Which at the time were garbage because of the limitations with browser support. Back in the 90s and even early 2000s, the most reliable way to do HTML chat services was via frames refreshing. Which is why many chat services ran as Java applets or (later on) as Flash. Thankfully we now have a whole array of better technologies available and wider support for them. So we're not as reliant on browser plugins nor native clients (though frankly I still prefer native clients).
