The amount of bad language on US TV has been condemned by a watchdog group.
Swearing in televised movies is of concern to watchdogs
A study of the major broadcast networks by the Parents Television Council found a jump in profanity on "virtually every network".
It called on the TV industry to reduce what it called "the flood of vulgarity".
The results mirror the findings of a similar UK survey in July which found that the use of bad language was also increasing on British TV.
That report - by Mediawatch-UK - said that the "f-word" was used almost 1,500 times in films on the five terrestrial channels during the first half of 2003.
In the US, the Parents Television Council said broadcasters had "attempted to rewrite the book on language standards for television".
In a study of all primetime entertainment series from a two-week period in 1998, 2000 and 2002, it found a jump in profanity on "virtually every network" and in every time slot.
The study examined ABC, CBS, NBC, Fox, WB and UPN.
During the so-called "family hour" from 8pm - 9pm, it found that "foul" language increased by 94.8% between 1998 and 2002. It rose by 109% during the hour from 2100.
ABC and Fox declined to comment on the findings.
