<title> tags were rendered in Internet Explorer as a tooltip. Other browsers would only render the alt tag as a tooltip, but there was pressure on them to also render the <title> because IE was the dominant browser at the time.
You're confusing the title element with the title attribute.
Where would a <title> display as a tooltip? And how would that render the <sup> tags like in the <title> on this page?
