Movies, Concert and Broadways

I am a certified movie goer and if i find a movie interesting, i always make sure that i watch it on its premiere night on theaters. But of course, i am not the most powerful man in this world and i cannot always get the theater tickets in an instant. I have to work hard for it ,i have  fall in line in an endless crowd just to reach the ticket booth. Unlike concerts and Broadways,  you can just call their hot line and reserve tickets for you. However, there is also a huge differences between the process on how to get a concert ticket and how to get a Broadway theater tickets. Concert  tickets were sold on a limited time while Broadways were sold in limited yet long period of time ( as long as the Broadway runs). There are also sites that offers theater tickets showing the list of all shows running from different places worldwide.
