Final answer:
Prior to February 1964, the Beatles had minimal exposure in the US, mainly through local radio stations and a few charting singles, unlike extensive touring or national TV appearances.
Step-by-step explanation:
The Beatles' presence in the US prior to February 1964 was minimal. Before their iconic appearance on The Ed Sullivan Show and the start of Beatlemania, they had limited exposure in the country.
Their early presence consisted of minimal exposure on local radio stations with a few of their singles entering the charts.
Unlike other rock 'n' roll artists such as Elvis Presley who saw extensive touring and national TV appearances, The Beatles' presence in the US was confined mainly to radio plays of their music until their breakthrough on national television.
