Reportedly, Australian retailer Kogan will now be charging an Internet Explorer 7 tax -- currently at 6.8% and set to raie 0.1% each month -- in order to "recoup the time and costs involved in 'rendering the website into a antique browser'.."

Mr Kogan said that even though only 3% of his customers used the old version of the browser, his IT team had become pre-occupied with making adaptations to make pages display properly on IE 7.

"I was constantly on the line to my web team. The amount of work and effort involved in making our website look normal on IE7 equalled the combined time of designing for Chrome, Safari and Firefox."
