You obviously don't understand the meaning of the words "BUYING AIRTIME ON TV"
Advertisers(like Coke, Progressive, etc.) pay dollars to air commercials on programs and
Selling air time to advertisers generates much of the income the media need to function.
Do you know what i mean?
Remember ATS is not the advertiser.
But doesn't that mean that the agency (ATS) pays the network (NBC) for the TV spot, then tries to make up the difference (and hopefully a profit) by selling directly to advertising companies (i.e. South Korea tourist agency, East-west bank)?
