I am trying to remember, who exactly was pushing so hard for teams to move to Los Angeles.
1.) Was it the NFL owners, who thought they each would reap the financial benefit from a relocation fee?
2. ) Was it individual owners seeking a sweetheart stadium deal like the Niners, Bucs and others had been able to wrangle from local municipalities?
3.) Was it the networks, who felt having team(s) there would result in higher ratings and therefore more advertising revenue?
If it was #3 then the networks should have done better research. From this 2011 article there are conflicting viewpoints on that topic.
NFL in L.A. is a ratings conundrum
“There’s definitely an impact nationally and locally,” notes Bill Wanger, exec VP of programming and reseach for Fox Sports Media Group. “From a local standpoint, you’re talking about more than doubling the rating for a home team in L.A. vs. a neutral game. It’s definitely a benefit on the O&O side.”
However, there was also this opposing viewpoint:
Ad buyer Gary Carr of Targetcast thinks his clients won’t be affected much whether there’s an L.A. team or not, and no matter how good that team is. The NFL is an 800-pound gorilla gaining weight, and one or two teams changing cities shouldn’t make much of a difference from an ad perspective.
“I don’t see an earth-shattering change,” he says. “The NFL ratings are pretty damn high as it is.”
Los Angeles seemed completely disinterested in bringing an NFL team back to the area for years. It seemed as though the demand was a fabrication from outside the region. The logic was based strictly on the population for the metropolitan area, and all other factors were excluded.
As for the sweetheart deal the 49ers received for their new stadium, they are not alone. This article lays out a lot of the facts about how they and many other owners have hoodwinked local authorities.

Despite all that the 49ers apparently just couldn't help themselves, and wanted to keep even more cash for themselves.
