Effects of the Internet on Cubism
There are both positive and negative websites on the Internet, which not only affect Cubism, but all art as well.  Many sites are based on artists, such as Pablo Picasso.  They are based on the life and works of art, of that particular artist, which also talks about the style of Cubism and the artists' thoughts based on Cubism.  And others are about selling the art, discussing the art or just simply viewing the art, whether it be original or reproduced.  Take a look. 
I found a site called the
"On-Line Picasso Project" by Dr.Enrique Mallen, which discussed the life of Pablo Picasso and displayed and discussed all of his art work and books, in chronological order.  There are obviously a million other sites based on artists ,like Pablo Picasso, biography's, but none of them were as organized and well detailed as this site. 
The Internet has become one of the most popular places to buy products, especially art.  The art comes as replicated or reproduced art, in any shape or form (posters, paintings, etc), depending on the buyer.  In the website,
http://www.arts-studio.com , the company offers their buyers hand-painted reproduced art for a "reasonable" price.  Depending on what site you're on, the prices defer and depend on what you're getting, such as a painting or a postcard.  I actually went to about 20 sites where reproduced art was being sold, but more or less, they were all the same.  On the other hand, at http://www.picassomio.com , the company sells the real thing, all of their art is original and authentic.  They give their guarentee and even offer their customer's a signed "Artist's Authenticity Statement", as proof that the art was actually painted by a specific artist.  I happened to find some Cubism art on the site. PabloPicasso's "Visage Pour Dora Mor", which is a small sketch of a person's face,  costs $2250 (US).
Some other sites were: http://www.cubism-asada.com, which shows some modern Japanese forms of Cubism.  This a very interesting site, which displays many new Cubism skteches and even scultures.  Take a look by clicking on the link above. 
Also, there are actual museum sites, such as New York museums and the
Peggy Guggenheim museum situated in Italy, which holds paintings by Picasso and Braque.

Try to spend some time on viewing the above sites.  I promise, you won't regret it!

I also managed to find many new artists whose interests lie within the art of Cubism.  One site, http://www.picassoman.co.za , shows and sells Eugene Slabbert's Picasso-like paintings.  Take a look at one of his many Cubism art pieces.
