When you speak that way, why does it always sound you are referring to yourself?
There are more shows on streaming that I watch then on Cable/Broadcast Networks, I would assume since these services have so many subscribers and are still growing by the millions ( Netflix was the only one that lost a small amount, -200,000) they are many others that watch more then one series.
From the top of my head-
Paramount+-All the Star Treks, Evil, Seal Team, Halo, just finished The Offer, Yellowstone Spin Offs
Disney+-all the Marvel and Star Wars
Hulu-Orville, Handmaid, Solar Opposites
Netflix-Witcher, Stranger Things, Crown, Shadow and Bone, Sweet Tooth, Umbrella Academy, The Lincoln Lawyer and soon The Sandman and Resident Evil.
That is just what I remember, there are much more.
