AOL is offering its email, software, and other web services to high-speed internet users for free in an effort to boost its online sales.

This is the fourth overhaul in 5 years for AOL, which is struggling to adapt its business model in the high-speed internet era.

The free services will be ready in September, and will include a local phone number than can receive unlimited incoming calls.

AOL lost nearly a million subscribers in the second quarter, while its ad revenue rose 40%, Time Warner reports show.

In related news, the company is also going to preview its beta video portal site this week.

Like YouTube, it will function as a search and sharing video site, but it wants to offer the widest variety of clips found anywhere on the web.

The site will also offer more than 45 video-on-demand channels from content providers like The History Channel, MTV, and Warner Bros, and will host both free and download-to-own videos.

Like Blinx.tv, AOL’s video search will look for videos across the internet from sites including YouTube, Yahoo, and Google Video.
