Reporting dividends on taxes: Do I have to fill out a form for each company, or only one form per broker (aggregated total of dividends)

If I own 100 companies with dividends, that seems like a huge hassle to fill out 100 forms.

Does a broker mail me a single letter of my total dividends summed, and I only have to fill out one form during tax season?

I'm hoping the latter is the case.
