HitWise just released data showing MySpace.com is now the most visited domain for US users.

Today Hitwise issued a press release reporting that for the first time, www.myspace.com has surpassed Yahoo! Mail as the most visited domain on the Internet for US Internet users. To put MySpace’s growth in perspective, if we look back to July 2004 myspace.com represented only .1% of all Internet visits. This time last year myspace.com represented 1.9% of all Internet visits. With the week ending July 8, 2006 market share figure of 4.5% of all the US Internet visits, myspace.com has achieved a 4300% increase in visits over two years and 132% increase in visits since the same time last year.

The chart below shows the growth of visits to myspace.com compared to google.com over the last several months:

Also, more people are searching for MySpace as Bill Tancer shows the search querys as being a much higher percentage of search share than they were just a year earlier.

Of all the charts I can replicate, Alexaholic Traffic Rank is the closest to HitWise’s charts - and confirms that MySpace is moving up - but does not tell you that MySpace is more visited than Yahoo.
