OnSmash.com

OnSMASH, previously OnSmash.com, is a hip hop blog founded by Kevin "Hof" Hofman, a native of Long Island. It is a part of the blog family New Music Cartel (NMC).OnSMASH LLC, the corporate entity, has its headquarters in Huntington, New York.

The website was founded in 2006. Vibe described it as a "hip hop YouTube".

OnSmash.com was the original outlet to post material from rappers like Cam'ron and 50 Cent engaging in beef that had not yet been reported through mediums like BET and MTV. Lee Q. O'Denat, the founder of WorldStarHipHop, used the setup of OnSmash.com to make his own website, hiring coders to steal the source code of the original OnSMASH player. O'Denat said that this led to tension between the two websites. The site focused on fight videos and unadulterated content that had nothing to do with music, unlike OnSMASH, which kept its ear for new talent and only posted music and videos to better the culture.

Before OnSMASH was a blog, the forums served as a big part of the rap Internet. Users all gathered to talk about music, share music and post funny things from their lives. It birthed many interesting topics and characters, making OS the hub for culture on the underground level way before blogs. The community grew strong and currently holds over 2 million posts to date.

On November 25, 2010 (Thanksgiving), the United States Immigration and Customs Enforcement seized the domain name due to allegations of selling of counterfeit goods and piracy. Hofman initially believed that hackers had removed the site, but he later learned that the U.S. government had taken it down. Ben Sisario of The New York Times said "OnSmash.com and the handful of other music blogs shut down by the government post brand-new songs and videos without licenses, but much of that material is often leaked to them by managers, music labels and even the artists themselves." Alvin Blanco of MTV said "Reaction to the over-zealousness of authorities in shuttering the website last Thanksgiving Day was swift, with artists and fans bemoaning the fact that an outlet for new music from up-and-coming acts was unfairly targeted."
