Television: Regulation and Competition
•Prime Time Access Rule (PTAR), 1970: Limited networks programming in prime time.

•Networks own some stations (limited now to 35% of the population). Affiliates are contractually obligated to air network programs, but are independent of the networks
•First run syndication: Independently produced programs sold on a market-by-market basis (such as Oprah and Xena: Princess Warrior. May be cash sale, barter, or cash and barter. StrippingStripping: syndicated programs aired five times per week at the same time.

Ratings and Shares:
The cost of advertising time is based mostly on the rating and share of that time slot (generated by the program):
Rating = % of Total Television Homes (TT)% of Total Television Homes (TT) (This figure will always be less the 100% total for the time slot: not everyone has a tv set on)
Share = % of Homes Using Television (HUT)% of Homes Using Television (HUT) (This figure must total 100% for all programs in the time slot)
