Why will all tv be going digital in February 2009? ?

Question

i saw a commercial for dtv and i am just curious as to why.

Answer 1

Digital technology for televisions allow for a sharper image and better sound quality, so we are changing to a digital signal also.  

The FCC will auction (sell) the old television frequencies after February 2009 to cellular providers so they too can improve their service.

Answer 2

Digital saves so much energy, that's why.

Analog television services have been a drain on power at main broadcasting centres for a long time.

Answer 3

because other tvs are old!!!!
