Are actors becoming salesmen?

Product placement may seem as an innocent trick. But is it really that honest?
We all know that product placement is booming business.
Most reality shows are writing products into the story lines as a way to attract big money but the integration of commercial products into a script actually forces the actors to do are say things they aren't payed for.
Actors want to play a role in a movie or in a television soap, but do they really want to promote that new Chanel lipgloss?
Patrick M. Verrone, president of the Writers Guild of America, explains the evolution of publicity on television.
At first, product placement was used in reality TV, because it's easy for writers to get this kind of material in there and they don't have union protections.
Nowadays, you also find it on prime-time series.
According to some people, product placement is dishonest advertising.
The problem is that there aren't any specific rules, so who's to blame ?
