Well, that depends. In the NFL, you play for 15 more minutes and whomever scores first wins. If no one scores, it's a tie... unless it's the playoffs. Then you keep playing 15 minute quarters until someone finally scores. / In the NCAA, there is no clock. Each team gets one posession at the opponent's 25 yard line.
Beginning in the 2010 NFL post-season, a modified sudden-death system for overtime games was put into effect. The overtime rules were changed to reduce the apparent advantage gained by the team that won the overtime coin toss. Under the prior rules, the team that won the coin toss would usually elect to receive the ball, then gain just enough yardage to win the game by kicking a field goal without the other team ever touching the ball. The modified rules allow both teams to have the "opportunity-to-possess," with one exception. The exception occurs if Team(A) scores a touchdown (not just a field goal) on their initial possession in overtime, then the game is over and Team(A) wins. But if a touchdown is not scored on Team(A)'s opening drive, or if they score only a field goal, then Team(B) is given an opportunity to possess the ball by either a punt, a kick, or by taking over on downs from Team(A). Of course, Team(B) could also gain possession by an interception or fumble from Team(A). Once the requirement for "opportunity-to-possess" has been satisfied by both teams then normal sudden-death rules apply, meaning that the next team to gain more points than the other team wins the game (note that it's possible for a tie score to occur during overtime play under these rules). Various events may occur that constitute "opportunity-to-possess" even though a team may not gain full possession of the ball in order to run a play. For example, if Team(B) muffs a kickoff or punt return (i.e., drops the ball while attempting to catch it) which is then recovered by the kicking Team(A), then Team(B) is considered to have had their "opportunity-to-possess," and normal sudden-death rules would then be in effect. Similar to normal overtime, following a three-minute intermission after the end of the regulation game, a coin flip is performed wherein the captain of the visiting team calls the toss. However, in post-season overtime, multiple 15-minute overtime periods may be played until a winner is declared.
Football over time is 60 minutes long
Unlimited sudden-death overtime has been used in the playoffs to determine winners since the early years of the NHL. The five minute overtime used in the regular season was introduced in 1983/84 season.

In college football, yes. If the score is tied at the end of an overtime period, the game continues. Overtime rules in college football are set up so that there cannot be a tie game ... overtime periods will be played until one team is ahead at the end of an OT period. In the NFL, not in the regular season. If no team scores in the overtime period, the game ends and is declared a tie. Obviously, in the playoffs there can be a double overtime as those games must have a winner.
no
Overtime was implemented in the 1974 season for regular season games. Before that there was no overtime to break a tie in a regular season game. Of course, playoff games have always had overtime.
Because there was no overtime in college football yet.
