A 'Friends' shoot night could extend well into the small hours of the morning.

The writers and actors on 'Friends' were notoriously particular about what made it onto the air.

While 'Friends' was about a 20-something population and what they were going through, they were also dealing with issues with their family.

When we developed the 'Seinfeld' show, we took a bet on Jerry Seinfeld, who was not a household name. But Jerry had a voice. He was appearing on 'Late Night', on 'The Tonight Show', had some commercials out there, his voice of observational comedy, looking at the world around him, that voice was really starting to come into its own.

One way in which 'Friends' did resemble 'Seinfeld' is that it really found its audience over the summer of 1995 in reruns. That's when the main title song, 'I'll Be There for You', by the Rembrandts, exploded, too.

What Must-See T.V. was all about was one network, one night, for one decade. And a third of the country would come and watch Must-See T.V. And you didn't dare go to work the next day, because if you hadn't watched, you would be left out of the conversation, that water-cooler conversation.
