While TV ratings for the impeachment hearings peaked on the first day of testimony from Bill Taylor and George Kent, none drew as much online attention as former ambassador to Ukraine, Marie Yovanovitch, according to data from NewsWhip.

Why it matters: Democrats hoped to sway public opinion with revelations about a smoking gun of Trump's involvement in a quid pro quo, but the numbers highlight the power of an emotional appeal.

Yovanovitch became a sympathetic figure to many over perceptions that she was wrongfully removed from her post.

Yes, but: Since she had been removed from her post by May, Yovanovitch couldn't speak to central details around the impeachment inquiry focused on events in July.

The big picture: TV ratings steadily declined over the course of the 5 days of hearings, according to Nielsen data.

The first day of testimony pulled in 13.8 million viewers and Yovanovitch got 12.7 million.

Tuesday and Wednesday of this week both got 11.4 million viewers. Thursday's hearing pulled in 11.3 million.

By comparison to other big Trump-era television events:

Christine Blasey Ford/Brett Kavanaugh: 20 million

James Comey: 19.5 million

Michael Cohen: 15.8 million

Robert Mueller: 13 million
