96% of American households have a TV, 87% have a smartphone

"Smartphones continue their meteoric popularity and are now owned in 87 percent of U.S. homes, second only to televisions at 96 percent ownership, according to new Consumer Technology Association (CTA) research. CTA’s 20th Consumer Technology Ownership and Market Potential Study also shows that for the first time, the top three most-frequently owned tech products are now screen devices, as laptops – trailing only TVs and smartphones – reached their highest ownership level ever at 72 percent.
[...]
Among new, emerging tech categories, smart speakers including the Amazon Echo and Google Home have nearly tripled in ownership rate to reach 22 percent of American households, making it one of the fastest-adopted technologies since tablets. Smartwatch adoption continues to grow, with 18 percent of U.S. households now owning at least one of the devices – an increase of six percentage points over last year. Additionally, ownership rates of drones and virtual reality (VR) headsets were measured at ten and 11 percent of households, respectively.
Consumers Remain Focused on The Big Screen
Next-gen screen technologies and the availability of larger screen sizes drove more U.S. consumers to buy technology in and around the TV. 4K Ultra High Definition televisions experienced the largest growth in household ownership rate, rising 15 percentage points year-over-year to reach 31 percent households ownership, and one in five (19 percent) households owns a TV with a screen size of 60 inches or bigger. Ownership of digital media streaming devices rose nine percentage points since last year to 45 percent of households."

The Apple Watch can detect diabetes with 85% accuracy

"According to Cardiogram founder Brandon Ballinger’s latest clinical study, the Apple Watch can detect diabetes in those previously diagnosed with the disease with an 85 percent accuracy.
The study is part of the larger DeepHeart study with Cardiogram and UCSF. This particular study used data from 14,000 Apple Watch users and was able to detect that 462 of them had diabetes by using the Watch’s heart rate sensor, the same type of sensor other fitness bands using Android Wear also integrate into their systems.
In 2015, the Framingham Heart Study showed that resting heart rate and heart rate variability significantly predicted incident diabetes and hypertension. This led to the impetus to use the Watch’s heart rate sensor to see if it could accurately detect a diabetic patient."

Apple sold $5.5bn worth of 'other' hardware products - inc watches and earpods - in Q4 2017

"Other than its iPhones and computers, Apple sells a bunch of other products, like the AirPods, Apple Watch, Apple TV, Beats products, iPod Touch and, most recently, the HomePod. In Q1 2018, Apple saw $5.5 billion in revenue for these other products, an increase of 36 percent year over year.
That increase suggests Apple’s Watch Series 3, which it launched this past September, and its AirPods are selling well.
In Q4 2017, Apple sold just $3.2 billion worth of other products. To be clear, these revenues do not include pre-sales for the HomePod, which starts shipping February 9 for $349."

Nearly 20m Apple Watches were sold in 2017

"Why is Apple Watch sales momentum growing? My theory is that consumers are starting to see a place for Apple Watch in their lives. While Apple's revised Apple Watch marketing campaign around health and fitness has led to a clearer sales pitch, I think the health and fitness messaging ends up being Apple's way to get its wrist in the door. People aren't buying and using Apple Watch just for its health and fitness monitoring features. There is something more at play here.
Close to 20 million people bought an Apple Watch in 2017 because the device has become a bridge between the present and future. By including a screen, Apple Watch retains the familiarity found with smartphones, tablets, and laptops/desktops. At the same time, Apple Watch is giving wearers a glimpse of the future by introducing new ideas around how artificial intelligence, voice, digital assistants, and smart sensors can come together to produce a new kind of experience.

Apple shipped an estimated 322m devices in 2017

"It's easy to think of Apple as just an iPhone maker. More than 210M iPhones are sold per year, and no other Apple product comes close to surpassing iPhone in terms of unit sales. However, iPhone is only one piece of Apple's hardware story.
According to my estimates, Apple sold 322M gadgets in FY2017. This total includes unit sales from every major product category and accessory powered by Apple software (iPhones, iPads, Macs, Apple Watches, AirPods, iPods, Apple Pencils, Beats headphones, and Apple TVs). After a down year in 2016, when Apple shipped 8% fewer devices than in 2015, the company returned to unit sales growth in 2017. In fact, Apple shipped 7% more devices in 2017 than in 2016."

Apple is now the largest watch maker in the world, by revenue

"Traditional watchmakers, be very afraid. Apple has announced that it is now the biggest watchmaker in the world replacing Rolex at the top of the list.
Tim Cook revealed the big news alongside the unveiling of the Apple Watch Series 3, which comes packing LTE as was expected.
Apple had already reported that it had a 50% year on year growth for Watch sales, something that Cook made reference to at the 12 September event. We still don't know exact sales figures, but it's not the Apple way to talk numbers.
That's pretty impressive though when you consider that the first Apple Watch launched in 2014, while Rolex has been making watches for a fair few more years than the Cupertino company.
Moving to the number one spot also puts Apple ahead of Fossil, who have been making a big push with smartwatches and hybrid smartwatches over the past year as well as luxury watchmaker Cartier and Omega."

Smart watch shipments 'have overtaken Swiss watch shipments'

"According to research from Strategy Analytics, global smartwatch shipments reached 8.1 million units in Q4 2015, compared with 7.9 million Swiss Watch shipments. It is the first time ever that smartwatches have outshipped Swiss watches on a global basis.
Cliff Raskind, Director at Strategy Analytics, said, “We estimate global smartwatch shipments reached 8.1 million units in Q4 2015, rising a healthy 316 perc ent from 1.9 million in Q4 2014. Smartwatches are growing rapidly in North America, Western Europe and Asia. Apple Watch captured an impressive 63 per cent share of the global smartwatch market in Q4 2015, followed by Samsung with 16 per cent. Apple and Samsung together account for a commanding 8 in 10 of all smartwatches shipped worldwide.”
Steven Waltzer, Analyst at Strategy Analytics, added, “We estimate global Swiss watch shipments reached 7.9 million units in Q4 2015, falling 5 per cent from 8.3 million in Q4 2014.  Global demand for Swiss watches is slowing down, and major players like Swatch are struggling to find growth.”"

5% of US broadband households use a smart watch with health & fitness tracking

"Research firm Parks Associates announced today that 5% of U.S. broadband households use a smart watch with health and fitness tracking functions, while 8% use a digital pedometer or fitness/activity tracker. Tejas Mehta, Parks Associates’ research analyst covering the mobile and wearable markets, is attending Mobile World Congress next week in Barcelona to support the event and share the firm’s insights in wearable technology adoption trends and mobile consumer research.
“Though increased adoption of smartphones is fueling the mobile revolution that includes wearable devices, consumers' all-encompassing desire to use smartphones in all aspects of their lives is creating a dilemma for wearable OEMs,” Mehta said. “In the case of smart watches, these devices are regularly marketed as companion or ‘tethered’ smart products. Companies need to rally consumer interest in smart watches by educating them on the unique experiences and benefits of these and other wearables. Otherwise, the majority of consumers may not see the reason to purchase another device that has similar, if not the same, capabilities as their smartphone.”"

Pebble has shipped more than a million smart watches

"While Google and Apple have been getting the lion's share of attention for smartwatches lately, indie darling Pebble has been quietly soldiering on, improving its product and selling watches. In an exclusive interview, CEO Eric Migicovsky revealed that the company shipped its one millionth Pebble on December 31st of last year. That's more than double of what Pebble reported in March, indicating that price cuts and new feature additions later in the year successfully boosted sales figures."
