Jack Valenti, the president of the Motion Picture Association of America, calls a proposed universal ratings system unnecessary, Variety reports.
The National Institute on Media and the Family recommended the change last month in a letter to Valenti and Capitol Hill politicians, urging the use of a new universal code covering films, TV shows, music and video games.
Representatives from both the American Medical Association and the American Psychological Association signed the letter.
Valenti wrote back arguing that the majority of parents are satisfied with the current MPAA ratings system and called the change unwieldy, considering the hundreds of TV shows and songs that hit the market each week.
Sen. Joseph Lieberman (D-Conn.) is expected to convene a hearing on the universal ratings proposal later this month.
