Worried about Brian Williams at NBC? How about the whereabouts of Fox's Bill O'Reilly during the Falklands War? Don't worry. Advertisers will still go where viewers head -- in spite of anything else.

Big-name Olympic athletes will probably be seen more off-the-field during the 2016 Summer Olympics in Rio de Janeiro. That's because the International Olympic Committee is softening its rules about advertising, which previously prohibited athletes from being part of "generic" or "non-Olympic" TV advertising during the games. That will mean more promotion and compensation for athletes, possibly even more so for big TV advertisers such as Coca-Cola.
