Twenty-five years ago, most young British people wanted a career in law, to be a doctor, or to take up singing. But today, things stand {#blank#}1{#/blank#}(different).

According to a recent survey, the "dream job" of young people {#blank#}2{#/blank#}(age) between 16 and 25 in the UK is a video blogger, or "vlogger(视频博主)". The survey, carried out among 1, 002 people, found that over 40% of them put vlogger as their number one choice on a list of dream {#blank#}3{#/blank#}(career).

The change is largely due to the rapid development of information technology (IT). The Internet and social media have made it {#blank#}4{#/blank#}(easy) and more convenient to reach a global audience, without having to enter a career in show business in the traditional way.

"In the past, the biggest stars {#blank#}5{#/blank#}(make) by the Hollywood studios; now, anyone with a computer camera may become a star, " said Phil Samuels, {#blank#}6{#/blank#} expert from the UK. "From fashion to comedy, these self-made stars interact online with their fans about everyday life. "

However, what people see {#blank#}7{#/blank#}(be) only the bright side of being a vlogger and they ignore the fact {#blank#}8{#/blank#} only those who are successful can gain fame and fortune. Actually, {#blank#}9{#/blank#} every success there are a hundred others who never get off the starting block. This is why some young people still show {#blank#}10{#/blank#}(prefer) for traditional jobs.
