7 There is also pay TV, known as toll TV or subscription TV, which differs from cable TV in two important aspects. Pay TV entirely originates its own programs and charge a fee for viewing each program. Nearly all TV in the U.S is commercial. So programs are interrupted every 15 minutes or so for advertisement. There is, however, one channel where there are no commercial breaks. Programs on this channel are run by the Public Broadcasting Service.

Apart from legally divorced cases there are many separated couples.
