Madonna's first single, Borderline, peaked at #16 on Billboard's Hot 100 in 1983. The next, Holiday, went to #10 and was followed by Lucky Star which rose to #4. Then on December 18, 1984 her fourth single, Like a Virgin, went all the way to #1 - where it stayed for six weeks.
Virgin was the first of her twelve singles to top the charts in the U.S. (Altogether she's had 37 top-10 hits - more than any female artist). It was her risque live performance of Like a Virgin at MTV's 1st Music Video Awards in 1984 (she rolled about the stage wearing a wedding dress) that propelled her to superstardom.
