Search YouTube for "B&H Event Space + [photo genre]." You'll find hour-long presentations by photographers on that genre. Wedding, sports, portrait, all kinds of great stuff.
I do mostly Landscape and Milky way photography just for the hobby.
Examples:
There is a B&H Event Space channel, but I find a lot of the videos are still on the main B&H channel. So it's easier to find videos with a YouTube search.
Hope this helps.
