What does this mean for the smaller players?

I want to be a director someday, and recently while I was at the movies I noticed that the film was produced by Warner Bros., but MGM was included as well. Something I noticed that was interesting was that under the MGM it said a Time Warner Company. This sparked my interests because I always knew of the MGM Company being one of the major players in the film industry. Being curious I decided to read up on the subject. The information proved to be very interesting. Turns out that MGM had to file bankruptcy and went up for sale. Warner Bros. studios decided to buy a piece of the pie. As I was reading about this information it made me think, someday is there only going to be a small number of studios around, and if so what does this mean for independent studios or ones that are just getting started? This incident isn’t going to stop me from pursuing my dreams of working in the industry. Even though it is somewhat scary thinking that one of the first major studios had to file bankruptcy and be bought out, but that shouldn’t stop people who want to try and start their own companies. Wanting to be a director I won’t have my own studio, but someday I could potentially want to have my own studio. Hopefully if studios go bankrupt, their names won’t be lost, so that generations after can know who were the major players and got the industry started.
