In 1984, network television commercials accounted for 80% of all network and non-network television advertising revenue. In 2004, that figure was 60%. During that same period, operating cost for the networks remained steady, and in 2004 every major network announced record setting profits.

The information above, if true, supports which of the following conclusions?

A) Between 1984 and 2004, the number of homes with access to non-network television channels increased by more than 20%.
B) Teenagers comprise a growing proportion of television viewers, and teenagers prefer to watch non-network television shows.
C) The amount of advertising revenue earned from non-network television commercials in 2004 was greater than the amount of revenue earned by network television commercials in 1984.
D) Between 1984 and 2004, advertising revenue earned from non-network television commercials grew at a faster rate than revenue earned from network television commercials.
E) Soon revenue from non-network television commercials will surpass revenue from network television commercials.

___________________________________________________
Correct Answer: D

I don't quite understand the stimulus here. Does network television commercials equal to network television advertising revenue? Are the two concepts the same thing? If they aren't, how do you solve this problem. Many thanks~

BTW:I am your fans!

There are two types of broadcasting systems: network and non-network; both carry TV commercials and have advertising revenue.

Total revenue = revenue from non-network + revenue from network.

In 1984, the advertising revenue from network TV commercials accounted for 80% of the total revenue (of both network and non-network)

In 2004, the advertising revenue from network TV commercials accounted for 60% of the total revenue (of both network and non-network)

Apparently, revenue from non-work TV commercials grow faster than that from the network

Simple math.
