Oracle Arena - OaklandRecent rumors have Oracle honcho Larry Ellison, a basketball nut, considering buying the NBA's Golden State Warriors. \n\nBut for now Oracle just owns the naming rights to the Warriors' home court. \n\nPreviously known as the Oakland Coliseum Arena, the venue took on the Oracle moniker in Oct. 2006 when the Warriors and Oracle signed a \n\n10-year agreement that changed the name to Oracle Arena (financials of the deal were not disclosed). It is often referred to as "The O" and it has the \n\nlargest seating capacity of any California NBA arena, holding 19,596 fans. That's not surprising: Larry doesn't do anything in a small way.\n\nAT&T Park - San FranciscoAT&T Park, home to baseball's San Francisco Giants, changes its name more than some people change their minds. On opening day in 2000, the \n\nstadium was called Pacific Bell Park; then it became SBC Park in 2003 when SBC bought Pac Bell. The AT&T name debuted when SBC \n\nCommunications merged with AT&T in 2005.\n\nWhatever the name, this is the yard where controversial slugger Barry Bonds smashed lots and lots of balls into McCovey Cove.\n\nSeattle Sounders sponsored by Xbox 360The Seattle Sounders debuted in Major League Soccer in the 2009 season as an expansion team (Microsoft co-founder Paul Allen is one of the \n\nowners) and have a huge following in the Seattle area. Home games at Qwest Field are frequently sold out.\n\nMicrosoft quickly saw a sponsorship opportunity with Sounders and paid an estimated $20 million to plaster the Xbox 360 and Xbox Live logos on \n\nthe front of the team's jerseys. Game on!\n\nQualcomm Stadium - San DiegoIn 1997, Jack Murphy Stadium, home of the NFL's San Diego Chargers, was renamed Qualcomm Stadium after mobile phone chipmaker \n\nQualcomm paid $18 million for the naming rights. The Qualcomm money went toward a $78 million renovation project underway in '97 that added \n\n10,500 seats, 34 suites, four club lounges, upgraded food service and two video boards. In return for footing some of the bill, Qualcomm got the \n\nstadium named after it. The naming rights deal expires in 2017.\n\nPaul Allen, owner of the Blazers and SeahawksMicrosoft co-founder Paul Allen is certainly a man about town in the Pacific Northwest. The founder of Seattle-based private asset management \n\ncompany Vulcan Inc. is an investor in many other real estate, media and technology companies. And then there are the sports teams. A minority owner \n\nof pro soccer team the Seattle Sounders, Allen has owned the NBA's Portland Trail Blazers since 1988. But that's not all...\n \n...Allen also owns the NFL's Seattle Seahawks, acquiring the team in 1997. What, no baseball?\n\nThe HP Pavilion at San JoseWidely known as "The Shark Tank," the HP Pavilion at San Jose is home to the NHL's San Jose Sharks. After being called the San Jose Arena \n\nsince 1993, the naming rights were sold to Compaq and the arena became Compaq Center at San Jose. When Hewlett-Packard bought Compaq in \n\n2002, HP chose to change the arena's name. Clever points go to HP for naming it Pavilion and not "arena" given that the HP Pavilion is one of the \n\ncompany's most popular computer model names.\n\nErnie Els, the SAP manTech companies and professional golf have gone together for years, and enterprise business software vendor SAP paid top dollar in 2002 for South African pro golfer Ernie Els to be a one-man billboard out on the fairway. Els has been wearing the SAP logo on his hat and golf shirt ever since.\n\nTiger Woods to Star in Upcoming Windows 7 Commercials\n\nSeattle Storm Wear BingThis month, the WNBA's Seattle Storm and Microsoft signed a multi-year partnership to put the Bing search engine logo on the team's uniform. But \n\nwe're not talking about a discreet little logo here \u2014 BING will run across the front of the Storm's game jerseys, a space usually saved for the \n\nteam name. Neither party commented on the finances of the partnership, but Storm CEO Karen Bryant said it was the richest financial partnership in the \n\nteam's 11-year history.\n\nSeahawks Practice with BingThe Bing logo also finds itself on the Seattle Seahawks practice jerseys. The partnership was announced just before the start of the 2009 NFL \n\nseason and entails the Seahawks wearing a Bing patch on the left chest area of their practice jerseys, which will also be worn by players at community \n\nappearances. This is the first time a company's logo has been featured on the Seahawks' practice jerseys.\n\nThe Sony Ericsson Tennis OpenMobile phone maker Sony Ericsson sponsors the world's fifth largest tennis tournament, held in late March in Miami. The Sony Ericsson Open is \n\noften nicknamed "the fifth grand slam" because of its size and the fact that it's a combined event for both men and women. For 15 years it was called the \n\nLipton Championships, until 2000 when it was renamed the Ericsson Open. In 2002, it became known as the NASDAQ-100 Open. In 2007, Sony \n\nEricsson agreed to pay $20 million over the next four years for the naming rights. Game, set, match to Sony Ericsson.
