Com a proibição do tráfico negreiro e a abolição da escravidão, em 1888, começaram a chegar os imigrantes, vindos de diversos países para substituir a mão de obra escrava. Como a situação na Europa estava difícil e o Brasil era visto como um país cheio de possibilidades, eles chegaram trazendo grandes expectativas de construir uma vida nova. Era muito comum a expressão “vamos fazer a América” entre os imigrantes europeus que vinham para o Novo Continente. Com eles vieram também seus sonhos, seus costumes e tradições.

Frequently Asked Questions – Instagram

    What is Instagram?

    It’s an application for your mobile phone that enables you to edit pictures you have taken with your mobile phone camera using built-in filters and share them with others. If you have an Instagram account you can tag pictures, rate and comment on other people’s pictures and follow other users.

    How much is your app?

    $0.00.

    Where does the name come from?

    When we were kids we loved playing around with cameras. We loved how different types of old cameras marketed themselves as “instant” - something we take for granted today. We also felt that the snapshots people were taking were like telegrams in that they got sent over the wire to others - so we figured why not combine the two?

    How did the idea come about?

    We love taking photos. We always assumed taking interesting photos required a big bulky camera and a couple years of art school. But as mobile phone cameras got better and better, we decided to challenge that assumption. We created Instagram to solve three simple problems:

    - Mobile photos always come out looking mediocre. Our awesome looking filters transform your photos into professional-looking snapshots.

    - Sharing on multiple platforms is a pain - we help you take a picture once, then share it (instantly) on multiple services.

    - Most uploading experiences are clumsy and take forever - we’ve optimized the experience to be fast and efficient.

    How does privacy work?

    We have adopted a follower model that means if you’re “public” on Instagram, anyone can subscribe to follow your photos. We do, however, have a special private option. In this mode, a user can make sure he/she must approve all follow requests before they go through.

    Who can see my photos?

    All photos are public by default which means they are visible to anyone who has an account. If you choose to make your account private, then only people who follow you on Instagram will be able to see your photos.
