pushing information to an open web page

Question

I want to push information on to my web page in real time. for example, if I have a ticker that counts the number of people who have visited my site.

I want that ticker to change whenever someone o open s the page in real time without having to refresh the page.

I imagine that this could be done using ajax and checking for updated information every few seconds and them updating the page asynchronously... but I feel like there is an easier way.

Is there a technology I could use to accomplish this task?
