【Watch The Grey Online】

When the iPhone launched 10 years ago,Watch The Grey Online it came with YouTube as a default app on iOS 1.

The pairing of the Google-owned video platform and Apple wasn't as odd then as it might seem today — the first commercial version of Android didn't debut until 2008.

But that doesn't mean that the Apple/ Google collaboration was a happy marriage. The YouTube app was created by Apple with little input from the YouTube team, which limited the video viewing experience, much to the chagrin of iOS users resorting to their mobile browser to watch video content on the platform.

That changed in 2012 with the introduction of iOS 6, which launched without the Apple-built YouTube app for the first time, after Google didn't renew its license. This allowed Google to bring its own fully realized version of YouTube to the App Store, but also meant that YouTube was no longer a default app on the phone.

At the time, it wasn't exactly clear why the split happened. My colleague Chris Taylor, who hated the Apple video player, guessed it was the result of Apple distancing itself from its rival, as it was the same year Maps came as part of the OS, too.

Now, almost five years later we have an inside look at what went down with the split.

Hunter Walk, a notable venture capitalist who was on the YouTube team back in the early days of the iPhone, shed a little more light on the story via tweetstorm, which was spotted by Business Insider. In the tweetstorm, Walk gives us some insight about exactly what went down.

You can read the whole story — according to Walk, at least — below:
