30 Rock + TV Tropes
↳ ’Product Placement’ #1:
The practice of prominently displaying or talking about a recognizable product in a program, in exchange for some consideration from the manufacturer, usually monetary. This trope isn’t always invoked for mercenary reasons though. For example, many times it just wouldn’t be plausible for a character in a shopping mall to walk past nothing but unnamed Brand X.Real brands add veritas in such cases. Sometimes, a brand mention is presented so blatantly, it’s obvious that they’re contractually obligated to add it in. This is called an “enforced plug”.
(The gratuitous McFlurry references in episode 3x11 actually weren’t for pay, as many people thought [x]. Fey and the writers just like McFlurries. The situation was parodied a few episodes later in 3x19, involving Liz’s new Slanket.)
