There was once a time when the Internet was nothing but text and images. Now, YouTube is the third-largest site in the world and video has taken its place on the throne as king of the Internet. If you want to find some of the best tech content on the Web, YouTube should be your first stop.

Think about it. Technology is a very hands-on subject, and you can only go so far using text and images. Video is the clearest way to demonstrate an object's appearance and functionality. Is it any wonder why there are, for example, so many helpful YouTube channels for Apple fans?

But because there are thousands of tech reviewers on YouTube, you might find it difficult to find the good ones. Here are our recommendations. Check them out and don't be surprised if you end up binge-watching them for hours on end!

Mobile Reviews: MKBHD

MKBHD, or Marques Brownlee, is one of the most well-known tech reviewers on YouTube -- yet even with that distinction, there are still so many people who haven't heard of him. Whenever tech reviewers are discussed, his name always comes up. That's how beloved his videos are.

What's most impressive is that he's only in his early twenties and started doing his videos when he was still in his teens. He's liked mostly for his articulate speech and high production value, but has been criticized for not being in-depth enough. (Personally, I think they're plenty informative for the average consumer.)

MKBHD actually reviews all kinds of gadgets and hardware, but primarily focuses on mobile phones and tablets (both Android and Apple) and that's what most people watch him for.

Mobile Reviews: PocketNow

Michael Fisher of PocketNow is one of the most highly-praised reviewers in the Android community. Not that he only reviews Android devices -- he has covered Apple and Windows devices many times -- but Android users seem to be his primary fanbase for whatever reason.

Like MKBHD, PocketNow videos have solid production value and they're lovely to watch, but the information is backed by a healthy dose of unbiased expertise, something that's hard to find in a lot of YouTube reviewers. This is important for making good purchasing decisions that aren't driven by emotion.

Laptop Reviews: MobileTechReview

MobileTechReview is such a wonderful resource for anyone who's sick of shallow YouTube reviews. The videos on this channel are incredibly in-depth, with each review averaging around 15 to 20 minutes in length (compared to a typical review which might be 5 to 10 minutes).

Without exaggerating, I think MobileTechReview is one of the best channels on YouTube, period. Lisa Gade really knows her stuff and there's no one who can guide you better than her when it comes to making a smart mobile device purchase. She may lack personality, but some -- including myself -- may actually prefer that.

Note that Lisa covers all kinds of devices in her reviews, but her laptop reviews (and laptop comparisons) are especially good.

Gadget Reviews: OT4Tech

OT4Tech is run by Jonathan Casey, an occupational therapist who loves gadgets for all of the convenience and possibilities they offer. This channel is where he can freely express that passion in the form of gadget reviews.

His videos are somewhat jarring at first as their format is a bit different from the usual YouTube review. At times, they even feel a bit like product infomercials. But you'll get over it soon enough, and once you do, you'll see the value in what he reviews.

Camera Reviews: DigitalRev TV

Of the many YouTube channels for photographers, DigitalRev TV is notable because it strikes the perfect balance between humorous and informative. Their DSLR reviews are their claim to fame, and in terms of sheer review volume, few other channels can compete.

But the channel isn't limited to DSLRs only. They also review all kinds of camera lenses, point-and-shoots, camera bags, tripods, and other accessories that are significant enough to cover. Peppered between reviews are other videos, some which are lighthearted fun and others which are educational.

Camera Reviews: TheCameraStoreTV

DigitalRev TV might be the more fun and popular channel, but TheCameraStoreTV is where you'll want to go for in-depth camera reviews that actually show the true potential in each piece of gear.

As you'll see, their field tests are some of the most helpful videos because they show you what the camera can produce. It's not just words and specifications. You're seeing real results, which is immensely useful when you want to buy a camera but can't try it out for yourself.

So whether you're looking to buy your very first camera or you want to progress further by replacing the camera you currently have, TheCameraStoreTV will come in handy. In my opinion, the best time to watch their videos is when you've already narrowed down your choices but can't make that final decision.

PC Hardware Reviews: 3DGAMEMAN

A lot of PC enthusiasts tend to flock to the same handful of reviewers that everyone mostly knows about already -- LinusTechTips comes to mind -- but there's one YouTube reviewer who puts out quality reviews yet doesn't have a significant following. This is a travesty.

3DGAMEMAN covers all kinds of PC hardware, including headsets, mice, keyboards, microphones, speakers, network routers, and even PC tower cases. He's a gamer so the reviews are influenced in that direction, but even if you don't play games, there's a lot you can learn from his videos.

General Reviews: Tested

Tested is not a tech-centric review channel, but they do have reviews and they do cover a lot of techy things. So if you find yourself confused by their coffee and food videos, feel free to ignore them and just move onto their other awesome reviews.

Seriously, their coverage is all over the place: laptops, drones, virtual reality headsets, monitors, cameras, robots, smartphones, and more. There's no real rhyme or reason here. The Tested crew will review anything and everything as long as they think it's conceptually awesome.

Gaming Reviews: The Cynical Brit

Game reviewers are a dime a dozen on YouTube, but there's one personality that really sticks out from the rest: TotalBiscuit, also known as The Cynical Brit. The man is an iconic figure in the gaming community and was instrumental in the success of many indie games (due to his reviews).

To be clear, TotalBiscuit doesn't actually review games in the way that IGN or GameSpot do. Instead, he records himself playing and provides commentary on various aspects of said games, which you could interpret as informal reviews. Some might even say he's similar to Zero Punctuation in that regard.

Either way, if you want to know more about a game, his videos are a good place to start. Whether you like what he offers or not will depend on your own personal tastes.
