According to XO Group Inc., a global media and technology company and creator of the wedding website TheKnot.com, wedding traditions continue to evolve. In its 2013 Real Weddings Study, a comprehensive report in which nearly 13,000 brides and grooms married in 2013 in the United States were surveyed, TheKnot.com found that couples are increasingly modernizing their nuptials and, consequently, leaving many once cherished traditions in their wake. Nearly 75 percent of couples surveyed admitted to living together prior to tying the knot, a living arrangement that might once have been a societal taboo but is now gaining greater acceptance. In addition, more and more couples are not marrying in religious institutions, as just 33 percent admitted to doing so in 2013, marking an 8 percent decrease from 2009. Another rising trend concerns the tradition of brides taking their groom's last name. While 86 percent of brides took their new husband's last name in 2009, by 2013 that figure had dipped to 80 percent.
