The group began a relationship with Simon Fuller of 19 Entertainment and finally signed with him in March 1995. During the summer of that year, the group toured record labels in London and Los Angeles with Fuller and finally signed a deal with Virgin Records in September 1995. From this point on, up to summer 1996, the group continued to write and record tracks for their debut album while extensively touring the West Coast of the United States, where they had signed a publishing deal with Windswept Pacific. On 7 June 1996, the Spice Girls released their debut single, "Wannabe", in the United Kingdom. In the weeks leading up to the release, the video for "Wannabe" got a trial airing on The Box music channel. The song proved to be a global hit, reaching number one in 37 countries, becoming the best-selling single by an all-female group of all time. Shortly after "Wannabe"'s release, each member of the group received a nickname from "Top of the Pops" magazine. Because of her "liveliness, zest and flaming red hair", Halliwell was named "Ginger Spice". "Wannabe" was followed by nine further number-one singles from their albums "Spice", "Spiceworld", and "Forever". Other successful releases followed, including "Say You'll Be There" and "2 Become 1" from "Spice", and "Spice Up Your Life", "Too Much", and "Viva Forever" from "Spiceworld".
