Applied films have made it possible for televisions to look vastly different than the hefty boxes filled with dials and vacuum tubes that once characterized the television landscape. Today we have TVs that are flat as boards and light enough for one person to manage along. There are massive screens that dominate whole walls and tiny ones that can fit into the seat back of a taxi. But it's not just the television itself that has changed. The programs we see on TV and the uses we make of our TVs have changed as well.
One of the biggest changes in the television landscape today is the changeover from standard analog broadcasts to digital, fiber optic, and high definition feeds. With high definition, the picture is so clear that often television shows have to change the way they are filmed in order to display properly. Big cities tend to have more high definition programming than smaller towns and countries.
Along with the digital television revolution comes the switch from recording television shows onto VHS tapes to recording them digitally onto a recorder that is contained within your cable box. The major advantage of DVR systems such as Tivo is that they are connected directly to the cable company's schedule, allowing you to simply select programs from the grid and set them to record then watch at your convenience. They also allow you to pause and rewind live television.
In addition to your DVR, you probably also have a lot of peripherals attached to your television. You'll have a DVD player, perhaps a Blu-Ray disc player for HD movies, a video game system such as the Wii or the Xbox One, and maybe even a surround sound system. It gets to the point where our homes are overrun with electronics, but it allows us to do almost anything on our televisions - watch movies, surf the internet, play video games, view slide shows, even listen to music!
It used to be that if you wanted to enjoy something in full 3D you had to look at it in person. Now, there are special televisions that have been adapted to show programs in the same 3D that is currently used in feature films at the theater. Though very few broadcast programs are shown in 3D, purchasing a 3DTV will allow you to view Blu-Ray copies of your favorite films the way they were meant to be shown. Currently 3DTVs require special glasses, but the day is coming when they'll be obsolete - as will 2D TV!
