Watch 200 videos. You can fast forward through the videos however you must watch commercials.
THE catch appears to be 200 unique videos. If you watch the same one again it will not count. Also it does not count till commercials at the end are done
There are a couple categories that help with this. Comedians in cars getting coffee are 10 minute shows. NOTE... Season one has no commercials. There are also about 30 of these. Then there is a bunch of interviews under shows category labeled why it crackles. These are 4-5 minutes a piece. You still must watch the commercials but you can fast forward quick. There are currently 92 of these.
NOTE...you may get an error around 3rd - 4th video. Just exit the error and continue. That video did not count and start it over.
hope this helps. Any questions ask away. Any other trends noticed add to the comments and I will update this guide.
