I check Instagram most days and I had never heard of Instagram TV before this post. They can't possibly have been shoving it down everyone's throats that aggressively.
You didn't use Instagram when they rolled out IGTV then. There were multiple inline promotions, aggressive hints for the dedicated IGTV button, then they made this dedicated button red (in an otherwise gray-and-white interface) for several months.
It still failed, of course, and got relegated to a small button inside the explore tab, but it the push was aggressive nonetheless. Expect the same for "Facebook's TikTok".
