There's product placement in some programmes, for example the Netflix-produced House of Cards contains jarring product placement for the Playstation Vita.
There is a lot of product placement in most TV shows this was just poorly done. If someone says a brand name or you see a logo long enough to read it than chances are that's product placement. EX: Someone's drinking a beer/soda I'd you see the label it's deliberate.
There are not ads on Netflix. I wasn't being clear enough. I meant that if there are video on demand services like Netflix without ads then people will see ads as a discomfort in vod services with ads, like Hulu.
