Home of: The Tennessee Titans (NHL)
Cost of naming rights: $2 million a year
How bad was Adelphia as a naming partner? So bad that when the company filed for bankruptcy in 2002, the Titans' stadium in Nashville went without a sponsor until 2006.
Adelphia bought the Coliseum's naming rights in 1999, but likely didn't consider what that purchase would do to its books. The company's hierarchy hid $2.3 billion in debt from shareholders while its officers pocketed $100 million for themselves. Adelphia ended up missing a payment on the naming rights in 2002 as a result, but that was only an omen of worse to come.
