Things always make one show

Actually this looked much cooler in my head when first imagined...
But, here it comes:

There is always one thing, which always returns to the scene of every TV show or series, which can be called THE thing, making the show.

I have started this collection, since it has been just a quick idea, I doubt I will extend it. Some explanation should follow though:

Dallas - Whiskey glass
EZEL (Turkish series) - Mobile phone (never seen any other show, where mobile phones were used this often...)
Werner (Beinhart) - Beer
House (MD) - Vicodine
Kojak - Lollipop
Columbo - Cigar

Resources used: Except for "Werner", everything is an own creation of all the show titles, including the symbols.
