I think the future will hold more and more celebrity worship on every channel including our pathetic corporate news stations, with more sports shows and spin offs about celebrity news like TMZ and EXTRA. Personally I feel like TV is going to reflect exactly how uneducated and unintelligent the majority of our society gets. I think its going to directly covey what society holds most important-because thats what they want to hear about and watch.
About commercials, I don't know if they'll become more or less-or just morph into another form (split screen ads or shows directly advertising products/services within their programming). In any event, I don't plan on allowing my children to watch TV without me in the room due to the nature of commercials-especially those with similarities to carl's Jr. "god of hamburger" type of overtly sexual imagery.
I think all the big cable providers like verizon fios, direct tv time warner and at&t will merge until there are less than 3 because the mass consumer market will be looking for shows immediately (and commercial free) from providers like hulu and netflix and they'll get their news from the internet from whatever source agrees with their veiws.
I'm 26 and I didn't grow up with anything but basic programming--well, more like the 4 channels that could come through without too much static. I'm married now and I convinced my husband who grew up with the most elaborate cable type tv channels to save $ and try out basic programming. It works out well, we have at least 40 channels, of course some are in spanish and korean, but those I enjoy most are PBS, KCET and other similar public broadcasting stations. I only trust news from those sources too.
I bring that up because the only reason I even use television is for news (and emberrassingly, the simpsons), I can't really depend upon the internet due to the fact there is just so much information that I find unreliable. PBS has the best news, they often host guests with totally different opinions and give everyone equal air time. They don't spin anything because they don't have such a huge agenda to promote like CNN or FOX does.
ANyways... TV, interesting topic...
