It was fairly successful in Brazil during the 1990s by playing cover versions of other bands' hard rock songs translated to Portuguese.
Their self-titled debut album, Yahoo, had the Def Leppard's hit "Love Bites" translated as "Mordidas de Amor", and was used in the soundtrack of the telenovela Bebê a Bordo.
It was not as successful as the previous ones, but two songs, "Veneno" ("Poison") and "Somos a Luz da Manhã" ("We are the Morning Light"), were used in the soundtrack of a movie, Sonho de Verão.
Yahoo released the album Pára-Raio in 1992, with several cover songs, such as "Pára-Raio" ("Lightning Rod", a version of "Hide You Heart" by Kiss) and "Como o Vento" ("Like the Wind", a version of "Wind of Change" by Scorpions); the song "Paixão Esquecida" ("Forgotten Passion") was again used in a telenovela, Deus nos Acuda.
In 1996, not long after the release of Arquivo, the band dissolves, and the members turn their attention to a new business: they set the Yahoo Studio, in Rio de Janeiro, which would be one of the most popular recording studios in Brazil.
