Statistics to wow non-techies about digital future

A common question I get from non-techies is “Is ecommerce for real? Do people really buy online?”

My line of argument is that the future is digital, and hence buying
online is a natural consequence of that.

However, just saying that was not convincing enough. So I gathered some
statistics as proof and to wow them:

• Apple iTunes is the largest music retailer in
  USA and has sold
  more than 10 billion legal songs as of Feb
  2010
• Amazon is one of the largest book selling websites in the world and
  it now sells 105 ebooks for every 100 printed books it
  sells
• Netflix is a movie streaming company and accounts for 25% of North
  American Internet
  traffic
• Facebook is actually the largest photo sharing website in the world
  where the average user creates 90 pieces of content each
  month and 100
  million photos uploaded per day / 6 billion photos uploaded each
  month

Closer to home:

• 55 million hits in 48 hours for Zindagi Milegi Na
  Dobara
  via mobile phones, facebook and youtube only, the killer part is
  that no TV ads were done as a deliberate marketing strategy
• Gujarat just voted via the
  Internet
• 20 million people watched IPL
  online
• Despite the super high
  costs,
  India has 9 million 3G users
  already
• Update: Less than 1% of India’s population uses 3G service. 0% used 3G a year ago and 30% will use it 4 years from now → 400 million new smartphones.
• Update 2: According to a McKinsey report titled ‘Internet matters: The Net’s sweeping impact on growth, jobs, and prosperity’, released at the e-G8 Forum held in Paris on May 24-25, 2011, internet contributed 5 per cent to the total gross domestic product (GDP) growth of India in the past five years compared with the average 3 per cent for BRIC (Brazil, Russia, India and China) economies. According to the report, companies are able to keep costs down, target customers better and bring goods and services to markets around the world much more easily. — AlooTechie

Then there always is the trump card of how ubiquitous online ticketing has become…

As you can see, digital is happening in India and with RBI
reporting that 35% of transactions (and 88% of the total amount) were
electronic
and Cash on Delivery slowly
happening,
how far will ecommerce
be
behind?

How would you convince someone that the future is digital and that ecommerce will be big in India?
