Under construction!
In the nearly 20 years I've been using the internet, I've found a lot. A LOT. of stuff. Here is where I want to share it!
Digital Decommercialization - How To Block Ads On The Internet - https://blog.amberdevs.gay/how-to-block-ads-on-the-internet/
Really simple and straightforward guide aimed at the less tech-familiar. Share it with someone you know who drowns in ads!
uBlock Origin - https://ublockorigin.com/
This is the one single thing I believe everyone online should learn how to use. This is it right here.
Not only is it for ad blocking, but you can also select elements from pages to get rid of forever (most, not all) (see Digital Decommercialization - How To Block Ads On The Internet in the above section).
You can also add filters, disable custom fonts, disable javascript, etc. Very very very good.
AVID - Audiovisual Identity Database - https://www.avid.wiki/Main_Page
So, so, so many TV bumpers and splashes. This is an incredible database of media that I've consulted a few times for my own projects. Also cute mascots!
It has a "Random Page" button which is fantastic. Test cards, warning screens, radio jingles... god, I've only barely scratched the surface of this thing... it's got rainbow motifs everywhere, what am I doing?
