It tv remote control is one of the unavoidable devices in the home, as it allows you to get started equipment system and take advantage of the various functions that the equipment may have.
Today, official and generic brands have evolved endless models and designs for these useful components, although in the past it was much more difficult to have them, to the point that they were considered precious things.
The history of this team spans over 70 years, roughly, when the television had complications from having to turn on manually. Therefore, the experts of time created first remote controlwhich has evolved into what today allows us just talk to access our favorite shows and movies.

light control
In the 1950s, the United States was one of the most advanced countries in terms of product technology, which made this device possible, which at first could only be used via light sensors.
While this method sounded groundbreaking for those years, in reality many users ended up complaining about the poor signal it sometimes showed. Nonetheless, it was a blast for the time and consolidated the company Zenith Electronics as a pioneer in this line, along with the company Flashmatic, which provided the technology for these devices.
Basically, the remote allows you to mute the sound, change the channel up or down, with just a blink of a button in the corner of the screen.

Space Command and first button control
Furthermore, Zenith doesn’t ignore claims for the first control it developed and removed light rays to design a system where you can ‘talk’ to the television. At first, the idea of using radio waves was discarded, so, in order to get rid of the method of aiming at a certain part of the screen, they proposed to put a button first.
This is how the so-called Space Command was born, working as an ultrasonic device using tiny hammers that internally hit an aluminum bar that controls volume and channel changes, as well as another new part: the menu.

numerical control
Already in the 70’s, the buttons were limited enough to expand the user experience, so in 1974 Ceefax, a British company dedicated to analog TV frequency service in the UK, wanted to revolutionize the choice of traditional remotes. .
This is how the company, taking into account that other audiovisual formats are now playable, set the options for rewind, pause, forward, but, without a doubt, the most important thing is the addition of numbers, which gives free will to decide which channel to tune without having to go through several .

Infrared light and the latest technology
Talking about the last years, but not so much, the company sees that video game controls are advancing at a higher rate than those dedicated to television production. For this reason, they added infrared light, which allowed the controls to no longer produce so much noise over time.
Between the 80s and 90s, the classic remote control we know today was given, which was only modified with new technology and more efficient buttons to be able to use it on streaming platforms, games, web pages, etc.
On the other hand, virtual assistants on today’s devices also fulfill the role of remote control, like mobile phones, although the former are more direct and multifunctional, because they will do what the owner tells them to do in real time.

What are the USB ports on the back of routers for and how can you take advantage of them?
charge other devices
One of the most common, and perhaps obvious, uses that a router’s USB port can provide is to charge another device, such as a cell phone, tablet or other device that has the same input. It should be noted that this connection does not guarantee that it will work in the same way as with a normal charger, but it is a great alternative in case of an emergency.
Automate backup
On the other hand, having a more complex system can increase the security of your data, as additional backup copies can be created automatically if a USB device or hard drive is connected to the router. It will only be enough to install the software so this part of the security is created from time to time.
Create a server with a USB stick or hard drive
Likewise, it is possible to create direct access to content belonging to other devices, which will practically serve as a new server for storing virtual elements. In other words, you can save and find files like any other computer memory, to view multimedia content such as photos and videos from other devices connected to the WiFi network.
