Considering how the iPhone is losing some major steam, Apple is going to need to find some more sources of revenue if it wants to continue to be as ridiculously successful as it has been in recent years. The company already secured a chunk of the growing wearables market with the Apple Watch, but that’s not going to be enough, which is why there’s speculation that Apple will enter other emerging markets like drones and virtual reality in the future. While there’s nothing in the way of official confirmation that this will happen, CEO Tim Cook did drop some hints that his company is interested in virtual reality during Tuesday’s quarterly earnings report.
