what's going to eventually happen is dynamic channel switching, a return to the old days when youi "paid" for channel 6 while you watched it (in the 50s, by watching commercials and maybe trying the Swanson's dinner sponsoring the program.) in other words, customers either create their OWN bundles, or from the availiable channels, they pick what they want now, and are post-view billed for the usage. there will be no free rides in the 210-channel bundle for the Disney Outtakes Channel, or ESPN 17: pick-up soccer at Evanston South Elementary School.
at that point, you won't have 210 channels. but of the 100 you do have, they will be one ones that got watched historically, and are not vampires positioned in provider contracts because "I don't want to be the guy with only 6 slots on the satellite, I need 20 to get ads."
