I have linked to tons of YouTube videos here on this blog. You can click on the 'youtube' tag below the post to find them all.
When I first started learning French I would watch things like Bob the builder (Bob Le Bricoleur) and Thomas the tank engine (Thomas le train) and Disney songs in French.
Now, since my French is at a fairly decent level I can understand pretty much everything (except when people speak super super fast or use tons of slang like most teenagers do)... and I've found that watching YouTube bloggers AKA vloggers really helps!
I stumbled upon this site and it lists all the Top French Youtube vloggers, by order of number of subscribers. I really enjoy the videos by the top 2, Cyprien and Norman. (I think they are friends now even though they are sort of competitors). However, now that they're both super super famous (with millions of subscribers and millions of views per video!) it seems like they don't have much time to make videos like they used to. Still, go through that list and you may find something (or someone rather) you like! :) It's interesting that all the top vloggers are male. I wonder why this is the case?

I also came across this vlogger called Rachel Martino while I was searching for videos about foreigners learning French. She has an English YouTube channel and a French one and her French one is much more popular as her Frenchie fans seem to love her. She seems really sweet and looks like Kate Hudson (to me) and coincidentally, despite being American, she also appears on the list/site I mentioned above.
