T&P Corporation is a transnational company with four distinct businesses, including a national music and video store chain, a rap music production company, a talent agency that represents several famous rap stars, and a digital video disc (DVD) production facility that makes and records music videos on DVDs. T&P is in the process of acquiring another company, its major music store rival ReBop Records. Because its rap stars are so famous, T&P charges crazed fans a higher price for its music compact discs and DVD videos. The fans don't mind, as they often have the opportunity to meet the rap stars in person at various T&P music stores throughout the year. T&P has a policy of promotion from within as well as a no-layoff policy, and all managers are required to rotate through each business before they can be promoted.
