Highest number counted out loud

In 2007 Jeremy Harper, of Birmingham, Alabama, verbally counted every number up to a million, in a series of live internet broadcasts spanning four months – highlights of which are still available on YouTube (http://bit.ly/cOT1IC). Starting on 18 June 2007, he counted for approximately 16 hours a day, finally reaching one million on 14 September that year – a total duration of 89 days, and averaging just over 11,200 numbers per day.

For the entire duration of the record attempt Harper did not leave his flat, nor shave. He raised over $10,000 in donations to the disability charity Push America – and meanwhile paid his living expenses by selling advertising on his website.
