trademark disputes with Bally Gaming International over its slot machines, Monster Slots, with Hansen Beverage Co. for its Monster Energy drink, and the Chicago Bears, who use the nickname "Monsters of the Midway". Other trademark disputes include a 2001 lawsuit against The Walt Disney Company for products related to the film Monsters, Inc., and a claim against an online used clothing retailer, MonsterVintage LLC. In 2004, Monster filed a complaint about the trademark application from Snow Monsters, a video website with skiing content for kids. The Snow Monsters owner initiated a lawsuit against Monster pre-emptively. It has also had a trademark dispute with the job site, Monster.com. In 2006 Monster brought a suit against Monster Mini Golf, a company selling franchise Mini Golf locations throughout the US. After an unsuccessful legal mediation, Monster Mini Golf launched a grassroots campaign against Monster Cable on the Internet. As a result, Monster received more than 200 complaints from the public. Monster Cable dropped the lawsuit and agreed to pay up to $200,000 of Monster Mini Golf's legal fees. In 2009 Monster Cable CEO Noel Lee said on Fox Business that the company has had to balance their trademark protection efforts with the public's point-of-view. Headphones Monster established a partnership with rap mogul Dr. Dre and Interscope Records in 2007 to design and manufacture the Beats Electronics line of headphones called "Beats by Dr. Dre". This led to a trend among headphone manufacturers to create celebrity-endorsed products. Monster created similar partnerships with Lady Gaga for the Heartbeats brand of headphones in 2009, P. Diddy's Diddybeats in May 2010 and LeBron James later that year. In 2010, Monster began developing a series of products for the Chinese market that were co-branded with basketball player Yao Ming. According to analyst firm NPD Group, the Beats brand that Monster distributed exclusively grew to own 53 percent of a $1 billion headphones market. A 51 percent interest in Beats was sold to HTC in August 2011. At the end of the five-year agreement between Monster and Dr. Dre in 2012, Dre decided not to renew. According to Bloomberg, both parties said the separation was "amicable" but they had disagreements on who deserves credit and the share of revenues. The partnership was responsible for a substantial portion of Monster's revenues. After the split, Monster created its own headphones product line and other celebrity-branded headphones with music groups Earth, Wind
