Product placements in television shows where the ad becomes part of the fiction.
I officially stopped watching Eureka when there was an episode about Degree For Men. I similarly gave up on Bones when the characters started delivering Toyota ads to each other.
I’m okay with there being a stick of Degree For Men label out in Sheriff Carter’s bathroom, or if the cast of Bones drive Toyotas. But when they stop to talk about long lasting anti-wetness or zero percent APR financing I’m fucking done.
