Oculus history

 oculus-history  

Here's a timeline of Oculus' history from its founding to being acquired by Facebook:

• 2012 - Oculus VR is founded by Palmer Luckey, Brendan Iribe and Nate Mitchell. Luckey creates a prototype VR headset called the Oculus Rift using a smartphone screen and lenses from a 3D TV.

• 2013 - Oculus launches a Kickstarter crowdfunding campaign to fund the consumer version of the Rift. It raises over $2 million, far surpassing its $250k goal.gpu temperature

2014 - Facebook acquires Oculus VR for around $2 billion. Many in the VR community criticize the acquisition, worried about Facebook's motives and data collection.

• 2015 - Oculus releases the first consumer version of the Rift VR headset. It requires users to tether to a high-end gaming PC to function. The headset receives mostly positive reviews.

• 2016 - Facebook announces Oculus Touch controllers to complement the Rift headset. They allow for motion-controlled interactions in VR. The Touch launches later that year.

• 2017 - Oculus releases the standalone Oculus Go VR headset, its first device that doesn't require a tethered PC or smartphone. However, it offers a more limited VR experience.

• 2018 - Facebook launches the standalone Oculus Quest VR headset. It features inside-out tracking and high-quality graphics for an all-in-one premium VR experience. The Quest is a commercial success.mini pc Chuwi

2019 - Facebook's VR ambitions accelerate under CEO Mark Zuckerberg, who calls VR "the next major computing platform." The independent Oculus website is merged into Facebook's website.

• 2020 - Facebook launches the higher-end Oculus Quest 2 for $300, further refining the all-in-one VR formula. The lower price and wireless design boost sales and adoption. However, a Facebook account is now required to use it.

• 2021 - Oculus stops independent hardware sales of the PC-tethered Oculus Rift. The company discontinues the Oculus Go headset as well. Its focus shifts primarily to standalone Quest headsets.

• 2022 - Facebook rebrands as Meta and announces its "metaverse" vision for the future of VR, AR and computing. Oculus ceases to operate as an independent brand and comes fully under the Meta umbrella.

• 2023 - Rumors surface of a higher-end Quest Pro headset, planned to launch in Q3 or Q4 2023. It is expected to feature improved specs and productivity features aimed at business users.

In summary, Oculus helped pioneer the modern consumer VR renaissance but saw its independent ambitions curtailed after being acquired by Facebook. Under Meta's ownership, Oculus has focused on developing affordable and user-friendly standalone VR headsets like the Quest line. However, many VR enthusiasts lament the loss of Oculus' early values and independent spirit. Prospects for Oculus' future now appear inextricably linked to Meta's metaverse vision.

Goldman Sachs CEO Says Apple Card the ‘Most Successful Credit Card Launch Ever’

The Apple Card got everyone’s attention with special offers and low-interest rates. It also made headlines for accepting applicants with average credit scores. As we know Apple has tied up with Goldman Sachs for the credit card. Goldman Sachs CEO calls Apple Card the ‘Most Successful Credit Card Launch ever.’

The quote was part of Goldman Sachs CEO David Solomon’s address to its investors. He further said that since the August launch the bank is witnessing a high demand for Apple Card.

In three short years, we have raised $55 billion in deposits on the Marcus platform, generated $5 billion in loans, and built a new credit-card platform and launched ‌Apple Card‌,” Solomon said, adding “which we believe is the most successful credit-card launch ever.

Since August, we’ve been pleased to see a high level of consumer demand for the product. From an operational and risk perspective, we’ve handled the inflows smoothly and without comprising our credit underwriting standards.

Apple Card is available for iOS users based in the U.S. Here is how to apply and use Apple Card. If you have already got the Apple Card then check out the best Apple Card tips and tricks.
Our Take

Apple alongsiwith Goldman Sachs is trying to change the way a credit card works. To begin with, on Apple Card you will get daily cashback, so no waiting for months to get your cashback. Thats not all, the card automatically breakdown transaction and helps you keep a track of your spending.

Once we move beyond the consumer perspective, the Apple Card seems like a very bullish bet by Goldman Sachs. The financial giant is spending as much as $350 to acquire new Apple Card users and analysts say that they might lose money. The odds of this happening increase if there is a recession in the next couple of years.Also Read:iTunes Could Not Connect to This iPhone
