1963 was a very important year for the band as well - between them, their two albums were number one in the UK album chart for well over half the year, while they also had three number one singles in the UK (four if you count PPM), plus they released what is still the most successful EP in UK chart history and saw several Lennon/McCartney songs become hits for other artists.
They played at the Royal Variety Performance, moved from Liverpool to London, went from support act to top of the bill on their national UK tours, made their first steps towards international stardom with a successful tour in Sweden, and began making moves towards conquering Europe and America, booking appearances there for early the following year.
The Beatles Book Monthly was launched, the word "Beatlemania" was coined, and they began to get recognition from serious journalists, not just the local Liverpool press and the tabloids and teen magazines.
1963 was the year they outgrew Britain and began to make waves all around the world.
