I can still remember when summer reruns were the only way to catch a missed episode of a favorite TV series.  Each year I would carefully plot my summer TV watching schedule so I could make sure I got to see every show.  That was before I realized I can watch TV on the Internet.  First I found a website where I can watch that 70s show free online, then I expanded my search to find other online TV.  Now I never worry about missing an episode of anything, because I know I can see it whenever I get a little free time, at no charge, on the Internet.
