Because of your comment I googled and came across the company Saatva. I was surprised to see that it is actually a fairly big company which had a revenue of $375 million in 2019. Podcast marketing must be really effective.
unless this is sarcasm, that is a glaring cause and effect error. consider that maybe already large companies are the ones with money to blow on podcasts.
I bI don't own a TV and blocked pretty much all online advertising in my life.(thanks to nextdns) However am an adamant podcast listener, most days it is probably the only advertisements that reach me.
