From the article quoted above:
Wait just a minute ! A GM car was just awarded as a prize for the winner of the 2nd part of a competition on Big Brother All Stars ! Um ... they had it hanging from the ceiling during the competion ... with smoke and lasers ! So they can't get it to an island ... and hanging from the ceiling is a good way to integrate their vehicles into story lines ? What hogwash !The mass exodus was led by General Motors Corp., which stayed with "Survivor" for 12 seasons and was its largest sponsor last year, spending some $20 million on the program. Spokeswoman Ryndee Carney said it wasn't due to the format, but the reason she gave wasn't a ringing endorsement for a program showing signs of wear. "We're more interested in integrating our vehicles into the storylines of TV shows or film," she said. "We just ran out of ways to do that given the format of the show being set on an island." GM's pullout was first reported by TVWeek.com.
