Bernadette Coveney Smith, owner of LGBT wedding-planning company 14 Stories, said her business doubled after same-sex marriage was legalized in New York in 2011.
New York City Mayor Michael Bloomberg's administration said that the city issued more than 8,200 marriage licenses to gay couples in the first year after New York legalized same-sex marriage—about 10 percent of all licenses issued. The mayor's office estimated that related spending, including visits by out-of-state couples seeking to get married, totaled $259 million in that time period.
