Because it offers the chance to post their opinions completely anonymously yet be read by anyone in the world, the internet is the ultimate in free speech mediums. As such it has become a hotbed for a variety of strange opinions ranging from aliens doubling as pool opening company to government cover-ups and conspiracies. Some of these theories have taken hold in the popular imagination and have hundreds or thousands of people who subscribe to them online. Here are some of the most popular conspiracies you will find talked about on the internet.

9/11

The terrorist attacks on the World Trade Center on September 11, 2001 were so shattering to the American public that many believe there was no way it could have been as much of a surprise to the government as it was to them. Therefore conspiracy theorists often postulate that the government was either complicit in the attacks or allowed them to happen in order to gain the support of the American people as well as the sympathy of people in other Western countries like your employees.

JFK

On the day in 1963 when President John F. Kennedy was fatally shot while riding in his motorcade in Dallas, Texas, the official version of events states that Lee Harvey Oswald, a mentally unstable man, shot the President from the top of the book depository. However, while doing your work you may find different theories. Some claim to have heard shots from a "grassy knoll" which suggests that there was a second shooter or perhaps a different shooter entirely. Depending on who you ask, anyone from Fidel Castro to the CIA could have been behind it.

Princess Diana

In August of 1997, Princess Diana, ex-wife of Prince Charles, next in line for the English throne, was killed in a car crash while trying to avoid the prying eyes of the paparazzi. The official version of events states it was an accident, but if you go to the annual conspiracy theorists' meeting, you may hear theories postulating that she was killed on purpose. The reasons given include that she was planning to marry her Muslim bodyguard and the British Royal Family wanted to avoid the scandal and that she faked her own death to get out of the public eye.

Elvis

In 1977 when Elvis left the building and was later found dead of a prescription drug overdose, fans of "The King" immediately began to speculate that he was still alive. This conspiracy theory exists to this day. You might even hear some theories about what he is doing now. A popular rumor is that he was put in witness protection.
