A second important event in the development of hip-hop was the start of hip-hop dance instruction. Buddha Stretch was a pioneer in this field. He started teaching formal hip-hop dance classes in 1989 at Broadway Dance Center in New York City where he continues to teach today. Around the same time, hip-hop party dancing started to appear in music videos and on television—this was another important point in the development and commercialization of hip-hop. An early example of this is when Janet Jackson performed the Running Man in her 1989 music video for the song "Rhythm Nation" which was choreographed by street dancer Anthony Thomas. The dance was so popular during this time it was also performed by 1990s rappers MC Hammer and Vanilla Ice in their choreographed routines. Michael Jackson also used hip-hop in his 1992 music video "Remember The Time" which was choreographed by a then 21-year-old Fatima Robinson. At the time, Robinson was a street dancer with no formal training and "Remember the Time" was her first music video job. According to MTV.com, "Dances have always been a part of hip-hop culture — from the running man to the Soulja Boy dance..." and this era was the start of commercial hip-hop choreography as it looks today: dance routines are not specific to one genre (strictly popping, strictly locking, or strictly breaking) but rather an of urban party dancing with studio technique added to it.
