Whole course lecture

A couple of weeks ago we went to a lecture where we had a guest speaker. His job was to analyse key areas of popular culture and create products/programs around it, for example he worked on a project for the BBC. This was the BBC Iplayer, the general gist i got (that i could understand) was that they worked out how many people watched a certain program and made announcements a advertising available to the public based on what was popular at that time, so if a program about fish was popular they would harness that information for their advantage. Maybe this is why we have so many cooking programs on television lately. I think i understood most of the lecture however i get the feeling i didn't quite grasp it, not many people asked questions but the ones who did asked the questions i would have. One of these questions was "is it competitive?" he answered with "extremely" he also went on to say that it is wise not to pigeon hole your creativity into one skill and branch out into more and more things. He also said that it is important to stay on top of what is in and not fall behind otherwise you will struggle. I already had an idea that this might be the case so that is why i need to really try my hardest at uni and away from it to hopefully get the job I've always wanted.
