Google is doubling the storage capacity of its Gmail service to 2GB in a further move that is bound to shake up the web-based e-mail market.
Although Gmail is still in limited beta format one year after its official launch, it has been setting the market agenda.
Before Gmail came along, MSN Hotmail and Yahoo users got only 2MB and 6MB respectively of free e-mail storage. Both sets of users now get 250MB of free storage.
To get 2GB of e-mail storage Yahoo users currently have to pay £11.99 a year.
Google, MSN, Yahoo, AOL and others are all competing in the growing search engine advertising market, and providing attractive web e-mail offerings is one way to get users to look at ads within their portals.
