If you look at things from a surfers point of view -- then the choice between a large MGP and a Tube site is a no-brainer. When a surfer hits a MGP they see a thumb they like, they click it, and get sent to some other site. They see another thumb on this new site, they click it, and get sent to another site, etc. etc. etc. The same surfer goes to a tube site, they see a thumb they like, they click it, they watch it. The surfer is happy! The surfer bookmarks the tube site and never goes back to the MGP.
Instead of adadpting and confronting the new reality of the web -- MGPs are carrying on like it is business as usual, whilst they lose their surfers, and their money. The MGP business model is in decline, and has passed it's maturity stage. The tube site has left it's development stage and is now in it's growth stage. As the tubes grow, and the MGP decline -- it is the failure of the MGP to change that is setting them up for continued failure and ultimately obscurity.
Here is a chart showing the rise of a medium sized tube site, and the decline of a very large MGP. Remember -- if you are not growing, you are shrinking. Names deleted to save embarrassment / conflict;
