Today most projectors are digital so you can easily watch movies, present slide shows, and conduct seminars easily with the device. It is quite simple to travel around the world giving presentations with only a laptop computer and a quality projector. There are plenty of different accessories you can use to make using a projector even easier. One of the most common ones is the wireless remote. This allows the speaker to move freely around the room and still be able to advance the projector to the next frame.
Projectors are used in many places all over the world to provide information. They are used in classrooms so teachers can show films or teach new concepts. Projectors are used by companies of all sizes and in all areas to teach employees valuable skills they can use to work smarter. As technology continues to improve there will be many more changes to the projector as time goes on.

A Brief History of Projectors
Film projectors have been in use since the mid 1600’s and they have improved significantly over time. The early film projectors involved reflecting sunlight from a mirror onto a lens. This allowed the images to be shown on a screen. At that time what we know call a projector was known as a magic lantern. It wasn’t until 1952 when projectors were able to work using electricity that they became popular for movie theatres and other types of businesses.
Advances with projectors have been relatively slow though throughout history. In the mid 1990’s the first multimedia projector was introduced. It was created by scientists and researchers employed by the company Texas Instruments. This particular device allowed a small microchip to hold all the reflecting power needed to produce images.
It was improved upon again in 1996 when the first wireless projector was introduced. It was called the Focus System with very precise images and the ability to show colors quite vividly. The sound quality was also enhanced with built in speakers. This particular type of projector was in such high demand that it wasn’t long before the market was saturated with various models offered by top manufacturers. This resulted in projectors becoming more affordable as well as more advanced.
