It was January, 1964 when the Beatles began their domination of the American Top 40 radio.  I was doing the DJ thing back then and it was quite the experience.  My station (KTEO in TX) had played one of their early VeeJay releases around September of 1963 and it was on our playlist about a week with no audience response.  Interestingly one of my USAF buddies had mentioned the Beatles to me about that same time.  He had been stationed at our base in Scotland so he had witnessed the impact they had on the U.K. and wondered why he hadn't heard them in the U.S.  What fun it was being a DJ then.  The audience was really listening and phoning in their requests, especially when yet another British group showed up.  I doubt we'll ever see a time like that again but I certainly am glad I got to play the hits when it was really fun!
