Open Production and Closed Production

We were given two examples of collaborative production, those are Wikipedia and Encyclopedia Britanica. Both of them are available online and have many information in their servers, so you can find almost everything you are looking for. It shows us that they are open sources. But for me, to the guy who used Wikipedia for a log time to find what I want when I need to, Britanica seems to me as a very primitive and not so interesting website, and it does not even have some simple stuff that most people want to know. On the other hand Wikipedia is really easy to use and consist of many-many different articles and news that make people to pay attention when they enter the site. Even when you search something at Google it gives you a link(s) straightly to Wikipedia. I am not actually saying that Britanica is boring and unuseful, but the problem is that Wikipedia is more popular at the moment rather than the other one. Perhaps it should take some particular period of time to Britanica to become as popular as Wikipedia.
