs Bunny, Mickey Mouse, Daffy Duck, Woody Woodpecker, Felix the Cat, Tom and Jerry, Popeye, and Screwy Squirrel. These were not actually created for television, but were initially displayed in theaters. Cartoons initially developed in the teens, but their development was slowed by their unaffordable cost. Teenagers weren’t interested in the cartoons so it became more expensive to air them on television if they didn’t have an audience watching them. Steamboat Willie, in 1928, was the first significant cartoon. Cartoons had been created by small studios with limited access to theaters. But in the 1930s, major studios such as Paramount, Warner Bros., Universal, and MGM signed deals with the cartoon studios. The Late 1930s to 1950s were a “golden era” for the cartoons. Cartoons started their emigration to television in the late 1940s when Van Beuren started to market their catalogue to early children’s programs. One of these included Movies for Small Fry. The early 1960s was when cartoons first became an established television feature. At this time there were two major controversies: commercialization/merchandising and violence. The issue of violence in cartoons and its impact on behavior has yet to be resolved.
People have different views about cartoons and the violence within them. Some researchers believe that high level of violence in cartoons can make children more aggressive. Their studies also found that young children tend to mimic the negative behavior they see on television. Output aimed at children as young as seven, which include a number of cartoons, had the highest levels of violence.
Some researches on the other hand believe that people need to consider the ways in which children process information, the amount of mental effort they invest, and their own life experience to gain an understanding of how television violence affects children. For instance recent research has indicated that children do not appear to mimic acts of violence in the media, whether television or cartoons. Blumberg, Bierwirth and Schwartz argue that children possess the ability to differentiate real life from animation, as well as the ability to understand right from wrong. They know that violent acts qualify as immoral and infringe on the welfare of others, therefore the violence witnessed in cartoons will register as "make believe" to children and will not be applied into their real lives. 
Options for Parents and Restriction
There are a number of ways parents can control their children’s exposure to violence. One of the most effective and common ways of prevention is restricting the amount and types of programs children watch. With older children, parents might want to discuss, and explain television. This can help children to understand television material and overcome the effect TV violence has on their outlook and behaviors.
Three initiatives have been put in place to combat violence in cartoons (). The first is The Children's Television Act which requires broadcasters to air shows which are educational and provide information for the children. The second initiative is the V-chip legislation that gives parents the opportunity to block out violent shows from their television. The third legislation against violent cartoons is the National Cable Television Association’s TV Parental Guidelines, which is a system that rates the Television shows based on their contents
In action-adventure oriented cartoons, the most consistent avenue of addressing violence is the use of a form of fantasy violence in which no one is injured or killed onscreen. In science fiction cartoons, for example, enemy forces are typically said to be robots so that they may be destroyed in bulk by the heroes without concern over killing living beings. In cases where vehicles are known to be piloted by living beings, tanks, aircraft, and other war vehicles that are destroyed in combat always allow time for the pilot to escape or bail out. Realistic firearms are often replaced with futuristic beam weapons which still seldom hit anyone. Swords and other bladed weapons may be prohibited from being used as offensive weapons but may be used defensively or be depicted as magical weapons. Direct violence is frequently limited to hand to hand combat where directly kicking or punching another character may or may not be allowed. The majority of action adventure cartoons over the past decades have used these methods of depicting dynamic action scenes although their use has been heavily criticized as "sanitized violence". Cartoons based on the Voltron, Transformers, G.I. Joe, and Masters of the Universe franchises (especially the versions produced during the 1980s) are notable examples using variations on fantasy violence.
Additionally, parents should limit the total screen time for children older than two years of age to no more than one to two hours per day. Children under two years of age should avoid watching television altogether. Televisions should be kept out of children’s bedrooms and parents should watch television with their children and discuss the content.
Health practitioners can also play their part by taking the time to ask their young patients how much time per day they spend with entertainment media and if there is a television or computer with Internet access in their bedroom. 
Effects of cartoon violence on youth remain controversial. Research has generally been divided on this issue  with no consensus reached regarding the effects of violence on behavior. That being said, the impact of exposure to violence may remain regardless of whether children choose to imitate it.
