In the 1980s, the neighborhood changed demographically from one of Italian, Irish, and Modern Orthodox Jewish to Hasidic Jewish families. By 1983, an estimated 85 percent of the residents of Borough Park were Jewish. New shops and restaurants opened on 13th Avenue to serve the expanding Orthodox Jewish community. In 1987, two of the most popular stores debuted: Eichler's Judaica bookstore, and Kosher Castle Dairy Cafeteria. New stores also opened selling imported goods and computer technology. At the end of the 1990s, businesses began selling electronics and Jewish books, music, and videos to overseas customers via the Internet. The area continued developing into a very large Jewish enclave around that time period.
