Man has made infinite inventions in last 5 decades. Technology is updated every minute. The stuff which is new this moment, would become obsolete the next ! From the day Television invented, life has changed a lot. It was a revolutionary invention in those days.
There were only few tv channels in 60s but today there are around 500 ! So now guess a life without remote ! how does that sound ? If you had no remote, you had to get up from couch to change every single channel. That is really annoying. When remotes arrived first, they were not capable of jumping randomly to desired channel, one had to travel through sequence of channels.
Ok, stop imagining, I read an article about tv remote control, its origin and avatars. If you are interested to know how remote changed our life and why it could be considered as one of the important inventions by mankind, Check this article on Technologizer. It is worth knowing ! ;) It is really fun to read about this magical device which has transformed our lives(and many times by itself !!).
