In 2000, Forrester counted 43.8 million households that are online. The next year this rose to 58.8 million, and in 2002 the number reached 63.6 million. This year, 67.5 million households will have gone online. Yet while the number of households online has risen steadily, the percentage that buy online is relatively unchanged. Half of those households online in 2000 shopped in that medium. It dropped to 49% in 2001, before rising marginally to 51% in 2002 and this year. Forrester found the number of product categories purchased online has risen from 4.4 in 2000 and 6.6 in 2001 to 7.5 in 2002 and 8.1 this year.
