CHICAGO (CBS) -- Celebrating 30 years of helping Chicagoans in need.

StreetWise magazine was founded on this day in 1992 and on Wednesday today its staff held a celebration at its headquarters  and at Union Station.

The award-winning, independent news source is the nation's longest-running street publication, but StreetWise is more than a magazine.  

It's a social enterprise helping people experiencing homelessness and those at risk. StreetWise has 115 active vendors who make around $2.00 for every magazine they sell, plus tips.

"They saw me and they helped me when I thought there was no help. So it's like, I wouldn't turn my back on them," said vendor Kianna Drummond. "Even if I do find another job, I still would purchase magazines."

Vendors sell about 13,000 magazines a month for $3.00 each.
