advertisement plays a big role in our lives. some people don't like to see it everywhere and some people don't care about it. as for me, i think that  advertisement is an inportant part of our world. to keep the economy up we have to sell goods to people but it would be inpossible to sell a lot of products without advertising it. but i believe that it should be limited. i can't stand when i am in museum or theatre or any other cultural place and there i see commercial everywhere around me. i also don't like when i watch an interesting movie and it is interrupteb by a commercial. so my opinion is that the advertisement should have a right to exist but it should be limited.
