The Beatles are and were the greatest cultural occurrence of the 20th and 21st century so far.

I think the Beatles are and were awesome, to the point where I feel it is the greatest thing human culture has ever witnessed in the past 108 years. Anyone who believes otherwise should take the con side.
Thank you.

Thanks for starting this debate and best of luck.

To begin, I'd like to offer up a few definitions for clarification:
______________________________________________________

6. Of outstanding significance or importance: a great work of art.

Greatest: Superlative of "Great"
(Superlative - something has some feature to a greater degree than anything it is being compared to)

My opponent makes the assertion that The Beatles (as more or less an event) maintain the highest level of significance or importance in human culture within the last 108 years. Thus I must negate. Given this premise, it is clear that I need only offer ONE event (occurrence) that has had a greater impact to human culture in order to win this debate.

It is clear that there have been many events which have molded and reshaped human culture more so than The Beatles. Societal behaviour patterns, arts, beliefs, and institutions have been so vastly affected by inventions and introduction into human daily life of various products. To name just a few:

1902: Large Scale, production-line manufacturing of affordable automobiles.
"As of 2002, there were 590 million passenger cars worldwide (roughly one car per eleven people).[4]"(http://en.wikipedia.org...)

1903: Invention of an Airplane able to navigate a controlled, sustainable flight. The invention of the airplane eventually lead to the revolutionization public travel, warfare, space exploration, etc.

1940's: World's first operational computer later leading to the Personal Computers we all use today.
"As of June 2008, the number of personal computers worldwide in use hit one billion, while another billion is expected to be reached by 2014"(http://en.wikipedia.org...)

1990's: Introduction of Internet to public usage
"As of March 31, 2008, 1.407 billion people use the Internet according to Internet World Stats."(http://en.wikipedia.org...)

I challenge my opponent to make a rational case in which he can objectively prove, or at least convice that audience, that The Beatles have made a GREATER impact on human culture than any of the above. So far my opponent has not substantiated this claim, and has only offered up feelings and opinions. While these are not my only contentions, I will await his retort before continuing further.

Unfortunately my opponent was unable to respond, therefore I'll ask that my arguments be extended through this round. As previously stated, my opponent is in a precarious position to justify such an audacious claim.

My opponent has failed to post a reply, and in doing so has not substantiated his original claim (opinion). It is therefore only logical to vote CON.

Thanks.
