In the early 1990s, Tesco made plans to extend its range into non-foods. Helped
by continuing improvements in supply chain management and collaboration, it
was able to free-up valuable retail floor space previously required for in-store
warehousing. In 1994, Tesco introduced a music and home entertainment
department, offering popular ranges of compact discs, videos, books and
stationery. By 2004, Tesco had a 19 per cent share of chart music sales, up
from 7 per cent five years previously.
