On Monday, President Clinton signed into law the much-discussed 'Must-See TV' bill, which requires all Americans to watch NBC's Thursday-night prime-time line-up. 'With the signing of this bill, the phrase 'Must-See TV' is no longer merely a strong suggestion by NBC; it is a federally backed order,' Clinton said. The president stressed that under the new law, viewers would be required to watch not only the top-rated, Emmy-winning programs Seinfeld, Friends and ER, but also 'all of the crappy programs sandwiched in between.' Failure to watch Must-See TV will result in fines of up to $250,000 and up to 10 years in federal prison.
