The long Hollywood award season is finally hitting its climax with the 90th addition of the Academy Awards on Sunday night. Jimmy Kimmel will host this year's ceremonies, scheduled to start at 8 p.m. ET on ABC. Pre-show coverage of the red carpet at the Dolby Theatre varies by network, but ABC will have its dedicated "Live From the Red Carpet show" on air beginning at 6:30 p.m. ET. But pinpointing when it will end is the trickier part.

The end of the Oscars has become can't-miss TV. Remember last year? La La Land was mistakenly given the best picture award when Moonlight was the actual winner. Chaos ensued and viewers everywhere were treated to an all-time great moment in live television.

ABC has budgeted a tidy three hours to the event, taking the broadcast to an 11 p.m. ET end time. Based on speeches and other variables, telecasts often run long.

The longest telecast came in 2002, which ran for 4 hours, 23 minutes. Viewers had to wait for over 3-and-a-half hours to witness last year's dramatic end. Each Oscars telecast since 2013 has graced our screens for over that 3-and-a-half-hour mark, with an average time of roughly 3 hours, 40 minutes, which would bring this year's telecast to finish around 11:40 p.m. ET, surpassing it's budgeted slot. So, adjust those DVRs or grab a cup of coffee if you're planning on staying with the telecast for the long haul.
