The incredible shrinking commercial

The headline of this AP news story is "TV commercials shrink to match attention span."

If we're lucky, the population's attention span will soon get so short that there will be no commercials at all (or, put more correctly from a mathematical point of view, the number of commercials will approach a limit of infinity and the time spent airing them would approach a limit infinitesimally small).

It's a Sarah Palin world we live in.
