A year has now passed since Barack Obama took office as president of the United States.
But for generations of African-Americans, a black US president was considered to be an impossible dream.
A year ago the BBC met civil rights veteran Dr Terrence Roberts and his family to ask them how they felt about President Obama's inauguration. Roberts was one of the Little Rock Nine students who were the first to integrate the city's racially segregated schools in 1957.
Now as Obama celebrates his first anniversary we revisit Dr Terrence Roberts, his daughter Rebecca Goodloe and grandson Paul Goodloe Jnr.
They share their thoughts on subjects ranging from the economy and the war in Afghanistan - to the notorious incident when Obama accused a white police officer of acting "stupidly" in arresting a prominent black professor, before inviting the officer and the professor to the White House for a beer.
