Interesting to see how many watch the old fashioned way / do not watch at all - Which is basically how I 'watched' F1 the first 10 - 11 years of being a fan - a snip less than a minute at the end of Sunday Sport "Today John Watson won the Austrian Grand Prix", followed by John Watson crossing the line, reading the top 5 in the newspaper next day, and then eagerly await the next race... We did get somewhere between 1 and 3 races in a season, which a failing memory wants to make Monaco, Italy and sometimes one more.
The Free To Air some demand has not really been the case for many, many, many years. There is always a cost in UK you pay something for BBC, in Denmark we paid (well parents did) the annual license fee, we did not get a second Danish TV Station until October 1988... From sometime early 80ies my brother and I started sourcing more reading materials - Auto Motor und Sport, Motorsport, Grandprix a sliver of smaller Danish, Swedish and German magazines, Road and Track and bought a subscription for Autosport, the 'bible' of our following the sport.
Looking back, I do not think I had the option of following a full season on TV until 1997 meaning making it to 34 before I actually had Free to Air - Which still entailed a cable package costing some thousands of Danish Kroner each year. As I posted further up, I follow on ESPN2 which is the Sky broadcast served up with Zero commercials which is for all intents and purposes unheard of in the US, but I take it - If I am home and have the time I watch it live, including getting up at an early hour to watch the Australian Grand. If I do not have the time I watch it later in the day from the DVR, living in the US have the benefit of no media telling me the result before I watch.
