Trend Number One: I would say that so called Reality Television is a major Trend with Americans these days. I believe that Reality TV is a Trend because it has seemed to stay around for well over a decade now and has seemed to stay a top watched and voted television category. Sure the types of reality shows have changed over time as people's interested have changed and grown but the concept itself has made and continues to make a mark on many Americans' lives.
Fad Number One: Like I said at the start of this post, I don't watch much TV but out of the couple shows that I do tend to catch myself watching and being attached to, several of them fit into the so called Reality Show category. A couple of my most favorite shows would have to be Dual Survival which airs on the Discovery Channel and Special Ops Mission which aired on the Military Channel. I consider these Fads because like all other Reality Shows, these two will also wash by the way side eventually to make room on the TV screens and in the hearts of Americans.

Fad Number Two: FACEBOOK!!!!! While Facebook seems to be a long lasting trend, looking back at a majority of other Social Networking websites it too will probably eventually loose its popularity to some extent. Whether Facebook meets the fate of some other Social Networking websites in the past and completely dies off or just becomes slightly less popular likes some others, only time will tell.
Trend Number Three: Country Music. Country Music has been a major category in music for a couple of decades now and continues to grow by fans, awards and music artists. Country music has been on several charts in recent years as being in the top 3 genres of music to be listened to on commercial radio. Fox Business did a Radio/TV story in November of 2011 about the growing popularity of Country music in the U.S. A video of the broadcast is attached to the following web link.

Fad Number Three: Popular Music Artists. Like many other things and people who are popular at any given time, music artists also tend to fade out in popularity over time. If you look back 15 years ago at the year 1997, according to the Billboard Music Awards,Country Music singer LeAnn Rimes was "Artist of the year." In 2011, Hip Hop artist Eminem was voted as "Artist of the year" for the Billboard Music Awards.
Trend Number Four: Popular Personal Fashion. Personal fashion has been a popular and competitive trend for many decades. Dating back to the mobster days of John Dillinger and the famed Zoot Suit and Top Hat to the appropriately name "Shock and Awe" wild and crazy clothing style of the 21st century which celebs such as Lady Gaga and Nicki Minaj have made popular to the youth population, fashion has remained a large part of society and popular culture over time.
Fad Number Four: Types of Popular Clothing Styles: During 1930s and into the early 1940s prior to the U.S. involvement in World War II, the American music Jazz Age in Harlem, New York made the Zoot Suit a very popular clothing item which quickly spread across the country to the personal interests of American men. In the 1990s and early 2000s baggy "gangster" pants were the top hit to teenage males across the country and in the late 2000s Slim-fit pants aka "Skinny Jeans" took over in the fashion scene with the current teenage population. I am attaching a link produced by smithsonian.org which includes a great article on the popularity of the Zoot Suit and important events which occurred in history in which the Zoot Suit had a large part in.

Trend Number Five: Slang Language Terms. The use of Slang expressions in language has probably been used in one fashion or another since the creation of human languages thousands of years ago. From the ancient Egyptians use of of simple yet detailed drawings in their hieroglyphics to the large use of slang words in American language today such as the terms Laugh Out Loud (LOL) and Best Friends Forever (BFF), slang in language has played a big part in all of our lives at one time or another.
Fad Number Five: Types of Popular Slang in Language: Although individual slang has remained a popular form of spoken language over time, the types of Slang words and terms used have changed and evolved with current trends. From the 1930s and using terms such as "Bean Shooter" "Gat" and "Convincer" commonly used by mobsters and gangsters to describe a gun, to the now widely used "Izzle" phase made popular by Rap artist Snoop Dogg, types of Slang in American language has changed over time and will continue to evolve to what is current and popular in the future.
