Step-by-step explanation:
Let us understand the situation and analyze the inter-dependency and growth:
Initially, people like to watch movies on theater, because of big screens which was not available at home. Later on, home theater came into existence. Since the home entertainment has been created equivalent to theater, going to theater became second chance.
Now the theater has to introduce sounds like "Dolby ATOMS or other effects" to keep up the level. Now the trend is to watch film on mobiles through mobile applications.
Again now, theater has to think of few other alternatives like bringing additional comforts, luxuries and other entertainment for kids like small rides and games to attract the customer towards the theater.
So the technology and infrastructure changes plays major role.
