It's a common practice around the world to speed up TV shows in order to insert more commercial time. The subtle speeding up can slice a couple of minutes from a 22 minute sitcom with little noticeable difference--and broadcasters can plug in two more minutes of commercials per half hour! It's a last ditch effort, perhaps, to extract money out of a dying media delivery system before streaming obliterates the advertising model. TBS does it with Seinfeld reruns (see below) and worldwide it happens all the time--from the BBC to India.
But is that all there is to it--trying to make more money? Actually many viewers point out that TV shows (and everything else) move faster now in the age of the 6-second Vine. The speeding up actually helps the content itself seem more contemporary. Here's one commenter: "Honestly, shows move a lot faster now and the sped up version feels a little more updated than the original slower version. But who even watches actual TV anymore? No TV + adblock on 90% of internet = very little advertising = happy me :)"
