Phil and Dan --> Dan and Phil
They didn't start off as "Dan and Phil". In the beginning when a name had to be picked to go first, it would always be Phil's, because he was the more popular of the two and the one who became a youtuber first. This can be seen in older videos such as "A Day In The Life of Phil and Dan!" and "PHIL AND DAN LOVE STICKAID!"
Phil on the right, Dan on the left - when did it happen?
Just as with the names, Dan always being on the left side of Phil in videos didn't just happen naturally, it was a conscious choice. In this case the decision seems to coincide with them starting the Superamazing Project - weekly episodes where they had to work together regularly for the first time. In the first few episodes they switched places like it didn't matter, but after that they seem to have decided on an order.
