One year later, AT&T acquired Bellsouth for US $67 Billion. At this point, the YELLOWPAGES.com business was no longer a joint venture, instead, it became a wholly owned subsidiary of AT&T, also doing business as AT&T Interactive. In 2009, the YELLOWPAGES.com site was rebranded as YP.com.

The yellow pages are any telephone directory of businesses, organized by category rather than alphabetically by business name, and in which advertising is sold. The directories were originally printed on yellow paper, as opposed to white pages for non-commercial listings.

The name and concept of "yellow pages" came about in 1883, when a printer in Cheyenne, Wyoming, working on a regular telephone directory ran out of white paper and used yellow paper instead. In 1886, Reuben H. Donnelley created the first official Yellow Pages directory.
