In fact, the structure these rare pineapples are grown in was unearthed in 1991 and renovated just two years later to a working state.

If one of these elusive pineapples were to go up for auction or sale, due to the rarity, ancient technique, time spent growing, and manual labor, these pineapples are worth $16,000!

Many old CPUs from the 70s, 80s and early 90s (and many modern embedded systems) have an 8 bit or 16 bit word size.

Some had different word sizes for instructions and data.

Some chips with microprocessors inside them also contain other components, and are complete single chip "computers".

Three college students, down on their luck and in rent arrears, plotted, schemed, and grafted away night-after-night in an effort to avoid having their rental lease terminated and keep themselves off the streets.

The result of all of this hard work was Airbnb, a revolutionary online marketplace for renting rooms and apartments.

This breakthrough in online lodging has become a massive success, bringing in hundreds of millions of dollars annually and operating in a staggering 192 countries worldwide.

In celebration of this momentous achievement and their more than ten years in business, here are 20 Fun Facts about Airbnb, that you probably didn't know.

With the debt piling up and the landlord on their tail, for rent arrears, Brian Chesky, Joe Gebbia, and Nate Blecharczyk, found themselves between a rock and a hard place.

With no immediate options available to them to cover their costs, the three of them got creative and decided to rent out an airbed in their apartment to budget-conscious tourists or those simply in need of a safe place to lay their heads.

This enterprise soon took off, and over time it evolved into the Airbnb we have today, with a little cheeky nod to its birth all those years ago, still in its name.

Airbnb was formed in San Francisco in 2008, and it's in that very city where Airbnb plays host to it's most loyal customers and fans, with the Sanfranciscan's on average spending five and half days in each property and splashing out a whopping $1,045 for their stay.

Before they became a massive global success and a license to print money, the company required some start-up cash.

Brian, Joe, and Nate solved this problem ingeniously by repackaging and rebranding breakfast cereals to coincide with the 2008 presidential elections.

They were a roaring success, shifting thousands of units, and securing that much-needed start-up capital.

Although Airbnb is very popular with young professionals, the fastest-growing client base for the company comes not from hip and trendy, twenty-something, but from senior citizens.

Older folk are flocking to the online marketplace, in record numbers, opting for a home-away-from-home experience, instead of the one size fits all, assembly line hotels, which often feel impersonal and lacking in charm.

Airbnb's first year was very successful for the three founders, it changed their lives that year and kept a roof over their heads, and they only had four hundred guests!

Jump forward eleven years later, and an eye-watering four hundred guests now make a booking every two minutes.

And if that sounds impressive, one of them managed to make fifteen and a half million in just twelve months.

Two million guests stay with Airbnb each night alone, making Airbnb, by far the biggest and most lucrative online rental marketplace in the world today.

They have castles, beach huts, mobile homes, and more than two thousand tree houses currently listed on the site!

Airbnb currently lists more than fourteen thousand tiny homes, ranging from garden studio apartments to lakeside cabins, igloos, caves, and small boats.

Now, in 2019, Airbnb has offices in thirty-four cities worldwide, giving them a global reach and customer service that spans every continent.

These properties don't come cheap and are often sold out year-round, so move fast if you have the option to land yourself one of these dream-come-true properties, even if it's just for the night.

Airbnb has one of the strongest customer ratings in the industry, with more than 96% of guests being happy with the site, service, and their stay.

These are the kind of number's hotels, and B&B's can only dream of achieving and is a testament to their hard work, attention to detail, and most importantly, their customer service skills.

The next year, it started work in a factory in New Jersey, lifting and stacking pieces of metal that were too hot for people to touch.

The engineers could program it, and reprogram it if they had to.

Many factories use robots to do hard work quickly and without many mistakes.

Some robots find and get rid of bombs.

People still think of robots as having a shape like a person-two legs, two arms, and a head.
