The countdown clock will come to an end Sunday for MTV's flagship series "Total Request Live," and fans of the show are struggling to say goodbye.

Damien Fahey, the long-time host of the pop culture barometer, said: "It's the end of an era for a lot of fans."

At its peak in 1999, "TRL" averaged 761,000 viewers a day, according to Nielsen Media Research. So far this year, the show averages 322,000 viewers a day.
