Emma Walsh here, managing editor of the Journal. Routine Diary readers know that tech isn't our usual beat. And when it comes to tech investing, we leave it to the experts. Fortunately, we have numerous such professionals in our Rolodex. Our coworker Jeff Brown will be familiar to our long time readers.
In truth, he had numerous triple-digit returns in his Brownstone Research study portfolios last year. Here's what Jeff believes the tech sector will bring us in 2021 Each year, I like to have a look at the big image and predict what's just around the corner. Longtime readers of my work know that I follow the most amazing tech trends on the brink of mass adoption.
These trends are experiencing exponential development and producing unbelievable chances for investors. I wish to ensure all our readers are gotten ready for what's next. And with that in mind, let me draw the image of what I see being available in the next 12 months 1. 5G Devices Our brand-new 5G (fifth-generation) cordless networks are a topic I have actually been covering for years now.
Even though the COVID-19 pandemic interrupted supply chains last year, an impressive 250 million 5G-enabled devices were still sold. Especially in the second quarter, there were supply chain interruptions, making delays, and work interruptions. And all of this eventually led to Apple delaying the release of the 5G-enabled i, Phone 12 by 2 months.
When you think about all of that, selling 250 million systems is remarkable. More notably, the delays triggered by the pandemic created a heap of pent-up demand. Which demand is now going to be pushed into 2021. In reality, I anticipate that more than 500 million 5G gadgets will be shipped in 2021.
Phase Three of 5G When I've discussed 5G in the past, I have actually described its three different phases. In Phase One, the infrastructure of these new networks is built out, including all the brand-new towers and fiber-optic circuitry that 5G will require. In Phase 2, 5G gadgets go on sale.
And in Phase 3, 5G services begin to be offered. That's when we begin to see applications running on 5G networks. Consider things like huge multiplayer games over a mobile phone. That's not possible with 4G. It will be with 5G. And my second 5G forecast for 2021 is that we will start Stage Three by this summer.
More and more consumers will go out to purchase a 5G phone to access these applications. 5G is going to open up a suite of amazing applications: self-driving cars and trucks, the Web of Things, robotic surgery, and more.
The investment opportunities going forward will be massive. 3. CRISPR Genetic Editing Stepping away from 5G, the next important innovation I visualize in 2021 is CRISPR genetic editing. CRISPR stands for "clustered frequently interspaced short palindromic repeat." It's a mouthful. However it is among the most exciting developments in biotechnology.
