Reporting on Webinar Registration by Program Name

This is possible with Program Performance report. In the setup you can add filters of Channel, then check the box for 'Show program status columns'. Then you'll have a report of all your webinar programs and the count of people in each status.

The visuals in the support doc aren't so clear on what you get as the end product, but it should be something like: 

I prob copied the wrong one. Maybe this is it: 

<script src="//app-ab37.marketo.com/js/forms2/js/forms2.min.js"></script>
<form id="mktoForm_1056"></form>
<script>/*MktoForms2.loadForm("//app-ab37.marketo.com", "525-EAQ-286", 1056);*/
MktoForms2.loadForm("//app-ab37.marketo.com", "525-EAQ-286", 1056, function (form) {
form.vals({"lastFormReferralURL":document.referrer});
});
</script>

Thanks for sharing this. I recently added a new field called "webinar name" and we pass the name as a hidden value. I can group the report by webinar name, then I added custom columns for "live webinar" and "on-demand". We are able to see the data now but I remember it not being accurate (it didn't seem accurate before and i"m showing on-demand reg for a webinar that hasn't happened yet). Still, it is promising. There is a funky "empty" field which I don't know what to do with. 

I had that same use case this morning coincidentally.

It would already help if the custom columns feature of the People Performance Report could also be made available for the Program Performance Report, so you can configure it yourself.
