Many listeners of podcasts are doing so while multi-tasking. Text based would be requiring direct attention that I don't think would win over the vast majority of people.

You're right. I got this from AI.

Based on research, a significant majority of podcast listeners—up to 94%—multitask while tuning in, with about 59% doing so regularly. Podcasts are often chosen because they allow listeners to consume content while their hands and body are occupied with other tasks.

But even 6% to 41% of the market is still alot.
