TV's "Monk" and hidden BNSF logos

[nachoman]

I have wondered about that. Sometimes when I watch a home improvement show, such as "this old house" they will cover up the brand name of the product they are using with electrical tape, or be careful not to show the part of the tool that shows the brand name. I have assumed it is because the manufacturer of that product is not a sponsor of the show, and other sponsors do not want their competitors' logos to be aired. Or, perhaps it is the producers of the show trying to encourage more sponsors (if you sponsor us, your logo could be seen here). I also remember during drama or sitcom tv shows, characters would be drinking from pepsi cans that would simply say "cola".
