In the case of television, yes, it has increased the amount of information in circulation, but it has also increased the amount of control and is therefore an anti-democratic technology which will have to be replaced before communism can properly take shape.
The internet gives me some cause for concern, as whilst it has created an explosion of information [god bless wikipedia, it's not accurate, but so useful], it is also concenrtrating that information into fewer hands (Google, Facebook, etc) and that kind of implies that net neutrality will be threatned in the future. The internet is challenging our existing social relations by undermining the nature of personal privacy, intellectual property and copyright, not to mention our sense of what is real and true (so many right-wing nuts on youtube!) and has made it much easier to practice mass surveillance...
I think automation- in absolute terms- is a good thing as it means people have to work less, but getting laid off does imply a future conflict between automation and wage labour under capitalism.
