What is Streaming? Netflix and YouTube Explained

You have probably heard people talk about "streaming" Netflix or watching something "on YouTube." But what does streaming actually mean? This guide explains it all in plain English.

What is Streaming?

Streaming is a way to watch films, TV shows, and videos over the internet without downloading them first.

Think of it like a radio. When you listen to the radio, the music plays instantly — you do not need to buy a CD or wait for a download. Streaming works the same way, but for video. You press play, and the programme starts almost immediately.

The video travels from the internet to your screen in real time. As long as you have a WiFi or internet connection, you can watch whatever you like, whenever you like.

How is Streaming Different from Regular TV?

With regular TV (Freeview, cable, or satellite), you watch what the channel decides to show, at the time they choose to show it. If you miss a programme, you miss it.

With streaming, you choose what to watch from a huge library of films and shows, and you press play whenever you are ready. You can pause, rewind, stop halfway through, and come back to it later. It is like having a video shop in your living room that never closes.

Some key differences:

• No schedules. Watch anything at any time of day or night.
• No aerial or satellite dish needed. Just an internet connection.
• Pause and resume. Stop watching and pick up right where you left off, even on a different device.
• Watch on any screen. Your TV, phone, tablet, or computer.

Popular Streaming Services

There are several streaming services to choose from. Here are the most popular ones:

YouTube (Free)

YouTube is the world's biggest video website. It is completely free and has millions of videos — from cooking tutorials and gardening tips to music, news, and old TV clips. You do not need an account to watch, though creating a free one lets you save your favourite videos.

Netflix (From £4.99 / $6.99 per month)

Netflix is the most well-known streaming service. It has thousands of films, TV series, and documentaries. You pay a monthly fee and can watch as much as you want. There are no adverts on most plans.

BBC iPlayer (Free with a TV Licence)

If you are in the UK and have a TV licence, BBC iPlayer lets you watch any BBC programme for free. This includes dramas, comedies, news, and nature documentaries. Programmes are usually available for 12 months after they air.

Amazon Prime Video (From £5.99 / $8.99 per month)

Amazon Prime Video works like Netflix — a monthly fee gives you access to a large library of films and shows. If you already have an Amazon Prime delivery membership, Prime Video is included at no extra cost.

Disney+ (From £4.99 / $7.99 per month)

Disney+ is the home of Disney, Pixar, Marvel, and Star Wars films and shows. It is a great choice if you have grandchildren who visit, as it has a huge selection of family-friendly content.

Streaming Services at a Glance

You do not need to sign up for all of them. Many people start with just YouTube (free) and one paid service like Netflix.

How to Watch Streaming on Your Devices

There are three common ways to start streaming.

1. On Your Phone or Tablet

This is the easiest way to get started. Simply download the app (Netflix, YouTube, BBC iPlayer, etc.) from the App Store (iPhone/iPad) or Google Play Store (Android). Open the app, create an account if needed, and start watching.

2. On a Smart TV

Most TVs sold in the last few years are "smart TVs." This means they can connect to WiFi and have streaming apps already built in. Look for a Netflix, YouTube, or Prime Video button on your remote control, or check your TV's app menu.

Simply select the app, sign in with your account details, and you are ready to watch.

3. Using a Streaming Stick

If your TV is older and does not have built-in apps, you can buy a small device that plugs into the back of your TV and adds streaming. Popular options include:

• Amazon Fire TV Stick (around £35 / $40) — plugs into your TV's HDMI port and gives you access to all major streaming apps.
• Google Chromecast (around £30 / $30) — similar to the Fire Stick, lets you stream from your phone or use built-in apps.
• Roku Stick (around £30 / $30) — another simple option with an easy-to-use remote.

All of these plug into the back of your TV and connect to your home WiFi. Setup usually takes about 10 minutes.

Do I Need Fast Internet?

You do need a reasonably stable internet connection to stream, but you do not need the fastest package available. Here is a rough guide:

• Standard definition (decent quality, slightly fuzzy): 3 Mbps or more
• High definition (clear and sharp, good for most people): 5 Mbps or more
• 4K Ultra HD (the sharpest picture): 25 Mbps or more

Most home broadband packages in the UK and US easily meet these speeds. If you can browse the internet and watch YouTube without problems, your connection is likely fast enough for Netflix too.

If your video keeps stopping and starting (called "buffering"), try moving closer to your WiFi router or restarting it.

Frequently Asked Questions

Can I watch streaming without the internet?

Not in real time — streaming needs an internet connection to work. However, most paid services like Netflix and Amazon Prime Video let you download films and shows to your device ahead of time. You can then watch them later without internet, which is handy for long car journeys or train rides.

Will streaming use up my mobile data?

Yes, if you are watching on your phone using mobile data (not WiFi), it can use a lot of data very quickly. One hour of streaming can use 1 to 3 GB of data. To avoid surprise bills, always try to stream over WiFi at home rather than using your mobile data.

Is streaming safe?

Yes. The major services like Netflix, YouTube, BBC iPlayer, Amazon, and Disney+ are all safe and trustworthy. Just make sure you download their apps from the official App Store or Google Play Store, not from links in emails or text messages.

Do I have to commit to a contract?

No. Most streaming services are pay-monthly with no contract. You can cancel at any time, and you will not be charged again. YouTube is completely free and does not require any payment at all.

Getting Started

The simplest way to try streaming is to open YouTube on your phone, tablet, or computer — it costs nothing and requires no sign-up. Search for something you enjoy, like "how to grow tomatoes" or "best of Morecambe and Wise," and press play.

Once you are comfortable, you might want to try a paid service. Netflix and Disney+ often offer introductory deals, so keep an eye out for those.

Streaming has made it easier than ever to watch what you want, when you want. Once you try it, you might wonder how you ever managed with just five channels.
