Have you heard of the saga of the puppy channel?

A man had collected hundreds of hours of VHS tapes of cute pets and embarked on a mission to create a broadcast channel featuring no ads, just cute videos. Everyone turned him down, not interested, offended even at the notion that one would need a break from ad-mediated drama-laden television

One of the local cable channels growing up was a fish channel-- Somebody shot a few hours of footage at a local aquarium[1] and they ran it constantly on loop with a soundtrack of classical music.

For awhile, Reddit did pretty well with "cat pictures".

The front page has been compromised for many years, but there's still corners like:

Sadly the reposting (and mislabelling, and potato-ing) has gotten absolutely insane across the board so it’s quite a bit less enjoyable than it used to.

My wife and I still occasionally break out into a song of "Puppies, puppies, puppies, puppies, puppies, puppies, puppies, puppies, puppieeeeees!"

"Natalie Portman & Rashida Jones Speak Out Again"
