My review regarding the logo change/revamp:
Firstly, I personally liked Sony Pix logo. It looks premium and professional and is very much suitable for an English channel. The graphics are also fine and attractive.
Coming to other channels, Sony SAB has the best logo (including the font in which the word SAB is written), and the graphics are too good and different.
Sony Max, which was very much in need of a revamp, IMO has got a perfect revamp where the logo and graphics are quite soothing and attractive; better than other channels.
Sony Max 2 logo and graphics is also good and they have made good use of Purple color for their graphics. Sony Wah logo looks quite messed up and graphics are ok.
Sony Pal logo is ok and I'm quite impressed with their graphics package. Coming to Sony Marathi, the logo looks fine but then I had expected the word Marathi (मराठी) to be written in a different font. Graphics look quite similar to the previous one.
Special appreciation to Sony Aath. I was highly impressed by their graphics package. They have included all cultural elements which portray Bengali culture. It is also very attractive. The logo is also good.
Sony Sports channels logos are fine (except for the word Ten written on the logo) and graphics are also attractive. Sony Yay logo is not that great and could have been better.
Lastly, coming to Sony TV, I am quite disappointed mainly with the graphics. This was a much needed revamp for Sony TV as well after 6 years. The logo is somewhat good and the size is perfect. The graphics look very similar to the previous one. They could have used different colors apart from the previous colors (dark purple and golden yellow). Also, a different theme music was expected, which wasn't changed.
Concluding, I was happy with the revamp and was also disappointed wrt to some channels.
