Many Companies Are Now Opting for Commercial Time for Live

Many companies are now opting for commercial time for live events rather than programs that consumers might watch later on DVR.Most likely the reason for this shift is

A) live programming draws greater interest.
B) people who watch live programming also have higher disposable incomes.
C) there is more impact since the commercial is only shown once.
D) people who record programs on DVRs can use remotes with "skip" buttons for ad-zapping, so the message is wasted.
E) there is less censorship when programs are aired live.
