Maybe Data forgot to mention, after 2040 people got their entertainment solely from the internet.
I think in 1987 television was considered strictly light entertainment, there was nothing like Sopranos or Breaking Bad, there were mostly network sitcoms and procedurals. So saying we got tired of that is just an extension of saying we stopped caring about frivolous distractions.
Are you saying that Breaking Bad and The Sopronos aren't frivolous distractions? TV these days is no less "frivilous" than it was back then, don't kid yourself.
