The year was 201
At that time, YouTube was reborn. It was born in the modern, refined place where you now look, whatever you watch on YouTube. The times are good, YouTube is great and people are crazy.
But there is a catch (because there is always a catch): there was a way to go back to the old YouTube interface. Just like the crooks of the past who refused to comply with modern social rules, you too could go back in time and revolt. The Classic interface as we will call it, has been available to users since 2017, ehm.
But just like the Wild West at the turn of the century, the sun begins to set in its time. In March two thousand and twenty (2020), this classic interface disappeared forever, with only the new YouTube left.
Of course, if you embraced the 2017 makeover one day, first of all, it doesn't affect you – chances are you will forget that the classic interface once existed. But when you've put the new look in the spotlight, the time is coming – the time to meet it.
Because Google kills another unused feature. Classic.
