what is the streaming?

transmission by streamingalso called streaming, streaming, or streaming, It is a method of distributing multimedia (audiovisual) content through computer networks, which transmits the content the moment it is consumed., without having to download and store it beforehand. The term streaming comes from English streaming (“jet” or “stream”) and refers to the uninterrupted transmission of audiovisual content.

The transmission of commercial content via streaming became popular after the year 2000 throughout the world, as broadband services made it possible to equalize the data transmission rate necessary to transmit series, movies, podcasts and other delayed content (that is, previously recorded) or different live and direct television services. Unlike traditional television or radio broadcasts, it had the virtue that the user can choose what content to see and when.

To have access to this type of services an internet connection and one or more devices capable of playing audio and video are requiredsuch as smart TVs, tablets, smartphones or computers. The success of this technology, therefore, goes hand in hand with the increase in the consumption of this type of device, and the improvement in the capacity for wireless data transmission (4G and 5G).

As it happens with other anglicisms, that is, other loans from English into Spanish, the word streaming It should always be written in italics.

In the following years, the giants of the entertainment industry appeared via streaming, both in the television and film area, as well as in video games, radio on-line and the podcasts.
